Scope

onsemi tau pioneered cov kev taw qhia ntawm SiC JFETs nyob rau hauv ib tug cascode configuration nrog rooj vag tsav compatibility rau Si MOSFETs, IGBTs, thiab SiC MOSFETs, raws li nyob rau hauv 5 V pib vol.tage thiab dav qhov rooj ua haujlwm ntawm ± 25 V.

Cov khoom siv no yog qhov hloov pauv sai heev, nrog rau cov yam ntxwv zoo ntawm lub cev diode. onsemi tau ua ke lub advantageous SiC JFET raws li cov khoom siv hluav taws xob nrog kev lag luam tus qauv hluav taws xob module pob, E1B, txhawm rau txhim kho lub zog ceev, kev ua haujlwm zoo, tus nqi-zoo, thiab kev yooj yim ntawm kev siv rau cov tshuab fais fab.

Daim ntawv thov no qhia txog kev taw qhia mounting (PCB thiab heatsink) rau onsemi qhov tseeb E1B fais fab module pob (ib nrab choj thiab tag nrho tus choj).

TSEEM CEEB: Snubbers tau pom zoo rau SiC E1B modules vim lawv qhov kev hloov pauv ceev ceev. Tsis tas li, snubber zoo heev txo qis kev hloov pauv poob ua SiC E1B modules txaus nyiam heev hauv ZVS (zero voltage tig-on) soft-switching applications xws li theem-hloov tag nrho-bridge (PSFB), LLC, thiab lwm yam.

Cov khoom no raug pom zoo rau kev siv nrog solder pin txuas thiab theem hloov thermal interface cov ntaub ntawv, thiab tsis pom zoo rau kev siv siv xovxwm haum thiab daim ntawv thov ntawm thermal roj. Thov xa mus rau mounting cov lus qhia thiab cov ntaub ntawv qhia cov neeg siv cuam tshuam nrog cov khoom no kom paub meej cov ntaub ntawv.

Daim ntawv thov no tseem muab cov peev txheej txuas rau cov qauv simulation, cov txheej txheem sib dhos, cov yam ntxwv thermal, kev ntseeg siab, thiab cov ntaub ntawv tsim nyog.

Mounting PCB rau Module

Thaum lub PCB yog soldered ncaj qha rau sab saum toj ntawm lub module, cov neeg kho tshuab kev nyuaj siab yog tam sim no tshwj xeeb tshaj yog nyob rau hauv lub solder joint. Txhawm rau txo cov kev ntxhov siab no, ib qho ntsia hlau ntxiv tuaj yeem siv los kho PCB rau hauv plaub qhov kev sib tw ntawm lub module, saib daim duab 5.
Cov modules tau sib xws nrog tus kheej tapping screws (M2.5 x L (mm)), nyob ntawm PCB thickness.

Qhov ntev ntawm cov xov nkag mus rau hauv lub qhov taub yuav tsum muaj qhov tsawg kawg nkaus ntawm Lmin 4 hli thiab qhov siab tshaj plaws ntawm Lmax 8 hli. Nws raug nquahu kom siv lub tshuab hluav taws xob tswj hluav taws xob los yog lub tshuab hluav taws xob los xyuas kom meej qhov tseeb.

Mounting Module rau Heatsink

Heatsink Requirement
Qhov saum npoo ntawm heatsink yog qhov tseem ceeb ntawm tag nrho cov cua sov hloov mus rau qhov system thiab yuav tsum muaj kev sib cuag nrog lub heatsink. Module substrate nto thiab lub dab dej kub yuav tsum zoo ib yam, huv si, thiab tsis muaj kab mob ua ntej mounting. Qhov no yog los tiv thaiv voids, kom txo tau lub thermal impedance thiab ua kom lub zog ntau npaum li cas yuav dissipated nyob rau hauv lub module thiab mus cuag lub hom phiaj thermal kuj raws li datasheet. Lub heatsink qhov zoo ntawm qhov chaw yuav tsum tau ua kom muaj thermal conductivity zoo raws li DIN 4768-1.

• Roughness (Rz): ≤ 10 m
• Flatness ntawm lub heatsink raws li qhov ntev ntawm 100 mm: ≤ 50 m

Thermal Interface Material (TIM)
Cov khoom siv thermal interface siv nruab nrab ntawm cov ntaub ntawv module thiab heatsink yog qhov tseem ceeb kom ua tiav qhov kev ua tau zoo thiab ua haujlwm zoo thermal. Thermal grease lossis thermal paste tsis pom zoo rau lub hauv paus-tsawg module zoo li E1B.
Yog tias tsis muaj lub hauv paus tooj liab tuab ua rau lub tshav kub sib kis, lub thermal roj twj tso kua mis tawm (los ntawm thermal expansion thiab contraction ntawm TIM txheej ntawm module case thiab heatsink thaum lub sij hawm lub zog cycling los yog kub cycling) exacerbates void tsim nyob rau hauv lub TIM txheej thiab muaj kev cuam tshuam tsis zoo rau lub hwj chim cycling lub neej ntawm lub module.

Hloov chaw, TIM siv cov khoom hloov pauv tau pom zoo rau E1B modules. Daim duab 7 qhia tau hais tias lub zog cycling tau tshwm sim rau 1200 V 100 A ib nrab-bridge module (UHB100SC12E1BC3N) siv ob txoj kev sib txawv, thermal roj vs cov khoom hloov theem. Kab rov tav axis qhia tau tias muaj pes tsawg lub voj voog. Lub axis ntsug qhia cov cuab yeej VDS thaum Tj_rise ntawm 100 ° C. Qhov nkhaus liab qhia lub zog cycling nrog thermal roj. Qhov nkhaus xiav qhia tau hais tias lub zog cycling nrog cov khoom hloov theem. Txoj kev nkhaus liab tsuas tuaj yeem mus rau 12,000 lub voj voog ua ntej thermal runaway tshwm sim vim thermal resistance degradation los ntawm thermal roj twj tso kua mis tawm. Rau tib lub E1B module siv cov khoom hloov pauv rau heatsink TIM txhim kho lub zog cycling tshaj 58,000 cycles.

Daim duab 8. E1B Module Fais Cycling Test (a) Teeb, thiab (b) Test Conditions

Feem ntau, tom qab kev txhim kho tshuab, cov khoom hloov theem yuav tsum tau muab ci rau hauv qhov cub kom tso cai rau TIM hloov nws cov theem kom ntxiv cov voids microscopic ntawm cov ntaub ntawv module thiab heatsink thiab txo thermal kuj los ntawm module rooj rau heatsink. Nyob rau hauv lub saum toj no example qhia nyob rau hauv daim duab 7 thiab daim duab 8, thermal kuj los ntawm cov khoom sib txuas mus rau dej yog txo los ntawm 0.52 ° C / W rau 0.42 ° C / W tom qab 1 teev ci ntawm 65 ° C. Thov nrog TIM tus neeg muag khoom kom paub cov lus qhia ntxaws.

CEEB TOOM: Txhua theem sib txawv ntawm cov khoom siv yuav tsum raug soj ntsuam thiab kuaj ntxiv los ntawm tus neeg siv khoom los ntawm kev ua raws li cov lus qhia los ntawm TIM (theem hloov khoom siv) tus neeg muag khoom kom ntseeg tau tias kev ua haujlwm zoo

Mounting Module rau Heatsink
Cov txheej txheem mounting kuj yog ib qho tseem ceeb los lav qhov kev sib cuag zoo ntawm module thiab heatsink nrog rau theem hloov khoom nyob nruab nrab ntawm. Nco ntsoov tias heatsink thiab module yuav tsum tsis txhob kov thoob plaws hauv cheeb tsam kom tsis txhob muaj kev sib cais hauv cheeb tsam ntawm ob qho khoom. Table 2 cov ntsiab lus mounting cov lus qhia rau heatsink txuas.

Table 2. onsemi SiC E1B MODULE HEATSINK MOUNTING RECOMMENDATIONS

Lwm qhov kev txiav txim siab Mounting

Tag nrho qhov system ntawm lub mounted module yuav tsum tau xav txog. Yog hais tias lub module raug txuas mus rau lub dab dej kub thiab lub rooj tsav xwm Circuit Court, tag nrho cov khoom yuav ua tiav.
Kev ntsuas tsim nyog yuav tsum tau ua kom txo qis kev vibration ib yam nkaus vim tias PCB yog soldered nkaus xwb rau module.
Tsis muaj zog soldered terminals yuav tsum tau zam. Tus pins tus kheej tuaj yeem tsuas yog thauj khoom ntawm qhov chaw rau lub dab dej kub nrog qhov siab tshaj plaws, nruj, thiab qhov kev ncua deb txaus ntawm PCB thiab heatsink yuav tsum tau soj ntsuam los ntawm tus neeg siv khoom daim ntawv thov.

Txhawm rau txo qhov kev ntxhov siab ntawm cov neeg kho tshuab ntawm PCB thiab module, tshwj xeeb tshaj yog thaum PCB muaj cov khoom hnyav, nws raug nquahu kom siv qhov chaw ncej, saib daim duab 9.

Daim duab 9. E1B Module PCB thiab Heatsink Mounting nrog Chaw Tshaj Tawm

Qhov pom zoo qhov ntev (X) nruab nrab ntawm qhov chaw ncej thiab ntug ntawm PCB mounting qhov yog ≤ 50 mm.
Nyob rau hauv cov ntaub ntawv ntau modules yog mounted rau tib PCB, qhov siab variation ntawm modules yuav ua rau mechanical stresses ntawm lub solder sib koom. Yuav kom txo qis kev ntxhov siab, qhov pom zoo qhov siab (H) ntawm qhov chaw ncej yog 12.10 (± 0.10) hli.

Clearance thiab Creepage Requirement

Qhov sib txawv ntawm qhov sib dhos ntawm cov khoom sib dhos ntawm lub module thiab PCB yuav tsum ua kom tau raws li qhov kev tshem tawm thiab kev nkag mus deb uas yuav tsum tau ua los ntawm IEC 60664-1 Kev Kho 3. Daim duab 10 qhia cov duab kos.
Qhov kev tshem tawm yam tsawg kawg nkaus yog qhov kev ncua deb ntawm lub taub hau ntsia hlau thiab hauv qab ntawm PCB yuav tsum muaj qhov deb txaus los tiv thaiv hluav taws xob hauv cheeb tsam no.
Xwb, kev ntsuas rwb thaiv tsev ntxiv, xws li PCB qhov, txheej los yog cov potting tshwj xeeb yuav tsum tau muab coj los ua kom tau raws li qhov tsim nyog clearance thiab creepage deb qauv.

Daim duab 10. Kev tshem tawm ntawm Screw thiab PCB

Hom ntsia hlau txiav txim qhov tsawg kawg nkaus qhov sib txawv ntawm nws thiab PCB. Nrog lub lauj kaub taub hau ntsia hlau raws li ISO7045, lub xauv lub tshuab ntxhua khaub ncaws raws li DIN 127B thiab lub tshuab ntxhua khaub ncaws tiaj tus DIN 125A, thiab clamp uas tau qhia hauv daim duab 10, qhov kev ncua deb yuav yog 4.25 hli. Tej yam clearance thiab creepage yog muaj nyob rau hauv cov ntaub ntawv. Cov ntsiab lus ntxiv ntawm module clearance lossis creepage deb tuaj yeem hu rau daim ntawv thov kev txhawb nqa lossis kev muag khoom thiab kev lag luam.
