请教各位老师,有两款Power MOSFET,它们的‘单脉冲雪崩能量’参数值标示为A管= 90 mJ;B管= 390 mJ。
但A、B两管的测试条件不同,该如何判断哪一款的‘单脉冲雪崩能量’参数好一点?请指点一二为盼!
参数标示值如下:
---------------------------------------------------------------
MOSFET A:
Test Condition : Starting TJ = 25°C, L = 0.2mH, IAS = 30A.
Symbol Parameter Value Unit
EAS Single Pulse Avalanche Energy 90 mJ
---------------------------------------------------------------
MOSFET B:
Test Condition : Starting TJ = 25°C, L = 7.8mH, IAS = 10A.
Symbol Parameter Value Unit
EAS Single Pulse Avalanche Energy 390 mJ
