Hi guys,
I am using PNP Power transistors (darlington), BDX34C- ST Micro, In my design, which are working in active mode region.. providing or passing 2.5A thorugh each transistor. Those are configured as constant current source for 10A using 4 transistors (2.5A each). This constant current source works during 50% on cycle of an 100Hz square wave frequency i receive as input. During off cycle transistor remain off.
I need to know the maximum possible reasons for transistor failure, whether it be juntion temp, Vce voltage etc.
Kindly suggest what parameters can make my working transistor fail (short circuit).
