FORWARD BIAS

The Forward Bias Safe Operating Area represents the

voltage and current conditions these devices can withstand

during forward bias. The data is based on TC = 25_C; TJ(pk)

is variable depending on power level. Second breakdown

pulse limits are valid for duty cycles to 10%, and must be der-

ated thermally for TC > 25_C.

REVERSE BIAS

The Reverse Bias Safe Operating Area represents the

voltage and current conditions these devices can withstand

during reverse biased turn–off. This rating is verified under

clamped conditions so the device is never subjected to an

avalanche mode.
