Electrical characteristics
9/18
The previous curve gives the safe operating area for unclamped inductive loads, single
pulse or repetitive, under the following conditions:
PD(AVE) = 0.5 * (1.3 * BVDSS * IAV)
EAS(AR) = PD(AVE) * tAV
Where:
IAV is the allowable current in avalanche
PD(AVE) is the average power dissipation in avalanche (single pulse)
tAV is the time in avalanche
To derate above 25 °C, at fixed IAV , the following equation must be applied:
IAV = 2 * (Tjmax - TCASE)/ (1.3 * BVDSS * Zth)
Where:
Zth = K * Rth is the value coming from normalized thermal response at fixed pulse width
equal to TAV .
