Figure 18: Allowable Iav vs. time in avalanche

The previous curve give the safe operating area for unclamped inductive loads, single

pulse or repetitive, under the following conditions:

Where:

To de rate above 25°C, at fixed IAV, the following equation must be applied:

Where:

Zth= K*Rth is the value coming from normalized thermal response at fixed pulse width
