Fig. 1: Non repetitive surge peak on-state current

versus overload duration (Tj initial=25°C).

Fig. 2: Relative variation of holding current versus

junction temperature.

Fig. 3: Relative variation of junction capacitance

versus reverse applied voltage(typical values).

Note: For VRM upper than 56V, the curve is

extrapolated(dotted line).

Fig. 4: On-state voltage versus on-state current

(typical values).
