1. Sinusoidal pulse of 10 ms duration
2. For variant 03 the “per device” ratings apply only when both cathode terminals are tied together.
3. Pulsed, duration 5 ms, F = 50 Hz
4. For T
case
+110°C,
derate linearly to 0 A at +150°C.
5. For devices with hot solder dip lead finish all testing performed at T
amb
