Notes:
1. All voltages referenced to SOURCE, T
A
= 25
°C.
2. The higher peak DRAIN current is allowed while the
DRAIN voltage is simultaneously less than 400 V.
3. Duration not to exceed 2
μs.
4. Normally limited by internal circuitry.
5. 1/16 in. from case for 5 seconds.
6. Maximum ratings specified may be applied, one at a time,
without causing permanent damage to the product.
Exposure to Absolute Maximum Rating conditions for
extended periods of time may affect product reliability.
