Notes:
1. All voltages referenced to SOURCE, TJ = 25 °C.
2. Normally limited by internal circuitry.
3. 1/16 in. (1.59 mm) from case for 5 seconds.
4. The higher peak DRAIN current is allowed while the DRAIN
voltage is simultaneously less than 400 V.
5. Maximum ratings specified may be applied one at a time,
without causing permanent damage to the product.
Exposure to Absolute Rating conditions for extended periods
of time may affect product reliability.
