Notes:
1. All voltages referenced to SOURCE, T
A = 25 °C.
2. The higher peak DRAIN current is allowed if the DRAIN to
SOURCE voltage does not exceed 400 V.
3. Normally limited by internal circuitry.
4. 1/16” from case for 5 seconds.
5. 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.
