Notes:

1. All voltages referenced to SOURCE, T

J = 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.
