DRAIN Voltage ..................................................-0.3Vto700V

FEEDBACKVoltage................................................-0.3Vto9V

FEEDBACK Current .................................................... 100 mA

BYPASSVoltage......................................................-0.3Vto9V

StorageTemperature..........................................-65°C to150°C

Notes:

1. All voltages referenced to SOURCE, T

2. The higher peak DRAIN current is allowed while the

DRAIN voltage is less than 400 V.

3. Normally limited by internal circuitry.

4. 1/16 in. 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.
