ABSOLUTE MAXIMUM RATINGS(1,6)
DRAIN Voltage ..................................................700 V Notes:
PeakDRAINCurrent...................................200mA(375 mA)(2) 1. All voltages referenced to SOURCE, TA = 25 °C.
Peak Negative Pulsed Drain Current (see Fig. 11) ...100 mA(3) 2. The higher peak DRAIN current is allowed while the
FEEDBACK Voltage .........................................-0.3 V to 9 V
DRAIN voltage is simultaneously less than 400 V.
FEEDBACK Current.............................................100 mA 3. Duration not to exceed 2 μs.
BYPASS Voltage ..........................................-0.3 V to 9 V 4. Normally limited by internal circuitry.
StorageTemperature..........................................-65°C to150°C 5. 1/16 in. from case for 5 seconds.
OperatingJunctionTemperature(4) .....................-40°C to150°C 6. Maximum ratings specified may be applied, one at a time,
Lead Temperature(5) ........................................................260 °C
without causing permanent damage to the product.
Exposure to Absolute Maximum Rating conditions for
extended periods of time may affect product reliability.
