ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage ..................................................-0.3Vto700V
Peak DRAIN Current (LNK302).................200 mA(375 mA)(2)
Peak DRAIN Current (LNK304).................400 mA(750 mA)(2)
PeakDRAINCurrent(LNK305).................800mA(1500 mA)(2)
PeakDRAINCurrent(LNK306).................1400mA(2600 mA)(2)
FEEDBACK Voltage .........................................-0.3 V to 9 V
FEEDBACK Current.............................................100 mA
BYPASS Voltage ..........................................-0.3 V to 9 V
StorageTemperature..........................................-65°C to150°C
OperatingJunctionTemperature(3).....................-40°C to150°C
Lead Temperature(4) ........................................................260 °C
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 in. from case for 5 seconds.
5. Maximum ratings specied 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.
