LNK302/304-306
ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage ..................................................-0.3Vto700V Notes:
PeakDRAINCurrent(LNK302).................200mA(375 mA)(2) 1. All voltages referenced to SOURCE, TA = 25 °C.
PeakDRAINCurrent(LNK304).................400mA(750 mA)(2) 2. The higher peak DRAIN current is allowed if the DRAIN
PeakDRAINCurrent(LNK305).................800mA(1500 mA)(2)
to SOURCE voltage does not exceed 400 V.
PeakDRAINCurrent(LNK306).................1400mA(2600 mA)(2) 3. Normally limited by internal circuitry.
FEEDBACK Voltage .........................................-0.3 V to 9 V 4. 1/16 in. from case for 5 seconds.
FEEDBACK Current.............................................100 mA 5. Maximum ratings specified may be applied, one at a time,
BYPASS Voltage ..........................................-0.3 V to 9 V
StorageTemperature..........................................-65°C to150°C
OperatingJunctionTemperature(3) .....................-40°C to150°C
Lead Temperature(4) ........................................................260 °C
without causing permanent damage to the product.
Exposure to Absolute Maximum Rating conditions for
extended periods of time may affect product reliability.
