ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage .................................................. -0.3 V to 700 V Notes:
Peak DRAIN Current......................................400 mA (750 mA)(2) 1. All voltages referenced to SOURCE, TA = 25 °C.
FEEDBACK Voltage ................................................ -0.3 V to 9 V 2. The higher peak DRAIN current is allowed while the
FEEDBACK Current .................................................... 100 mA DRAIN voltage is less than 400 V.
BYPASS Voltage...................................................... -0.3 V to 9 V 3. Normally limited by internal circuitry.
Storage Temperature .......................................... -65 °C to 150 °C 4. 1/16 in. from case for 5 seconds.
Operating Junction Temperature(3) ..................... -40 °C to 150 °C 5. Maximum ratings specified may be applied, one at a time,
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.
THERMAL IMPEDANCE
Thermal Impedance: P or G Package:
(θJA) ........................... 70 °C/W(2); 60 °C/W(3)
(θJC)(1) ............................................... 11 °C/W
Notes:
1. Measured on pin 2 (SOURCE) close to plastic interface.
2. Soldered to 0.36 sq. in. (232 mm2), 2 oz. (610 g/m2) copper clad.
3. Soldered to 1 sq. in. (645 mm2), 2 oz. (610 g/m2) copper clad.
