8 / 16 page LNK362-364 C 12/05 8 ABSOLUTE MAXIMUM RATINGS(1,5) DRAIN Voltage .................................. .............-0.3 V to 700 V Peak DRAIN Current: LNK362................200 mA (375 mA)(2) LNK363/364.........400 mA (750 mA)(2) FEEDBACK Voltage ...........................................-0.3 V to 9 V FEEDBACK Current ...................................................100 mA BYPASS Voltage.................................................. -0.3 V to 9 V Storage Temperature .....................................-65 °C to 150 °C Operating Junction Temperature(3) ................-40 °C to 150 °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 while the DRAIN voltage is simultaneously 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. THERMAL IMPEDANCE Thermal Impedance: P or G Package: ( θ JA) ........................... 70 °C/W (2); 60 °C/W(3) ( θ JC) (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.
