InnoSwitch3-MX Absolute Maximum Ratings1,2
D Pin Voltage: INN346x ... -0.3 V to 650 V Notes: D Pin Voltage: INN3475/3476/3477/3474 .. -1.3 V to 725 V 1. All voltages referenced to SOURCE and Secondary GROUND, DRAIN Pin Peak Current: INN34x4 .. 1.52 A (2.85 A)3 T = 25 °C. A INN34x5 .. 1.84 A (3.45 A)3 2. Maximum ratings specified may be applied one at a time without INN34x6 .. 2.32 A (4.35 A)3 causing permanent damage to the product. Exposure to Absolute INN34x7 .. 2.64 A (4.95 A)3 Maximum Ratings conditions for extended periods of time may INN3468 .. 2.96 A (5.55 A)3 affect product reliability. V Pin Voltage .. -0.3 V to 725 V 3. Higher peak Drain current is al owed while the Drain voltage is FW Pin Voltage .. 250 V simultaneously less than 400 V. SR Pin Voltage ..-0.3 V to 6 V 4. Normal y limited by internal circuitry. VOUT PIN Voltage ...-0.3 V to 25 V 5. Absolute maximum single pulse. BPP/BPS Pin Voltage ... -0.3 V to 6 V Operating Junction Temperature4 ...-40 °C to 150 °C Ambient Temperature..-40 °C to 105 °C
