IRF9640 P-Channel Power MOSFET Transistor 200V 11A TO-220
The IRF9640 is a P-channel power MOSFET engineered for commercial and industrial power applications. Housed in the TO-220AB package, it offers a 200 V drain-to-source rating and is optimized for fast switching and rugged operation. Its third-generation silicon process provides a balance of low on-resistance, switching performance and avalanche robustness suitable for medium-power designs.
Electrically the device supports up to −11 A continuous drain current (TC = 25 °C) with pulsed capability far higher for short durations, and has an RDS(on) of 0.50 Ω measured at VGS = −10 V (ID = −6.6 A). The IRF9640 includes a well-characterized body diode and is rated for repetitive avalanche and high dV/dt performance, making it tolerant to inductive switching stresses when used within SOA limits.
Mechanically the TO-220AB offers low thermal resistance for heatsinking (RθJC ≈ 1.0 °C/W) and the datasheet provides thermal, SOA and switching graphs to guide reliable implementation. Available as Pb-free and SnPb part numbers, the IRF9640 is commonly used where a high-voltage P-channel device is required for high-side switching, complementary stages, or general power management in industrial equipment.
