IRF640N N-Channel Power MOSFET Transistor 200V 18A 0.15Ω TO-220

Description

IRF640 N-Channel Power MOSFET Transistor 200V 18A 0.15Ω TO-220 The IRF640N is a high-performance N-Channel Power MOSFET from International Rectifier, featuring Fifth Generation HEXFET technology. This transistor is designed to deliver extremely low on-resistance, fast switching speeds, and rugged reliability, making it ideal for a wide range of demanding applications. Encased in a TO-220 package, it offers excellent thermal performance and is easy to mount. With a maximum drain-source voltage of 200V and a continuous drain current of 18A, the IRF640N is perfect for power management in industrial and commercial systems. Features High Voltage Handling : 200 V drain‑to‑source breakdown voltage (V BR DSS). Low On‑Resistance : R DS(on) ≤ 0.15 Ω at V GS =10 V, ID=11 A. High Current Capability : 18 A continuous drain current at T C =25 °C (13 A at 100 °C). Robust Avalanche Rating : Single‑pulse avalanche energy E AS =247 mJ; fully avalanche‑rated design. Fast Switching : Total gate charge Q g =67 nC; turn‑on delay t d(on) =10 ns; turn‑off delay t d(off) =23 ns. High Temperature Operation : Junction temperature range –55 °C to +175 °C. Ease of Paralleling : Simple to parallel multiple devices for higher current requirements. Simple Drive Requirements : Standard gate‑drive levels; no special drive circuitry needed.
