IRF840
The IRF840 is a high-voltage N-Channel MOSFET designed for reliable switching in power electronics applications. With a drain-source voltage rating of 500 V and a continuous drain current of 8 A, it is suitable for switch-mode power supplies (SMPS), DC-AC converters, industrial motor drivers, and audio amplifiers. Manufactured by Vishay and STMicroelectronics, it provides consistent performance for industrial and commercial systems.
Featuring a low on-resistance of 0.85 Ω and a fast rise time of 23 ns, the IRF840 reduces power loss and supports high-frequency operation. Its TO-220 package allows effective thermal dissipation and easy integration with heatsinks, supporting stability under demanding operating conditions. The device is avalanche-rated and has a low gate charge of 63 nC, making it suitable for inverter circuits, automation systems, and solid-state relays.
The IRF840 operates across a wide temperature range (−55 °C to +150 °C) and offers reliable switching characteristics for renewable energy systems, UPS applications, and motor control circuits. Its design ensures stable operation in industrial, telecom, and consumer electronics environments.
