IRF740 MOSFET: N-Ch, 400V, 10A. Full specification with pinout and replacement list

IRF740 Spec and Replacement

The IRF740 is an N-channel MOSFET designed for high-voltage switching applications. It features a maximum drain-source voltage (V_DS) of 400V and a continuous drain current (I_D) of 10A at 25°C. With a low on-resistance (R_DS(on)) of 0.55Ω, it minimizes conduction losses, making it suitable for power supplies, motor drivers, and inverter circuits. The device supports fast switching speeds due to its low gate charge, enabling efficient operation in PWM and high-frequency applications. Its TO-220 package allows effective heat dissipation, while the MOSFET’s high avalanche energy rating ensures robustness under transient conditions. Proper gate drive and thermal management are crucial to maximize performance and reliability in demanding electronic systems.
