IRF740 400V 10A N-Channel MOSFET

IRF740 400V 10A Power N-Channel MOSFET – TO-220

IRF740 is a 400V N-Channel power MOSFET designed for high-voltage and high-frequency switching in power electronics. With a continuous drain current of 10A and low on-resistance of 0.55Ω at VGS=10V, it ensures efficient power transfer and reduced energy losses.

Encased in a durable TO-220 package, the IRF740 offers strong thermal performance, supporting the use of heatsinks for effective heat dissipation. It operates within a temperature range of -55°C to +150°C, making it reliable for demanding applications such as motor drives, DC-DC converters, and UPS systems.

With fast switching speeds (rise time of 27ns and fall time of 24ns), the IRF740 is ideal for high-frequency circuits, including inverters, LED drivers, and battery management systems. It supports pulsed drain currents up to 40A, making it suitable for transient loads in motor control and solenoid drivers.

The IRF740’s high voltage tolerance and robust construction make it a preferred choice for industrial automation, renewable energy systems, and audio amplifiers. Its design provides dependable operation in both consumer and industrial electronic applications.
