VISHAY IRF740APBF Power MOSFET N-Channel 400V 10A TO-220AB

The VISHAY IRF740APBF is a robust 400V N-channel Power MOSFET, engineered for high-speed power switching and demanding applications. Its low gate charge (Qg) simplifies drive requirements, making it an efficient and reliable choice for switch-mode power supply (SMPS) designs and other hard-switching circuits that operate at high frequencies.

This MOSFET features enhanced ruggedness, with improvements in gate handling, avalanche energy tolerance, and dynamic dv/dt capability, ensuring stable performance under stressful conditions. It is fully characterised for capacitance, avalanche voltage, and current, providing designers with reliable data for circuit optimisation. A key benefit is the low drain-source on-state resistance (Rds(on)) of 0.55 ohms, which minimises conduction losses and improves overall system efficiency.

Key Specifications & Features
