IRFP460 Pinout, Equivalent, Application, Datasheet

Before integrating this device into high-voltage converters, induction heating circuits, or SMPS power stages, it is essential to understand the IRFP460 pinout, as correct Gate, Drain, and Source identification ensures safe wiring and reliable switching performance. The IRFP460 is a high-voltage, high-power N-Channel MOSFET commonly used in industrial supplies, motor drives, UPS systems, and high-frequency inverters due to its strong current capability and durable TO-247 package.

Introduction to IRFP460 N-Channel MOSFET

The IRFP460 is a rugged N-channel enhancement MOSFET designed for high-voltage and high-power switching applications. With a 500V VDS rating and 20A continuous drain current, it is ideal for SMPS applications, power inverters, motor controllers, and industrial high-frequency circuits. Its 250W total power dissipation and durable TO-247 casing allow it to operate under heavy thermal loads. Although its RDS(on) of 0.27Ω is higher compared to modern MOSFETs, its robustness and reliability make it a preferred component in demanding power electronics environments.
