Demystifying the IRFP460 An Expert’s Guide
The IRFP460 is a high-resistance, high-power MOSFET with an N-channel interface that has become a popular choice for complex electronics projects, such as switch-mode power supplies (SMPS), inverters, motor drivers, and RF amplifiers. Known for its durability, efficiency, and high voltage rating, this device helps engineers design reliable, efficient, and affordable systems.
In this expert guide, we take an in-depth look at the IRFP460’s basic features, usage, common applications, and best practices. We will also show you how to harness power through MOSFETs, IGBTs, and semiconductor solutions from DRex Electronics, your trusted global components partner.
🔍What is IRFP460?
The IRFP460 is an N-channel MOSFET designed to handle high voltages (up to 500 V) and medium currents (up to 20 A), making it ideal for medium and high power circuits. Faster switching and lower gate charge improve overall system efficiency and reduce power consumption.

🧪 How Does the IRFP460 Work?
The IRFP460 operates as a voltage-controlled switch:
Gate voltage > threshold (~4V): Turns ON, allowing current flow from drain to source.
Gate voltage < threshold: Stays OFF, blocking current.
With its high breakdown voltage (500V) and low on-resistance, the IRFP460 is ideal for switching high voltages at high speeds while minimizing power loss.
