The IRFP460-IR is an International Rectifier N-Channel enhancement-mode power MOSFET housed in the industry-standard TO-247AC through-hole package. Rated for 500V drain-to-source voltage and 20A continuous drain current, it combines a low RDS(on) of approximately 0.27Ω with fast switching characteristics and avalanche energy capability. Designed to meet the rigorous demands of industrial power conversion, this device delivers reliable performance across a wide range of operating temperatures, making it a dependable drop-in solution for both original equipment builds and field-replacement maintenance scenarios.

The IRFP460-IR sees widespread deployment in variable-speed motor drives, switch-mode and resonant power supplies, DC-DC converters, UPS systems, induction heating equipment, and industrial inverters. Its 500V blocking capability and low gate charge make it a practical choice for designers working with rectified European mains or 400V DC bus architectures. Field service engineers frequently specify this device as a direct replacement in legacy industrial drives and power conditioning equipment where minimizing downtime is critical and exact parametric matching to the original design is required.

Quick Reference: IRFP460-IR

Key Features of the IRFP460-IR:

• 500V drain-to-source breakdown voltage (BVDSS) supporting high-voltage bus topologies up to and beyond rectified 240VAC mains
• 20A continuous drain current (TC = 25°C) with 80A pulsed drain current capability for transient load handling
• RDS(on) of 0.27Ω (typical) at VGS = 10V, minimizing conduction losses in continuous-duty switching applications
• Avalanche-rated construction with specified single-pulse and repetitive avalanche energy (EAS / EAR) for robust clamping in inductive-load circuits
• Fast intrinsic body diode with low reverse recovery charge, reducing switching losses in synchronous and bridge converter topologies
• TO-247AC package with isolated mounting tab enables straightforward heatsink integration without additional isolation hardware in most configurations

International Rectifier's IRFP460 series has been a staple of industrial power design for decades, and while Infineon (IR's parent company) continues limited production, procurement teams regularly encounter extended lead times, minimum order quantity constraints, or outright allocation shortages on this part. Legacy equipment running IRFP460-IR devices — particularly older drives and power supplies no longer in active manufacturing support — can face months-long procurement delays through standard distribution channels. ATI Accurate Technology maintains independent stock of the IRFP460-IR specifically to bridge these gaps for MRO buyers and production schedulers who cannot wait.
