Product Overview
The IRFP460PBF is a widely used N-Channel enhancement-mode power MOSFET from Vishay Siliconix. Optimized cell structure delivers stable switching performance, reliable heat dissipation and low application cost. Rated 500V drain-source voltage and 20A continuous drain current, it withstands heavy electrical stress for industrial power equipment. Optimized gate oxide simplifies gate drive circuit design, and high repetitive avalanche energy provides surge protection against inductive voltage spikes. The TO-247AC through-hole package features low thermal resistance, ideal for SMPS, UPS, industrial converters and motor drive systems.
Core Advantages
Industry-Standard Rugged Design
Stable monolithic chip structure ensures long service life and consistent performance under harsh working conditions, reducing equipment failure rates.
Superb Avalanche Stress Safety Factors
100% factory tested for single and repetitive avalanche energy tolerance, automatically releasing energy generated by inductive voltage kickbacks.
Optimized High-Voltage Performance Matrix
500V rated breakdown voltage matches mainstream 220V/380V AC-DC conversion topologies, with sufficient current margin for heavy load operation.
Low Thermal Resistance Package
TO-247AC through-hole housing enables efficient heat transfer to external heat sinks, maintaining stable temperature under long-term high-current operation.

Frequently Asked Questions
Q1: Is your currently available stock of the IRFP460PBF power transistor 100% genuine and original?
A: Yes, all IRFP460PBF in stock are brand-new original Vishay Siliconix components. All batches are stored under ESD anti-static protection and packed in factory tubes or original cartons.
Q2: What is the main structural or electrical performance distinction between the IRFP460PBF and the IRFP460LCPBF?
A: Both share identical 500V/20A ratings and TO-247AC package. The “LC” suffix of IRFP460LCPBF stands for Low Charge; it features lower total gate charge for faster switching and reduced gate drive loss, while standard IRFP460PBF has higher Qg for cost-sensitive common power circuits.
Q3: What exact manufacturing specification does the “PBF” suffix verify on this component label?
A: PBF means Pb-Free. Component pins adopt matte tin plating, fully compliant with global RoHS standards for all mainstream electronic assembly lines.
Q4: How can our engineering division obtain thermal simulation models, application design guides, or high-volume wholesale pricing schedules?
A: Fill out the Quick Inquiry form with your project parameters. Our technical team will send complete technical documents and bulk quotations within 24 hours.
