Product Overview
The IRFP4568PBF is high-performance N-Channel enhancement-mode power MOSFET adopting Infineon HEXFET technology, optimized for high-power high-efficiency switching circuits. It features 150V drain-source breakdown voltage and 171A continuous drain current limited by package. Ultra-low R_DS(on) effectively cuts conduction loss and heat generation under heavy load. It delivers excellent repetitive avalanche resistance and built-in fast recovery body diode with stable dv/dt performance. TO-247AC heavy-duty through-hole package provides outstanding thermal dissipation, widely used in synchronous rectifiers, UPS inverters, EV battery management, high-power DC-DC converters and industrial motor drive systems.
Core Advantages
Ultra-Low Conduction Resistance (R_DS(on))
Ultra-low internal on-resistance reduces I²R thermal loss under high continuous load and improves overall power conversion efficiency of equipment.
Outstanding Avalanche and Dynamic Ruggedness
100% factory tested for repetitive avalanche energy and high dv/dt transient tolerance, protecting circuits from inductive voltage surge damage.
Exceptional High-Current Capabilities
Supports up to 171A continuous drain current limited by TO-247AC package, stable for high inrush load of industrial motor and heavy power switching equipment.
High Thermal Capacity TO-247AC Package
3-pin through-hole power package with low junction-to-case thermal resistance, easy to fix on large heat sinks for long-term high-current stable operation.

Frequently Asked Questions
Q1: Is your currently available stock of the IRFP4568PBF power transistor 100% genuine and factory-original?
A: Yes, all IRFP4568PBF in stock are brand-new original Infineon components. All batches are stored under ESD anti-static protection and packed in factory tubes or original cartons.
Q2: Why is the continuous current rating listed as 171A if the silicon die can handle more theoretically?
A: The 171A continuous limit is defined by TO-247AC package wire bonds and pins, not the silicon die, to guarantee long-term stable operation without overheating damage.
Q3: What exact manufacturing specification does the “PBF” suffix verify on this component label?
A: PBF stands for 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 development division obtain physical step files, thermal simulation profiles, or ask for special volume pricing tiers?
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.
