Product Overview
The IRFP4868PBF is an industrial-grade high-performance N-channel enhancement power MOSFET built on Infineon’s robust StrongIRFET™ process platform. Designed for high-voltage power topologies with superior power density and long-term reliability, this device features a 300V drain-source breakdown voltage and a maximum continuous drain current of 70A. Its core design minimizes static Rds(on) conduction loss to reduce heat generation under sustained heavy load operation. The device integrates reinforced gate oxide protection, high repetitive avalanche energy tolerance, and an integrated fast-recovery body diode with low reverse recovery charge Qrr to suppress inductive switching voltage spikes. Packaged in thermally optimized standard TO-247AC through-hole housing, it serves as a reliable power switch for SMPS, motor inverters, UPS, high-voltage DC-DC converters and industrial automation power stages.
Core Advantages
Optimized High-Voltage Performance Matrix
The 300V rated breakdown voltage matches high continuous current capacity, providing sufficient voltage margin for high-voltage DC bus circuits and heavy industrial switching systems.
Ultra-Low Conduction Loss (Rds(on))
This 300V-class MOSFET achieves very low drain-source on-resistance, cutting I²R power loss and improving overall conversion efficiency under full thermal load conditions.
Advanced StrongIRFET™ Structural Ruggedness
Fully tested for repetitive avalanche energy (Eas) and high dv/dt transient immunity, greatly improving system stability against line surges and inductive kickback voltage pulses.
High-Efficiency TO-247AC Thermal Transfer
The 3-pin through-hole package delivers low junction-to-case thermal resistance RθJC, supporting easy mechanical mounting to large heat sinks or forced-cooling radiators.
