Product Overview
The IRFP4768PBF is N-Channel enhancement-mode HEXFET power MOSFET designed by Infineon for medium-high voltage power conversion. Rated at 250V drain-source voltage and 93A continuous drain current, it features controlled 17.5mΩ on-resistance to balance loss and voltage withstand capability. It has built-in fast recovery body diode and high repetitive avalanche energy to resist high voltage spikes. TO-247AC robust package delivers reliable heat dissipation, widely used in high voltage SMPS, solar converters, UPS inverters and industrial power switching equipment.
Core Advantages
Balanced On-Resistance & 250V Withstand Voltage
Optimized cell design supports up to 250V operating voltage with moderate conduction loss, perfect for medium-high voltage power supply topologies.
High Avalanche Ruggedness
100% factory tested for repetitive avalanche energy, effectively protects circuits from inductive voltage surge damage.
93A Continuous Current Capacity
Package-limited 93A continuous drain current handles heavy load for industrial power conversion and energy storage systems.
TO-247AC Thermal Optimized Package
3-lead through-hole power package with low thermal resistance, easy mounting on external heat sinks for stable long-hour operation.

Frequently Asked Questions
Q1: Is your IRFP4768PBF original Infineon genuine stock?
A: Yes, all IRFP4768PBF are brand new original Infineon components, stored under ESD anti-static protection with factory tube packaging.
Q2: Why continuous current is limited to 93A instead of higher?
A: The 93A rating is limited by TO-247AC package wire bonds, not silicon die, to guarantee long-term safe operation without overheating.
Q3: What does PBF suffix stand for?
A: PBF means lead-free matte tin terminals, fully compliant with RoHS environmental regulations.
Q4: Can I get PCB footprint, 3D step files and volume discount?
A: Submit inquiry with your project info, our technical team will send all related technical documents and bulk price offer within 24 hours.
