Product Overview
The IRFP4310ZPBF is industrial-grade N-Channel enhancement-mode power MOSFET adopting Infineon HEXFET technology. Optimized for high-density high-current switching, it features 100V drain-source voltage and 120A continuous drain capacity. Ultra-low R_DS(on) cuts conduction loss and heat generation. It has excellent avalanche resistance and built-in fast recovery body diode with low reverse recovery charge, resisting high-frequency voltage surges without latch-up. TO-247AC through-hole package delivers outstanding heat dissipation, widely used in high-efficiency SMPS, DC motor drives, battery management, synchronous rectifier and solar inverter systems.
Core Advantages
Ultra-Low Conduction Resistance (R_DS(on))
Extremely low internal on-resistance reduces I²R heat loss under heavy continuous load and improves overall power conversion efficiency.
Exceptional Dynamic and Avalanche Ruggedness
100% factory tested for repetitive avalanche energy and high dv/dt transient tolerance, protecting circuits from inductive voltage spikes.
Optimized High-Current Handling
Supports up to 120A continuous drain current limited by package, ideal for high-inrush load in motor drives and industrial switching equipment.
High Thermal Performance TO-247AC Frame
3-pin through-hole power package with low junction-to-case thermal resistance, easy to mount on large heat sinks for stable high-current operation.

Frequently Asked Questions
Q1: Is your currently available stock of the IRFP4310ZPBF power transistor 100% genuine and factory-original?
A: Yes, all IRFP4310ZPBF 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: What do the specific “Z” and “PBF” characters designate in this part number profile?
A: The “Z” stands for low on-resistance design with enhanced avalanche energy compared to standard versions. The “PBF” suffix means lead-free, fully compliant with RoHS environmental regulations.
Q3: Why is the continuous current rating listed as 120A if the internal silicon die may technically support more?
A: The 120A limit is defined by TO-247AC package wire bonds and pins, not the die, to guarantee long-term stable operation without overheating damage.
Q4: How can our technical division request thermal simulation models, step files, 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.
