Key Features
- 100 V drain-source breakdown voltage with 2.2 A continuous drain current for versatile power switching applications
- Low on-resistance of 0.2 Ω maximum minimizes conduction losses and improves overall circuit efficiency
- Compact SOT-223 surface-mount package (JEDEC TO-261AA) ideal for space-constrained PCB designs
- Built-in body diode enables freewheeling operation in inductive switching and motor-drive circuits without additional diode
Applications
The IRFL4310PBF is well-suited for load switching, DC-DC converter synchronous rectification, and motor drive applications requiring a compact 100 V N-channel MOSFET. Its SOT-223 package and low 0.2 Ω on-resistance make it a practical choice for industrial power management modules, battery protection circuits, and low-power inverter designs where board space and switching efficiency are both critical constraints.

Frequently Asked Questions
What are the drain voltage and current ratings of the IRFL4310PBF?
The IRFL4310PBF is rated for a 100 V drain-source breakdown voltage and a continuous drain current (ID) of 2.2 A at room temperature, with a maximum pulsed rating higher. Its 0.2 Ω maximum on-resistance (RDS(on)) limits conduction losses in applications up to approximately 100 V bus voltage.
Which PCB footprint does the IRFL4310PBF use, and how does the SOT-223 package simplify heat management?
The IRFL4310PBF comes in a 4-pin SOT-223 package (JEDEC TO-261AA / JESD-30 R-PSSO-G3) with the drain connected to the large exposed tab. This tab acts as a heat spreader, transferring heat directly into PCB copper pours or thermal vias, providing better thermal performance than a standard SOT-23 MOSFET of equivalent die size.
When is the IRFL4310PBF preferred over a TO-220 MOSFET at 100 V?
When a design demands a surface-mount 100 V N-channel MOSFET with currents up to 2.2 A, the SOT-223-packaged IRFL4310PBF is preferred over bulkier TO-220 through-hole alternatives. It enables automated SMT assembly, reduces PCB height, and the exposed drain tab still allows adequate heat dissipation for loads up to roughly 2 A continuous without an external heatsink.
Does the IRFL4310PBF include a body diode, and how does that affect inductive load switching?
Yes, the IRFL4310PBF includes a built-in anti-parallel body diode inherent to MOSFET construction. This diode provides freewheeling current paths in inductive load switching applications such as relay drivers, solenoid controls, and low-power motor drives, eliminating the need for a separate external flyback diode in many designs.
