Product details
Overview
IRFB4115GPBF from Infineon Technologies (formerly International Rectifier) is a 150V, 104A N-channel enhancement-mode HEXFET Power MOSFET in TO-220AB package, optimized for high-efficiency synchronous rectification and hard-switched SMPS topologies. It delivers 9.3mΩ typical RDS(on), 77nC total gate charge, and enhanced body diode dV/dt/dI/dt ruggedness for UPS and telecom power systems.
For engineers reviewing the IRFB4115GPBF datasheet, IRFB4115GPBF pinout, IRFB4115GPBF application, or IRFB4115GPBF equivalent, key selection criteria include its 150V VDSS, 104A continuous drain rating at 25°C, 0.40°C/W junction-to-case thermal resistance, avalanche energy rating of 220mJ, and SOA compliance up to 10ms at 50V.
Technical Context
This MOSFET employs planar silicon process with optimized cell layout to achieve low RDS(on) while maintaining robust unclamped inductive switching capability. Its body diode exhibits 86ns reverse recovery time and 300nC Qrr at 25°C, enabling reliable operation in synchronous buck converters.
The device features fully characterized dynamic parameters including 5270pF Ciss, 490pF Coss, and 105pF Crss, with gate threshold voltage tightly specified between 3.0–5.0V and transconductance of 97S typical - supporting stable PWM control across industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 150V - Maximum blocking voltage before avalanche onset; enables use in 48V–100V bus applications. |
| RDS(on) typ. | 9.3mΩ @ VGS = 10V, TJ = 25°C - Low conduction loss supports >95% efficiency in 100A-class power stages. |
| ID cont. | 104A @ TC = 25°C - High current handling with TO-220AB package and 0.40°C/W RθJC. |
| Qg | 77nC max - Enables fast switching with moderate gate drive strength; reduces turn-on losses in high-frequency designs. |
| EAS | 220mJ single-pulse - Confirmed avalanche energy rating allows safe operation under inductive fault conditions without snubbers. |
| trr | 86ns @ TJ = 25°C, IF = 62A - Fast body diode recovery minimizes cross-conduction loss in synchronous rectifiers. |
| RθJC | 0.40°C/W - Enables direct heatsink mounting with predictable thermal performance in conduction-limited designs. |
Pinout & Package
IRFB4115GPBF uses the standard TO-220AB package with three leads: Gate (G), Drain (D), and Source (S). The metal tab is electrically connected to the Drain terminal and must be isolated from heatsink unless circuit topology permits common-drain configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control input requiring ≥10V to fully enhance; internal gate resistance is 2.3Ω - affects gate drive loop stability. |
| D | Drain | Main high-side power terminal; connected to metal tab - requires electrical isolation when mounted to heatsink. |
| S | Source | Power return path and reference for gate drive; body diode anode is internally tied to Source. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced avalanche ruggedness | 220mJ single-pulse EAS with validated thermal failure model - eliminates need for external clamping in many UPS and motor drive circuits. |
| Optimized body diode dV/dt immunity | Rated for 2.5V/ns peak diode recovery dv/dt - prevents false turn-on during hard commutation in bridge configurations. |
| Low Coss effective capacitance | 460pF Coss(ER) - reduces switching loss during zero-voltage transition and improves light-load efficiency in resonant topologies. |
| Halogen-free & lead-free | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 - suitable for reflow assembly without baking. |
| Characterized SOA curves | Full Safe Operating Area defined up to 10ms pulse width - enables reliable design margining for overload and short-circuit protection. |
Applications
| Telecom DC-DC Converters | Uninterruptible Power Supplies (UPS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current 150V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP110N15M5 | 150V, 110A, 8.5mΩ RDS(on), but only 180mJ EAS and no published Coss(ER) data. | Lacks validated avalanche SOA curves beyond 100µs - unsuitable for unclamped inductive loads above 50A. | Prefer for cost-sensitive, non-avalanche-critical 150V SMPS where lower RDS(on) outweighs ruggedness needs. |
| IXTH110N15L2 | 150V, 110A, 9.0mΩ RDS(on), 250mJ EAS, but TO-247 package increases board area and thermal interface complexity. | Higher gate charge (95nC) demands stronger gate driver; superior avalanche rating suits industrial motor drives. | Choose when system-level reliability under fault conditions justifies larger footprint and higher drive power. |
Compared with STP110N15M5 and IXTH110N15L2, IRFB4115GPBF offers optimal balance of TO-220AB manufacturability, 220mJ avalanche margin, and 77nC gate charge - making it preferred for space-constrained, high-reliability 150V power stages where thermal management and fault tolerance are co-prioritized.

FAQ
Is IRFB4115GPBF suitable for surface-mount assembly?
No - the TO-220AB package is explicitly not recommended for surface-mount applications per the datasheet. It requires through-hole mounting with mechanical screw attachment (6-32 or M3) and thermal interface material to a heatsink. SMT alternatives like D2PAK or LFPAK packages would be required for reflow assembly.
What is the maximum allowable gate-to-source voltage for reliable operation?
The absolute maximum VGS is ±20V, but the device is characterized for stable operation at 10V - the typical gate drive level for full enhancement. Exceeding 15V risks accelerated gate oxide degradation; gate drive circuits should include clamping to limit transient overshoot to ≤12V.
How does the body diode performance compare to discrete Schottky rectifiers?
The integrated body diode has VSD = 1.3V and trr = 86ns - higher forward drop and slower recovery than Schottky diodes, but sufficient for synchronous rectification in 100–500kHz SMPS where gate timing controls conduction. It eliminates external diode count but requires careful dead-time optimization to avoid shoot-through.
Can IRFB4115GPBF replace older IRFB4115PBF variants?
Yes - IRFB4115GPBF is the lead-free, halogen-free qualified successor to IRFB4115PBF, with identical electrical specifications, pinout, and thermal performance. The "G" suffix denotes green compliance; no design changes or derating are required for drop-in replacement in existing layouts.
