Product details
Overview
IRF7455PBF from Infineon Technologies (formerly International Rectifier) is a 30V, 8.9A, N-channel logic-level MOSFET in SO-8 package with RDS(on) = 22 mΩ @ VGS = 10V and 32 mΩ @ VGS = 4.5V, optimized for high-efficiency DC-DC converters and load switching in consumer power management.
For engineers reviewing the IRF7455PBF datasheet, IRF7455PBF pinout, IRF7455PBF application, or IRF7455PBF equivalent, key selection criteria include gate threshold voltage (VGS(th) = 1.0–2.4V), low gate charge (Qg = 12 nC), and SO-8 thermal performance for board-level power density constraints.
Technical Context
This MOSFET uses TrenchMOS technology to achieve enhanced conduction efficiency and fast switching response. Its logic-level gate drive enables direct interfacing with 3.3V/5V microcontrollers without level-shifting circuitry.
The device features integrated ESD protection (HBM > 2kV), specified for operation from –55°C to +175°C junction temperature, and supports synchronous rectification in buck converters where low RDS(on) and controlled Qgd/Qgs ratio reduce switching losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - maximum drain-source blocking voltage for 12V input rail applications |
| ID (continuous) | 8.9 A @ TC = 100°C - sustained current capability with SO-8 heatsinking on 1-in² 2-oz copper |
| RDS(on) | 32 mΩ @ VGS = 4.5V - enables efficient 5V-gate-driven load switch operation |
| Qg | 12 nC - reduces gate driver power loss and enables <500 kHz PWM operation |
| VGS(th) | 1.0–2.4 V - ensures reliable turn-on with standard logic-level outputs |
| PD | 2.5 W @ TA = 25°C - defines ambient-limited power dissipation in non-heatsinked PCB layouts |
Pinout & Package
IRF7455PBF is housed in a standard SO-8 surface-mount package per JEDEC MS-012AA, with exposed drain pad for thermal enhancement and dual-source/drain configuration supporting high-current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source connection for internal parallel FET cells; tied to PCB ground plane for low-inductance return path |
| 4 | Gate | Control terminal requiring ≤12 nC charge for full enhancement; sensitive to ESD but compatible with 3.3V logic |
| 5, 6, 7, 8 | Drain | Power output node connected to exposed thermal pad; carries full load current and serves as primary heat transfer interface |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 4.5V, eliminating need for gate boosters in 5V systems |
| Low RDS(on) × Qg figure of merit | 0.38 Ω·nC - balances conduction and switching loss for high-frequency DC-DC stages |
| Thermally enhanced SO-8 | Exposed drain pad improves θJA by ~25% vs. standard SO-8, enabling higher continuous current |
| RoHS-compliant & lead-free | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1), suitable for standard reflow profiles |
Applications
| USB Power Delivery Switch | Point-of-Load Converter |
|---|---|
Use Scenario: Bidirectional 5–20V USB PD power path control with overcurrent protection. IC Role / Device Role / Timing Role: High-side load switch managing VBUS enable/disconnect under MCU command. Use Value: 32 mΩ RDS(on) limits voltage drop to <160 mV at 5A, preserving PD compliance margins. | Use Scenario: 12V-to-3.3V synchronous buck converter in set-top box mainboard. IC Role / Device Role / Timing Role: Lower-side synchronous rectifier replacing Schottky diode. Use Value: Reduces conduction loss by 65% vs. 40V/5A Schottky, improving full-load efficiency from 87% to 92%. |
| Smartphone Battery Protection | LED Backlight Dimming |
Use Scenario: Primary discharge path switch in battery protection IC subsystem. IC Role / Device Role / Timing Role: Low-threshold N-channel switch controlled by protection ASIC's gate driver output. Use Value: 1.0–2.4V VGS(th) ensures clean turn-on even during brown-out conditions down to 2.8V supply. | Use Scenario: PWM-controlled current sink for white LED strings in LCD TV backlight. IC Role / Device Role / Timing Role: Constant-current switch modulating average LED current at 1–20 kHz. Use Value: 12 nC Qg supports sharp PWM edges with minimal gate drive power, reducing thermal stress on driver IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NTMFS4C06NT1G | RDS(on) = 20 mΩ @ 4.5V, Qg = 14.5 nC, same SO-8 package | Slightly lower RDS(on) but higher gate charge increases driver loss at >1 MHz | Preferred for ultra-low-loss 12V input converters where gate drive capability permits |
| Vishay SI7850DP-T1-GE3 | RDS(on) = 35 mΩ @ 4.5V, Qg = 10.5 nC, SO-8 with enhanced thermal pad | Higher on-resistance offsets lower Qg; thermal resistance 55°C/W vs. IRF7455PBF's 62°C/W | Better for thermally constrained layouts where gate drive is limited |
Compared with NTMFS4C06NT1G and SI7850DP-T1-GE3, IRF7455PBF offers the best balance of RDS(on), Qg, and thermal performance for 5–12V consumer power rails operating below 1 MHz, especially where gate drive voltage is limited to 4.5V.

FAQ
What is the maximum safe operating junction temperature for IRF7455PBF?
The absolute maximum junction temperature is +175°C, with derated continuous current above +100°C case temperature. Thermal design must ensure θJA ≤ 62°C/W on standard 2-layer FR4 with 1-in² copper pour to maintain TJ < 150°C at 8.9A.
Does IRF7455PBF require a gate resistor for typical 5V MCU drive?
A 10–22 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during fast switching. The 12 nC gate charge allows full turn-on within 200 ns using standard GPIO drivers without external boosting.
Can IRF7455PBF be used in avalanche energy-rated applications?
No - IRF7455PBF is not characterized or guaranteed for repetitive avalanche operation. Its datasheet specifies only unclamped inductive switching (UIS) rating of 32 mJ, intended for single-event fault tolerance, not sustained avalanche use.
Is the SO-8 thermal pad electrically isolated from the drain terminals?
Yes - the exposed drain pad is internally connected to pins 5–8 (drain) and must be soldered to a PCB copper area designated as drain potential. It is not isolated and must not be connected to source or ground planes.
