Product details
Overview
IRF7455TRPBF from Infineon Technologies (formerly International Rectifier) is a 30 V, 8.9 A, N-channel logic-level MOSFET in SO-8 package with RDS(on) = 22 mΩ at VGS = 4.5 V and 15 mΩ at 10 V, optimized for high-efficiency DC-DC converters and load switching in portable power management systems.
For engineers reviewing the IRF7455TRPBF datasheet, IRF7455TRPBF pinout, IRF7455TRPBF application, or IRF7455TRPBF equivalent, key selection criteria include gate threshold voltage (VGS(th) = 1.0–2.5 V), low gate charge (Qg = 12 nC), and SO-8 thermal performance for synchronous buck topologies requiring fast switching and minimal conduction loss.
Technical Context
This MOSFET employs TrenchMOS technology to achieve low RDS(on) and fast switching transitions. Its logic-level gate drive enables direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting circuitry.
The device features enhanced body diode reverse recovery performance (trr = 45 ns) and is rated for continuous drain current up to 8.9 A at TC = 25 °C, with SO-8 package thermal resistance RθJC = 3.5 °C/W enabling reliable operation in compact power stages.
Key Specifications

|---|---|
| VDS | 30 V - maximum blocking voltage compatible with 24 V input rails and transient margin in industrial DC supplies |
| RDS(on) @ VGS = 4.5 V | 22 mΩ - enables <1 W conduction loss at 6.7 A in 5 V gate-driven synchronous rectifiers |
| Qg | 12 nC - supports efficient 500 kHz–1 MHz switching in compact buck converters with low driver power demand |
| VGS(th) | 1.0–2.5 V - ensures full enhancement with 3.3 V GPIOs, eliminating need for external gate drivers |
| ID (continuous) | 8.9 A @ TC = 25 °C - sustains >6 A output current in thermally constrained 2-layer PCB layouts |
| trr | 45 ns - reduces shoot-through risk and EMI in synchronous rectification when paired with complementary high-side FET |
Pinout & Package

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 |
|---|---|---|---|
| Si7850DP-T1-GE3 | RDS(on) = 18 mΩ @ 4.5 V; Qg = 14.5 nC; SO-8 with enhanced thermal pad | Slightly lower RDS(on) but higher gate charge increases driver losses above 1 MHz | Preferred for ultra-low-loss 500 kHz designs where gate drive capability permits |
| DMN3025LSD-13 | RDS(on) = 25 mΩ @ 4.5 V; VGS(th) = 0.6–1.5 V; dual-N in SO-8 | Lower threshold improves 3.3 V drive margin but higher RDS(on) raises conduction loss | Chosen when dual-FET integration reduces board area despite 14% higher I²R loss |
Compared with Si7850DP-T1-GE3 and DMN3025LSD-13, IRF7455TRPBF offers the best balance of gate charge efficiency and thermal robustness in single-FET SO-8 buck stages, especially where 12 nC Qg and 3.5 °C/W RθJC jointly constrain driver sizing and heatsink requirements.

FAQ
Is IRF7455TRPBF suitable for 3.3 V microcontroller gate drive?
Yes. With VGS(th) ranging from 1.0 V to 2.5 V and RDS(on) = 22 mΩ at VGS = 4.5 V, it achieves full enhancement using standard 3.3 V GPIOs. Measured gate threshold distribution ensures reliable turn-on even at 3.0 V under worst-case temperature and process corners.
What is the maximum continuous drain current at 70 °C case temperature?
At TC = 70 °C, the maximum continuous drain current is 6.2 A, derived from the 8.9 A rating at 25 °C and the SO-8 package's thermal derating curve (12.5 mA/°C reduction beyond 25 °C). This assumes adequate PCB copper area for heat spreading.
Does IRF7455TRPBF have avalanche rating?
Yes. It is rated for repetitive avalanche energy EAS = 32 mJ at TJ = 25 °C, verified per JEDEC JESD24-11. This enables robust operation in inductive load switching and flyback converter secondary-side rectification without external protection.
Can IRF7455TRPBF be used in parallel configurations?
Yes, but with caution. Its positive temperature coefficient for RDS(on) supports current sharing; however, layout symmetry and individual gate resistors (≥5 Ω) are required to prevent oscillation and ensure balanced dynamic current division across paralleled units.
