Product details
Overview
IRFR5505GTRPBF from Infineon Technologies (formerly International Rectifier) is a p-channel enhancement-mode HEXFET Power MOSFET in D-Pak (TO-252) package, rated for −55 V VDS, 25 A ID (TC = 25°C), and 40 mΩ RDS(on) @ VGS = −10 V. It serves as a high-side load switch or reverse-polarity protection device in DC power distribution systems.
For engineers reviewing the IRFR5505GTRPBF datasheet, IRFR5505GTRPBF pinout, IRFR5505GTRPBF application, or IRFR5505GTRPBF equivalent, key selection criteria include verified p-channel conduction capability, D-Pak thermal performance under pulsed load conditions, gate threshold voltage consistency across temperature, and documented safe operating area (SOA) limits at 25°C and 100°C.
Technical Context
This MOSFET employs a planar silicon process with optimized cell pitch and trench-assisted body diode integration to achieve low RDS(on) while maintaining robust avalanche ruggedness (EAS = 390 mJ). Its p-channel architecture enables direct gate drive from microcontroller GPIOs without level-shifting when used in high-side configurations.
The device features a fully characterized body diode with trr = 120 ns and Qrr = 120 nC at IF = 25 A, supporting synchronous rectification in buck-derived topologies and enabling controlled reverse recovery in bidirectional current paths.
Key Specifications

| RDS(on) @ VGS = −10 V | 40 mΩ - Confirmed on-resistance enabling ≤1 W conduction loss at 5 A continuous drain current |
| ID (TC = 25°C) | 25 A - Continuous drain current rating with heatsink; derates to 17 A at TC = 100°C |
| VGS(th) | −2.0 to −4.0 V - Verified gate threshold range ensuring reliable turn-on with 3.3 V logic-level controllers |
| Qg | 52 nC - Total gate charge determining minimum driver current for 100 ns switching transitions |
| EAS | 390 mJ - Single-pulse avalanche energy rating validating robustness against inductive load transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar p-channel power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLR9343PbF | RDS(on) = 22 mΩ @ VGS = −4.5 V; lower VGS(th) (−1.0 to −2.5 V); TO-252 package same | Better suited for 3.3 V logic-driven high-side switches requiring lower gate drive voltage | Select when gate drive voltage is limited to ≤ −4.5 V and RDS(on) reduction outweighs higher cost |
| Si2305DS-T1-E3 | RDS(on) = 55 mΩ @ VGS = −4.5 V; SOT-23 package; lower ID (4.5 A) | Targeted for space-constrained low-current applications (< 5 A), not high-power load switching | Choose only for footprint-limited designs where current demand is ≤ 4.5 A and thermal budget permits SOT-23 |
Compared with IRFR5505GTRPBF, IRLL9343PbF offers superior low-voltage gate drive compatibility but lacks its 390 mJ avalanche rating, while Si2305DS-T1-E3 sacrifices current capacity and ruggedness for miniaturization-making IRFR5505GTRPBF optimal for thermally demanding 10–25 A industrial switching.

FAQ
What is the maximum junction temperature for continuous operation?
The IRFR5505GTRPBF has a maximum rated junction temperature of 175°C. Derating begins at TJ > 25°C per the datasheet's thermal resistance curve (RθJA = 62°C/W, RθJC = 3.0°C/W). For sustained 25 A operation, a minimum 25 cm² 2-oz copper pour with thermal vias is required to maintain TJ ≤ 135°C at ambient 70°C.
Does this MOSFET require a gate resistor for stability?
Yes-a 10–47 Ω gate series resistor is recommended to dampen parasitic oscillation during fast switching. The device's 52 nC gate charge and 1.2 nH source inductance interact with PCB layout to form an RLC network; omitting the resistor risks ringing above 100 MHz and unintended turn-on due to dV/dt coupling.
Can IRFR5505GTRPBF be used in linear (analog) regulation mode?
No-it is not characterized or qualified for linear-mode operation. The Safe Operating Area (SOA) graph shows no defined DC or pulse boundaries beyond 10 ms, and the body diode's reverse recovery behavior introduces instability under analog bias. Use only in saturated switching mode with defined dead time in half-bridge configurations.
Is the drain pad electrically isolated from the PCB ground plane?
No-the drain pad is internally connected to the MOSFET's drain terminal and must be routed as a high-current power net. When soldered to a PCB thermal pad, that pad must be electrically tied to the system's negative return path or load-side reference, not to signal ground, to avoid latch-up or ground loop currents.
