Product details
Overview
IRFHM8228TRPBF from Infineon Technologies is a 25 V, 25 A (TC = 25°C), N-channel PQFN-packaged Power MOSFET optimized as a synchronous rectifier in high-frequency buck converters. It delivers RDS(on) = 4.2 mΩ (typ) at VGS = 10 V and 6.7 mΩ (typ) at VGS = 4.5 V, with Qg = 9.0 nC (typ), low-profile 1.05 mm height, and MSL1 rating for consumer-grade reliability.
For engineers reviewing the IRFHM8228TRPBF datasheet, IRFHM8228TRPBF pinout, IRFHM8228TRPBF application, or IRFHM8228TRPBF equivalent, key selection criteria include its 3.7°C/W junction-to-PCB thermal resistance, industry-standard 8-pin PQFN layout, body diode recovery performance (trr = 14 ns typ), and compatibility with 400 kHz synchronous buck topologies requiring low conduction + switching loss trade-offs.
Technical Context
This device is a trench-based N-channel enhancement-mode MOSFET designed for high-efficiency DC-DC conversion where low RDS(on) and fast switching are critical. Its 8-pin PQFN package features five parallel drain terminals and dual source terminals to minimize package inductance and improve current sharing under high di/dt conditions.
The gate threshold voltage (VGS(th) = 1.35–2.35 V) enables robust 4.5 V logic-level drive, while its 195 pF Crss and 4.1 nC Qsw support clean turn-off in synchronous rectifier operation. The integrated body diode exhibits VSD = 1.0 V (max) at IS = 20 A and Qrr = 10–15 nC, minimizing reverse recovery losses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiR872DP-T1-GE3 | RDS(on) = 4.0 mΩ @ 10 V; Qg = 11.5 nC; same 3.3×3.3 mm PQFN but thicker (1.2 mm) | Higher gate charge increases driver loss; slightly worse thermal resistance (4.1°C/W) | Prefer when lowest RDS(on) is priority and board height allows 0.15 mm extra thickness. |
| DMTH2006LPS-13 | RDS(on) = 5.5 mΩ @ 10 V; Qg = 7.2 nC; 2.5×3.0 mm package with 3.5°C/W RθJC | Smaller footprint but lower current rating (20 A); faster switching due to lower Qg | Prefer when PCB area is constrained and peak current remains ≤20 A with margin. |
Compared with SiR872DP-T1-GE3 and DMTH2006LPS-13, IRFHM8228TRPBF offers the best balance of low RDS(on), low Qg, and ultra-low profile-making it optimal for thermally dense, height-sensitive synchronous buck designs where both conduction and switching losses must be minimized simultaneously.

FAQ
What is the maximum continuous drain current for IRFHM8228TRPBF at 100°C case temperature?
The maximum continuous drain current at TC = 100°C is 41 A when VGS = 10 V, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB thermal design per Infineon AN-1136, including ≥100 mm² of 2 oz copper connected to the exposed drain paddle.
Does IRFHM8228TRPBF support 3.3 V gate drive in practice?
No-its gate threshold voltage (VGS(th)) ranges from 1.35 V to 2.35 V, but RDS(on) rises sharply below 4.5 V. At VGS = 3.3 V, RDS(on) exceeds 15 mΩ (estimated from Fig 12), making it unsuitable for efficient operation. Minimum recommended gate drive is 4.5 V.
Can IRFHM8228TRPBF be used in avalanche mode?
Yes-it is rated for single-pulse avalanche energy (EAS) up to 50 mJ at TJ = 25°C. However, repetitive avalanche is not guaranteed. Layout must minimize stray inductance (per Fig 19), and pulse width must stay within the safe operating area defined in Fig 14 for reliable operation.
What is the recommended PCB footprint and stencil specification?
Infineon specifies a 3.3 mm × 3.3 mm land pattern with 0.35 mm solder mask opening and 0.15 mm stencil aperture for the exposed drain paddle, per Application Note AN-1136. Thermal vias (≥8 × 0.3 mm) under the paddle are required to achieve the 3.7°C/W RθJC rating.
