Product details
Overview
IRFHM830TRPBF from Infineon Technologies is a 30 V, 77 A (TC(Bottom) = 25°C) N-channel Trench MOSFET in PQFN 3.3 × 3.3 mm package, featuring 3.8 mΩ RDS(on) @ 10 V, 15 nC typical Qg, and 2.5 Ω gate resistance-designed for high-efficiency DC motor inverters in battery-powered tools and e-bikes.
For engineers reviewing the IRFHM830TRPBF datasheet, IRFHM830TRPBF pinout, IRFHM830TRPBF application, or IRFHM830TRPBF equivalent, key selection criteria include low-conduction-loss switching at 4.5 V gate drive, thermal performance under PCB-limited cooling, and compatibility with standard SMT reflow profiles for high-volume motor control modules.
Technical Context
This MOSFET employs Infineon's HEXFET® Trench technology to achieve sub-4 mΩ on-resistance with fast switching (td(on) = 12 ns, tf = 9.2 ns) and low gate charge (Qg = 15 nC typ). Its dual-side thermal path design enables 3.4 °C/W junction-to-case (bottom) thermal resistance, supporting high-current operation without external heatsinking when mounted on 2 oz copper PCBs.
The device integrates a robust body diode with 37 A continuous source current rating, 1.0 V forward voltage at 20 A, and 17–26 ns reverse recovery time-enabling synchronous rectification and freewheeling in half-bridge motor drivers without external diodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB036N04LG | 40 V VDSS, 3.6 mΩ RDS(on), TO-263 package | Larger footprint, higher thermal mass; requires heatsink for same 77 A rating | Preferred where board space permits and higher voltage margin is needed |
| SiR872DP | 30 V VDSS, 3.7 mΩ RDS(on), 5×6 mm PowerPAK SO-8 | Higher RθJA (46 °C/W), lower current density due to larger footprint | Selected when existing layout uses SO-8 footprints and thermal budget allows |
Compared with IPB036N04LG and SiR872DP, IRFHM830TRPBF offers superior power density (3.3 × 3.3 mm) and lowest thermal resistance to PCB (3.4 °C/W), making it optimal for space-constrained, high-current motor inverters where thermal management relies primarily on PCB copper.

FAQ
What is the maximum continuous drain current for IRFHM830TRPBF at 100°C case temperature?
The maximum continuous drain current is 49 A when the bottom case temperature is maintained at 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PQFN package and PCB thermal interface; operation above this current requires active cooling or reduced ambient temperature.
Does IRFHM830TRPBF require a gate resistor for safe operation?
While the device includes an internal 2.5 Ω gate resistance, an external series gate resistor (typically 5–10 Ω) is recommended to dampen ringing, control dV/dt, and limit peak gate current during fast switching. This improves EMI performance and prevents shoot-through in half-bridge configurations.
Can IRFHM830TRPBF be used with 3.3 V microcontroller GPIOs?
Yes-the gate threshold voltage ranges from 1.35 V to 2.35 V, ensuring reliable turn-on with 3.3 V logic. However, full enhancement (to achieve 3.8 mΩ RDS(on)) requires ≥4.5 V gate drive; for optimal conduction loss, use a dedicated gate driver or level shifter.
Is the exposed thermal pad electrically isolated from the drain terminals?
No-the exposed thermal pad is internally connected to the drain terminals (pins 1–7) and must be soldered to a PCB copper pour tied to the system drain net. This dual connection provides both thermal conduction and low-inductance current return, critical for high-frequency motor drive stability.
