Product details
Overview
IRFR3707TRPBF from Infineon Technologies (formerly International Rectifier) is a 30V, 61A N-channel enhancement-mode power MOSFET in D-Pak (TO-252) package, featuring 13mΩ RDS(on) at VGS = 10V, ultra-low gate charge (19nC), and rated for high-frequency synchronous rectification in isolated DC-DC converters used in telecom and industrial power supplies.
For engineers reviewing the IRFR3707TRPBF datasheet, IRFR3707TRPBF pinout, IRFR3707TRPBF application, or IRFR3707TRPBF equivalent, key selection criteria include its 13mΩ on-resistance at 10V drive, 244A pulsed drain capability, 213mJ single-pulse avalanche energy rating, and optimized gate charge profile for hard-switched and resonant topologies.
Technical Context
This HEXFET device employs planar vertical DMOS structure with fully characterized avalanche performance and low reverse transfer capacitance (50pF), enabling robust operation under inductive switching stress. Its gate threshold voltage (1.0–3.0V) and transconductance (37S) support reliable turn-on with standard 3.3V/5V logic-level drivers when used with appropriate gate resistance.
The MOSFET integrates a fast body diode with 39–63ns reverse recovery time and 49–93nC Qrr, making it suitable for synchronous rectification where diode conduction and commutation losses must be minimized. Thermal resistance RθJC is 1.73°C/W, confirming efficient heat transfer to the PCB pad in surface-mount applications.

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 |
|---|---|---|---|
| IRLR3707ZPBF | Same RDS(on) (13mΩ) but logic-level gate (VGS(th) = 1.0–2.5V); 20nC Qg; identical D-Pak package | Better suited for 3.3V gate drive without level-shifting; slightly higher gate charge increases driver loss at >1MHz | Select when using microcontroller GPIO directly or when gate drive voltage is limited to ≤4.5V |
| STP30NF20 | Higher VDS (200V), higher RDS(on) (30mΩ), TO-220 package, 32nC Qg | Designed for offline flyback/forward primary switches; unsuitable for high-frequency sync rectification due to higher capacitance and thermal resistance | Choose only if 200V blocking and through-hole mounting are required; not drop-in for IRFR3707TRPBF layout |
Compared with IRLR3707ZPBF and STP30NF20, IRFR3707TRPBF offers optimal balance of low on-resistance, moderate gate charge, and D-Pak thermal performance for 30V synchronous rectifiers-making it preferred over logic-level variants when 10V gate drive is available and over high-voltage parts when board space and switching frequency are critical.

FAQ
Is IRFR3707TRPBF suitable for 3.3V gate drive?
No-its gate threshold voltage range is 1.0–3.0V, but full enhancement requires ≥4.5V for usable RDS(on). At 3.3V, RDS(on) exceeds 30mΩ, doubling conduction loss. For true 3.3V operation, use IRLR3707ZPBF instead, which guarantees 13mΩ at VGS = 4.5V.
What is the maximum recommended gate resistor value for 500kHz switching?
A 10Ω gate resistor is recommended for 500kHz operation with standard gate drivers. This balances switching speed (tr/tf ≈ 78ns/3.3ns) against ringing and EMI. Lower values (<5Ω) increase driver stress; higher values (>22Ω) extend td(off) beyond 11.8ns, raising switching loss disproportionately.
Can IRFR3707TRPBF replace IRFR3704 in an existing design?
Yes-both are D-Pak N-channel MOSFETs with identical pinout and footprint. IRFR3707TRPBF has lower RDS(on) (13mΩ vs. 20mΩ) and higher ID (61A vs. 49A), improving thermal margin. No layout change is needed, but gate drive strength should be verified due to higher Qg (19nC vs. 15nC).
Does this MOSFET require a heatsink when operating at 50A continuous?
No external heatsink is required if mounted on ≥1"² 2-oz copper pad with thermal vias. With RθJC = 1.73°C/W and PD ≈ 32.5W at 50A, junction temperature stays below 125°C ambient + (32.5 × 1.73) ≈ 181°C-within 175°C limit. However, derating to 45A is advised for 70°C ambient with no forced air.
