Product details
Overview
IRFR3504PBF from Infineon Technologies (formerly International Rectifier) is a 40V, 87A N-channel enhancement-mode power MOSFET in D-Pak surface-mount package, featuring 9.2mΩ RDS(on) at VGS = 10V, 175°C maximum junction temperature, and 240mJ single-pulse avalanche energy - deployed in DC-DC synchronous buck converters, motor drive half-bridges, and industrial power supplies.
For engineers reviewing the IRFR3504PBF datasheet, IRFR3504PBF pinout, IRFR3504PBF application, or IRFR3504PBF equivalent, key selection criteria include its low conduction loss at high current, fast switching (tr = 53ns, tf = 22ns), body diode recovery performance (trr = 53–80ns), and thermal robustness under repetitive avalanche stress.
Technical Context
This HEXFET® device uses advanced silicon processing to minimize on-resistance per die area while maintaining rated 40V VDS breakdown and ±20V gate voltage tolerance. Its 7.8–9.2mΩ RDS(on) enables high-efficiency operation at 30A continuous drain current with PCB-mount thermal resistance of 50°C/W.
The MOSFET supports fast switching via low gate charge (Qg = 48–71nC, Qgd = 13–20nC) and exhibits controlled body diode behavior (VSD = 1.3V at 30A, trr = 53ns typical), making it suitable for hard-switched topologies where reverse recovery impacts EMI and losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40V - Maximum blocking voltage before avalanche onset; defines use in ≤36V nominal bus systems. |
| RDS(on) | 7.8–9.2mΩ @ VGS = 10V, ID = 30A - Directly determines I²R conduction loss in high-current paths. |
| ID (TC = 25°C) | 87A - Silicon-limited continuous drain current; usable up to 61A at 100°C case temperature. |
| EAS | 240mJ (tested 480mJ) - Quantifies unclamped inductive switching robustness without external snubbing. |
| tr/tf | 53ns/22ns @ VDD = 20V, ID = 30A - Enables >500kHz switching in optimized gate-drive layouts. |
| Qg | 48–71nC - Gate charge magnitude governing driver power and switching transition time. |
| TJ max | +175°C - Allows sustained operation in thermally constrained enclosures without derating below ambient. |
Pinout & Package
D-Pak (TO-252AA) surface-mount package with gull-wing leads; designed for vapor-phase, infrared, or wave soldering. Thermal pad on drain connects directly to PCB copper for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab/Drain) | Drain terminal (internally connected to exposed metal tab) | Primary current path and thermal interface; must be soldered to large copper pour for RθJC = 1.09°C/W. |
| Pin 2 (Source) | Source terminal | Reference node for gate drive and current sensing; low-inductance layout critical for switching stability. |
| Pin 3 (Gate) | Gate terminal | High-impedance control input; requires <10Ω series resistance to damp ringing during fast transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 7.8mΩ typ. at 10V gate drive - reduces conduction loss by ≥35% vs. legacy 40V MOSFETs in 30A applications. |
| 175°C operating temperature | Rated junction limit - enables full current delivery in sealed industrial enclosures without forced air. |
| Fast switching speed | tr = 53ns, tf = 22ns - minimizes overlap loss in synchronous rectification and PWM control. |
| Repetitive avalanche rating | Allowed up to Tjmax - supports reliable operation in inductive load switching without external clamping. |
| Low gate-to-drain charge (Qgd) | 13–20nC - suppresses Miller-induced shoot-through in half-bridge configurations. |
Applications
| DC-DC Synchronous Buck Converter | Brushless DC Motor Half-Bridge |

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 |
|---|---|---|---|
| STP40NF10L | RDS(on) = 12.5mΩ @ 10V, VDS = 100V, TO-220 package | Higher voltage rating but higher on-resistance and through-hole mounting | Select when 100V blocking is required and board space permits larger package. |
| AOB414 | RDS(on) = 8.0mΩ @ 10V, VDS = 40V, DFN5x6 package, no exposed drain tab | Lower thermal resistance (RθJA = 35°C/W) but requires careful PCB thermal via design | Select for ultra-thin designs where D-Pak height is prohibitive and thermal vias are feasible. |
Compared with STP40NF10L and AOB414, IRFR3504PBF offers superior thermal coupling via its solderable drain tab and proven avalanche ruggedness - critical for motor drives and uninterruptible power systems where transient overloads occur.

FAQ
What is the maximum continuous drain current for IRFR3504PBF at 100°C case temperature?
The maximum continuous drain current is 61A at TC = 100°C, as specified in the Absolute Maximum Ratings table. This value reflects thermal limitation of the D-Pak package rather than silicon capability, which remains rated for 87A at 25°C case temperature.
Does IRFR3504PBF have a qualified lead-free finish and RoHS compliance?
Yes, IRFR3504PBF carries the "PbF" suffix indicating lead-free termination and full compliance with EU RoHS Directive 2011/65/EU. The device uses matte tin plating over copper leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life.
Can IRFR3504PBF be used in linear (analog) mode operation?
No - IRFR3504PBF is not characterized or guaranteed for linear mode operation. Its Safe Operating Area (SOA) curve shows pulse-limited operation only; sustained linear bias risks thermal runaway due to positive temperature coefficient of RDS(on) and lack of SOA derating data beyond 10ms pulses.
What is the recommended gate resistor value for driving IRFR3504PBF in a 300kHz buck converter?
A 4.7Ω to 6.8Ω non-inductive gate resistor is recommended to balance switching speed and gate-drive ringing. At 300kHz, this yields ~15–20ns effective rise/fall control while limiting peak gate current to <2A and suppressing oscillation induced by LS = 7.5nH and LD = 4.5nH internal inductances.
