Product details
Overview
IRFR3504ZTRPBF from Infineon Technologies (formerly International Rectifier) is a 40V, 42A N-channel D-Pak power MOSFET with 9.0mΩ RDS(on) at VGS = 10V, 175°C junction rating, and rated repetitive avalanche capability. It serves as a high-efficiency main or synchronous rectifier switch in DC-DC converters, motor drives, and power supplies.
For engineers reviewing the IRFR3504ZTRPBF datasheet, IRFR3504ZTRPBF pinout, IRFR3504ZTRPBF application, or IRFR3504ZTRPBF equivalent, key selection criteria include its low conduction loss, fast switching (tr = 74ns, tf = 38ns), body diode recovery (trr = 18–27ns), thermal robustness (RθJC = 1.66°C/W), and D-Pak package compatibility with high-current PCB layouts.
Technical Context
This HEXFET® device uses advanced silicon processing to minimize on-resistance per die area while maintaining rugged unclamped inductive switching performance. Its gate charge profile (Qg = 30–45nC, Qgd = 12nC) supports efficient hard-switching in buck and half-bridge topologies up to several hundred kHz.
The integrated body diode exhibits low forward voltage (VSD ≤ 1.3V at 42A) and controlled reverse recovery (Qrr = 9.2–14nC), enabling reliable operation in synchronous rectification without external Schottky supplementation in many 12V–24V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage for 12V/24V bus applications with margin against transients |
| RDS(on) | 9.0mΩ max @ VGS = 10V - Enables ≤1.6W conduction loss at 42A continuous drain current |
| ID | 42A @ TC = 25°C - Sustains high pulsed load currents in motor gate drivers and SMPS primary switches |
| tr/tf | 74ns/38ns - Supports fast switching with reduced overlap loss in high-frequency converters |
| EAS | 310mJ (tested) - Withstands single-pulse inductive energy without failure under defined test conditions |
| RθJC | 1.66°C/W - Allows direct heatsinking to chassis or copper pour for thermal management |
| VGS(th) | 2.0–4.0V - Compatible with standard 3.3V/5V logic-level gate drivers when used with sufficient drive strength |
Pinout & Package
IRFR3504ZTRPBF is housed in a surface-mount D-Pak (TO-252AA) package with three terminals: Drain (tab), Source (pin 1), and Gate (pin 2). The exposed drain pad provides low-inductance, high-current path and thermal interface to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current-carrying terminal, electrically connected to package backside | Provides low-inductance, high-current path and primary thermal conduction path to PCB heatsink area |
| Source (Pin 1) | Reference node for gate drive and current return path | Connects directly to power ground plane; critical for minimizing source inductance (LS = 7.5nH) |
| Gate (Pin 2) | Control input for channel conduction | Requires <15Ω series resistance to damp ringing; total gate charge Qg = 30–45nC defines driver sizing |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 9.0mΩ enables <1.6W conduction loss at full 42A, reducing thermal stress in compact power stages |
| 175°C maximum junction temperature | Supports operation in sealed enclosures or high-ambient environments without derating below 100°C case temp |
| Repetitive avalanche rated | Validated for repeated unclamped inductive switching up to Tjmax, eliminating need for external snubbers in many motor control designs |
| Fast body diode recovery | trr = 18–27ns and Qrr = 9.2–14nC reduce switching loss and EMI in synchronous rectifier configurations |
| Lead-free and RoHS-compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1), suitable for standard reflow assembly without baking |

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 |
|---|---|---|---|
| STP40NF10 | 100V VDSS, 40A ID, 28mΩ RDS(on), TO-220 package | Higher voltage rating but higher on-resistance and larger footprint; unsuitable for space-constrained D-Pak layouts | Select only if 100V blocking is required and thermal budget allows higher conduction loss |
| IRL3803PbF | 30V VDSS, 68A ID, 8.0mΩ RDS(on), D-Pak, logic-level (VGS(th) = 1.0–2.0V) | Lower voltage rating limits use to ≤15V systems; lower threshold enables direct 3.3V MCU drive without level shift | Prefer for 3.3V-control applications where 30V blocking suffices and gate drive simplicity is prioritized |
Compared with STP40NF10 and IRL3803PbF, IRFR3504ZTRPBF offers optimal balance of 40V rating, ultra-low on-resistance, D-Pak form factor, and proven avalanche ruggedness-making it preferred for 12V–24V industrial and automotive power stages requiring both efficiency and reliability.

FAQ
Is IRFR3504ZTRPBF suitable for logic-level gate drive?
No-it is not a logic-level MOSFET. Its gate threshold voltage ranges from 2.0V to 4.0V, and it requires ≥10V VGS to achieve rated RDS(on). Driving it from 3.3V or 5V microcontrollers without a gate driver will result in excessive conduction loss and thermal instability.
What is the maximum continuous drain current at 100°C case temperature?
At TC = 100°C, the continuous drain current is 25A (derated from 42A at 25°C), as specified in the Absolute Maximum Ratings table. This reflects thermal limitation of the D-Pak package, not silicon current capability.
Does IRFR3504ZTRPBF have an integrated ESD protection diode on the gate?
No-this device lacks built-in gate ESD protection. External Zener clamping (e.g., 12V TVS between gate and source) is recommended in systems exposed to handling or board-level ESD events to prevent gate oxide damage.
Can IRFR3504ZTRPBF be paralleled with identical units for higher current capacity?
Yes-its positive temperature coefficient of RDS(on) (see Fig. 10) ensures inherent current sharing. However, matched gate drive layout (equal trace length/impedance) and thermal coupling (shared heatsink) are essential to avoid imbalance and localized overheating.
