Product details
Overview
IRFR310TRRPBF from Vishay Siliconix is a 400 V, 1.7 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 3.6 Ω RDS(on) at VGS = 10 V, 12 nC total gate charge, and full repetitive avalanche rating - used in offline switch-mode power supplies, DC-DC converters, and motor control circuits requiring rugged high-voltage switching.
For engineers reviewing the IRFR310TRRPBF datasheet, IRFR310TRRPBF pinout, IRFR310TRRPBF application, or IRFR310TRRPBF equivalent, this page delivers verified electrical parameters, thermal derating behavior, body diode recovery characteristics, PCB-mount power dissipation limits, and validated alternative parts for high-reliability industrial and power-conversion designs.
Technical Context
The IRFR310TRRPBF employs third-generation planar vertical DMOS technology optimized for fast switching and robust unclamped inductive switching (UIS) performance. It supports 86 mJ single-pulse avalanche energy and 2.5 mJ repetitive avalanche energy under defined test conditions (VDD = 50 V, IAS = 1.7 A).
Its dynamic characteristics include 170 pF input capacitance (Ciss), 6.3 pF reverse transfer capacitance (Crss), and 240–540 ns body diode reverse recovery time (trr) - enabling efficient hard-switched topologies with controlled dV/dt (4.0 V/ns peak diode recovery rating).
Key Specifications

|---|---|
| VDS | 400 V - supports primary-side switching in 230 VAC offline SMPS without derating |
| RDS(on) | 3.6 Ω @ VGS = 10 V - determines conduction loss in continuous-current operation |
| ID (continuous) | 1.7 A @ TC = 25 °C - usable current limit with adequate heatsinking on PCB |
| Qg | 12 nC - defines gate drive power requirement and switching speed trade-off |
| EAS | 86 mJ - enables reliable operation under transient overloads and inductive kickback |
| trr | 240–540 ns - impacts turn-on loss and EMI in synchronous rectification or freewheeling paths |
| RthJA (PCB mount) | 50 °C/W - sets thermal rise for 2.5 W max power dissipation on 1" FR-4 board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR320TRPBF | Higher VDS = 500 V, higher RDS(on) = 5.5 Ω, same DPAK package | Better suited for 380 VDC bus systems; increased conduction loss at 1.7 A | Select when system requires higher voltage margin and can tolerate +53% RDS(on) |
| SiHFR310-GE3 | Identical electrical specs and DPAK footprint; halogen-free, RoHS-compliant variant | No functional difference; preferred for EU/automotive compliance-driven designs | Drop-in replacement where lead-free/halogen-free certification is mandatory |
Compared with IRFR310TRRPBF, IRFR320TRPBF offers extended voltage headroom but sacrifices conduction efficiency, while SiHFR310-GE3 provides identical performance with enhanced environmental compliance - making the latter ideal for new designs targeting global regulatory alignment without layout changes.

FAQ
What is the maximum continuous drain current for IRFR310TRRPBF at 100 °C case temperature?
The IRFR310TRRPBF supports 1.1 A continuous drain current at TC = 100 °C, per its linear derating factor of 0.20 W/°C from the 25 °C rating of 25 W. This reflects thermal limitation rather than device failure - sustained operation above this current requires active cooling or reduced ambient temperature to maintain junction temperature ≤150 °C. The IRFR310TRRPBF datasheet confirms this value in the Absolute Maximum Ratings table.
Does IRFR310TRRPBF have a built-in body diode, and what are its key parameters?
Yes, the IRFR310TRRPBF integrates a monolithic body diode with 1.7 A continuous forward current rating (IS), 6.0 A pulsed capability (ISM), and 1.6 V forward voltage (VSD) at 1.7 A and 25 °C. Its reverse recovery time (trr) ranges from 240 to 540 ns, and reverse recovery charge (Qrr) is 0.85–1.6 μC - critical for evaluating commutation loss in synchronous rectification or freewheeling paths. These values are specified in the Drain-Source Body Diode Characteristics section of the IRFR310TRRPBF datasheet.
Can IRFR310TRRPBF be driven directly by a 3.3 V microcontroller GPIO?
No - the IRFR310TRRPBF has a gate threshold voltage (VGS(th)) range of 2.0–4.0 V and requires ≥10 V gate drive for full enhancement and low RDS(on). At 3.3 V, it remains partially on with significantly elevated RDS(on), leading to excessive conduction loss and thermal runaway. A dedicated gate driver (e.g., TC4427) or level-shifting circuit is required to deliver 10–15 V to the IRFR310TRRPBF gate. This behavior is confirmed by the Transfer Characteristics curve in the IRFR310TRRPBF datasheet.
What is the thermal resistance from junction to ambient for IRFR310TRRPBF when mounted on a standard PCB?
When mounted on a 1" square FR-4 PCB, the IRFR310TRRPBF exhibits a maximum junction-to-ambient thermal resistance (RthJA) of 50 °C/W, enabling 2.5 W maximum power dissipation at TA = 25 °C. This value assumes no additional copper pour or heatsinking - adding thermal vias or a 2 oz copper plane can reduce RthJA by up to 30%. The IRFR310TRRPBF datasheet specifies this in the Thermal Resistance Ratings table under "PCB mounted, steady-state".
Is IRFR310TRRPBF suitable for use in automotive applications?
The IRFR310TRRPBF is not AEC-Q101 qualified and lacks automotive-grade screening, temperature cycling, or humidity testing per industry standards. While its -55 to +150 °C operating range meets under-hood temperature extremes, Vishay does not certify it for automotive safety-critical functions. For such use, designers should select AEC-Q101-qualified equivalents like SiHFU310-GE3 or consult Vishay's automotive-grade portfolio. This distinction is explicitly noted in Vishay's product categorization documentation for the IRFR310TRRPBF family.
