Overview
IRFR310TRLPBF 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 repetitive avalanche rating-designed for high-voltage DC-DC converters, offline switch-mode power supplies, and industrial motor control circuits.
For engineers reviewing the IRFR310TRLPBF datasheet, IRFR310TRLPBF pinout, IRFR310TRLPBF application, or IRFR310TRLPBF equivalent, this page delivers verified electrical parameters, thermal derating behavior, body diode recovery characteristics, and direct-mount PCB layout guidance per Vishay's recommended DPAK pad dimensions.
Technical Context
This third-generation trench MOSFET employs ruggedized silicon design with dynamic dV/dt rating up to 4.0 V/ns and full unclamped inductive switching (UIS) capability-enabling reliable operation under transient overvoltage and inductive load switching. Its 86 mJ single-pulse avalanche energy supports robustness in flyback and forward converter topologies.
The device integrates a low-leakage integral body diode (VSD = 1.6 V at 1.7 A, TJ = 25 °C) with 240–540 ns reverse recovery time and 0.85–1.6 μC Qrr, making it suitable for synchronous rectification and freewheeling applications where controlled diode conduction is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 400 V - Withstands peak line voltages up to 280 VAC RMS in offline SMPS designs without breakdown. |
| RDS(on) | 3.6 Ω @ VGS = 10 V - Enables <1.7 W conduction loss at 1.0 A continuous drain current in compact SMT layouts. |
| Qg | 12 nC - Supports fast switching with moderate gate drive strength (e.g., 1–2 A peak), reducing turn-on/turn-off times to <30 ns total. |
| ID (TC = 25 °C) | 1.7 A - Specifies maximum continuous current when case temperature is maintained at 25 °C via heatsinking or PCB copper area. |
| EAS | 86 mJ - Guarantees single-event avalanche survival under worst-case inductive switching conditions (e.g., transformer leakage energy). |
| TJ Range | −55 to +150 °C - Allows operation in extended industrial environments including motor drives and outdoor power supplies. |
| RthJA (PCB mount) | 50 °C/W - Defines thermal resistance from junction to ambient on 1"² FR-4 PCB, enabling ~2.5 W power dissipation at TA = 25 °C. |
Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain tab for thermal conduction and mechanical anchoring. Standard lead finish is Pb-free and halogen-free per Vishay specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts 10 V logic-level drive; threshold voltage 2.0–4.0 V enables compatibility with standard microcontroller GPIO or dedicated gate drivers. |
| D (Drain) | High-side power terminal | Connected to internal die backside; electrically tied to exposed metal tab-must be isolated from heatsink unless referenced to same potential. |
| S (Source) | Reference node / return path | Serves as local ground reference for gate drive; source inductance (LS = 7.5 nH) impacts switching waveform ringing and must be minimized in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Supports repeated inductive turn-off events up to IAR = 1.7 A and EAR = 2.5 mJ without degradation-critical for reliability in relay drivers and solenoid controls. |
| Dynamic dV/dt immunity | Rated 4.0 V/ns-prevents false turn-on during high-slew-rate transients in half-bridge or LLC resonant converter nodes. |
| Fast switching performance | td(on) = 7.9 ns, tr = 9.9 ns, td(off) = 21 ns, tf = 11 ns-enables >500 kHz operation with minimal overlap loss in hard-switched topologies. |
| Low gate charge asymmetry | Qgd/Qgs = 6.5/1.9 ≈ 3.4-provides predictable Miller plateau timing and simplifies gate driver selection for stable transition control. |
| Surface-mount optimized | DPAK footprint allows vapor-phase reflow compatibility and 1.5 W typical power dissipation on standard PCB copper-reducing need for external heatsinks. |
Applications

FAQ
What is the maximum continuous drain current for IRFR310TRLPBF at 100 °C case temperature?
The IRFR310TRLPBF supports 1.1 A continuous drain current at TC = 100 °C, derived from its linear derating factor of 0.20 W/°C and 25 W maximum power dissipation at TC = 25 °C. This value reflects thermal limitations-not device failure-and assumes adequate PCB copper area or heatsinking per Vishay's DPAK mounting guidelines.
Does IRFR310TRLPBF require a gate resistor for safe operation?
Yes, IRFR310TRLPBF benefits from an external gate resistor (typically 10–47 Ω) to control dI/dt and suppress oscillation caused by LS = 7.5 nH and LD = 4.5 nH parasitics. Without proper gate resistance, ringing during switching can exceed VGS = ±20 V absolute maximum and induce false turn-on due to Miller coupling.
Can IRFR310TRLPBF be used in place of IRFR3707TRLPBF?
No-IRFR310TRLPBF is not a direct replacement for IRFR3707TRLPBF due to higher RDS(on) (3.6 Ω vs. 2.2 Ω) and lower Qg (12 nC vs. 24 nC). Substituting IRFR310TRLPBF may increase conduction loss and thermal stress in high-current applications, though it improves switching speed in high-frequency designs.
What is the body diode forward voltage of IRFR310TRLPBF at 1.7 A and 25 °C?
The body diode forward voltage (VSD) of IRFR310TRLPBF is specified as 1.6 V maximum at IS = 1.7 A and TJ = 25 °C. This parameter directly affects freewheeling losses in buck or flyback topologies and must be considered alongside trr = 240–540 ns and Qrr = 0.85–1.6 μC for total diode conduction loss estimation.
Is IRFR310TRLPBF compatible with lead-free reflow soldering processes?
Yes, IRFR310TRLPBF is qualified for lead-free reflow soldering with peak temperature up to 260 °C for 10 seconds, per Vishay's package reliability data. Its DPAK (TO-252) construction supports vapor phase, infrared, and wave soldering-provided PCB pad design follows Vishay's recommended minimum dimensions (e.g., 0.224" × 0.180" thermal pad).
