Product details
Overview
IRFR9310TR from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -400 V drain-source voltage, 7.0 Ω RDS(on) at VGS = -10 V, and -1.8 A continuous drain current at TC = 25 °C. It delivers fully avalanche-rated ruggedness and fast switching for high-voltage DC-DC converters, industrial motor controls, and solid-state relay replacements.
For engineers reviewing the IRFR9310TR datasheet, IRFR9310TR pinout, IRFR9310TR application, or IRFR9310TR equivalent, key selection criteria include its -400 V blocking capability, low gate charge (13 nC), body diode recovery time (170–260 ns), thermal resistance (RthJC = 2.5 °C/W), and DPAK footprint compatibility with automated SMT assembly.
Technical Context
This third-generation Vishay power MOSFET uses advanced silicon processing to achieve low on-resistance per die area while maintaining robust avalanche energy rating (EAS = 92 mJ). Its P-channel topology enables high-side switching without level-shifting circuitry in buck regulators and offline power supplies.
The device integrates a fast-recovery body diode (trr = 170–260 ns, Qrr = 640–960 nC) and exhibits stable gate threshold voltage (-2.0 to -4.0 V) across temperature. Dynamic parameters-including Ciss = 270 pF, Coss = 50 pF, and Crss = 8.0 pF-are specified at VDS = -25 V, enabling accurate snubber and gate drive design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -400 V - Supports primary-side switching in 380 V DC bus and 277 V AC line-powered systems |
| RDS(on) | 7.0 Ω @ VGS = -10 V - Enables <1.1 A continuous conduction with ≤7.7 W conduction loss at TC = 25 °C |
| Qg | 13 nC - Determines gate driver current requirement (~13 mA avg. for 1 MHz switching with 1 kΩ gate resistor) |
| EAS | 92 mJ - Allows unclamped inductive switching without failure under IAS = -1.8 A, L = 57 mH conditions |
| tr/tf | 10 ns / 24 ns - Supports >500 kHz hard-switching in flyback and forward topologies with minimal switching loss |
| RthJC | 2.5 °C/W - Enables 50 W power dissipation with ≤125 °C junction rise above 25 °C case temperature |
| VGS(th) | -2.0 to -4.0 V - Ensures reliable turn-on with standard -10 V gate drive while rejecting noise up to ±20 V |

Applications
| Industrial Motor Control | AC-DC Power Supply |
|---|---|
|
Use Scenario: High-side switching in 3-phase inverter half-bridge legs for 24–48 V BLDC motor drives. IC Role / Device Role / Timing Role: P-channel MOSFET providing controlled current path from bus to phase winding during upper-arm conduction. Use Value: -400 V rating accommodates 2× bus voltage spikes; 7.0 Ω RDS(on) limits I²R loss to <2.3 W at 1.8 A peak. |

IC Role / Device Role / Timing Role: High-voltage P-channel switch controlling energy transfer timing and clamping waveform shape. Use Value: 92 mJ EAS withstands transformer leakage inductance energy without snubber; 13 nC Qg enables clean 200 kHz switching. |

IC Role / Device Role / Timing Role: Voltage-controlled solid-state switch replacing mechanical contacts with microsecond response and zero bounce. Use Value: Fully avalanche-rated operation ensures reliability under inductive load turn-off; -400 V VDS provides 2× safety margin over 240 V system max. |

IC Role / Device Role / Timing Role: P-channel MOSFET operating as secondary-side synchronous rectifier or primary-side high-side switch. Use Value: Fast 10 ns rise time minimizes dead-time loss; body diode trr < 260 ns prevents reverse recovery shoot-through in synchronous operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiHFR9310TR-GE3 | Same silicon die, identical VDS, RDS(on), Qg, and avalanche rating; Pb-free/halogen-free packaging per JEDEC J-STD-609A Class 2a | No functional difference; qualified for RoHS-compliant and green-chemistry manufacturing lines | Select when lead-free compliance and halogen-free material declaration are required by OEM procurement policy |
| IRFU9310PbF | Identical electrical specs but IPAK (TO-251) through-hole package; RthJC = 2.5 °C/W same, but RthJA higher due to leadframe thermal path | Requires wave soldering and manual assembly; unsuitable for high-density SMT production | Choose only for legacy through-hole designs or prototyping where DPAK reflow is unavailable |
Compared with IRFR9310TR, SiHFR9310TR-GE3 offers identical performance with enhanced environmental compliance, while IRFU9310PbF trades SMT scalability for through-hole serviceability-neither is pin-compatible due to differing package footprints and mounting methods.

FAQ
What is the maximum continuous drain current for IRFR9310TR at 100 °C case temperature?
The IRFR9310TR supports -1.1 A continuous drain current at TC = 100 °C, derated linearly from -1.8 A at 25 °C using a 0.40 W/°C factor. This value is confirmed in the Absolute Maximum Ratings table of Vishay document 91284, and reflects thermal limitation-not silicon current capability-under sustained PCB-mounted operation.
Does IRFR9310TR have a built-in body diode, and what are its key parameters?
Yes, the IRFR9310TR integrates a parasitic body diode inherent to its vertical P-channel MOSFET structure. Key parameters include -1.9 A continuous source-drain current (IS), -7.6 A pulsed rating (ISM), -4.0 V forward voltage (VSD) at -1.1 A and 25 °C, and 170–260 ns reverse recovery time (trr) with 640–960 nC recovered charge (Qrr), all specified in the Drain-Source Body Diode Characteristics section.
Can IRFR9310TR be used with logic-level gate drive (e.g., 3.3 V or 5 V)?
No-IRFR9310TR is not a logic-level MOSFET. Its gate threshold voltage range is -2.0 V to -4.0 V, and RDS(on) is specified only at VGS = -10 V. At VGS = -5 V, RDS(on) increases significantly (not characterized in datasheet), resulting in excessive conduction loss. A dedicated gate driver delivering -10 V to -15 V is required for full enhancement.
What is the thermal resistance from junction to case (RthJC) for IRFR9310TR, and how is it measured?
The IRFR9310TR has a maximum junction-to-case (drain) thermal resistance of 2.5 °C/W, measured between the silicon die and the exposed drain pad on the DPAK package bottom. This value assumes proper soldering to a minimum 1" square copper area on FR-4 PCB, as defined in the Thermal Resistance Ratings table of Vishay document 91284.
Is IRFR9310TR suitable for avalanche energy handling in unclamped inductive switching?
Yes-the IRFR9310TR is fully avalanche rated with 92 mJ single-pulse avalanche energy (EAS) and 5.0 mJ repetitive avalanche energy (EAR). These values are validated per test condition: L = 57 mH, IAS = -1.8 A, Rg = 25 Ω, starting TJ = 25 °C. Operation within these limits avoids permanent degradation during transient overloads.
