Product details
Overview
IRFU9310 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in straight-lead (through-hole) IPAK (TO-251) 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 is fully avalanche-rated and optimized for high-voltage DC-DC converters, offline switch-mode power supplies, and industrial motor control circuits requiring rugged, through-hole mounted switching.
For engineers reviewing the IRFU9310 datasheet, IRFU9310 pinout, IRFU9310 application, or IRFU9310 equivalent, key selection criteria include its -400 V blocking capability, low gate charge (13 nC), fast switching performance (td(on) = 11 ns), and suitability for unclamped inductive load handling with 92 mJ single-pulse avalanche energy.
Technical Context
This third-generation Vishay power MOSFET uses advanced silicon processing to achieve low on-resistance per die area while maintaining high voltage ruggedness. Its P-channel architecture enables high-side switching without level-shifting circuitry in buck or flyback topologies.
The device features a fully rated avalanche capability (EAS = 92 mJ), fast body diode recovery (trr = 170–260 ns), and low reverse transfer capacitance (Crss = 8.0 pF), supporting stable high-frequency operation under hard-switching conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -400 V - Supports primary-side switching in 380 V DC bus and 230 V AC input offline SMPS designs. |
| RDS(on) | 7.0 Ω @ VGS = -10 V - Enables low conduction loss in low-current, high-voltage applications (e.g., <2 A loads). |
| Qg | 13 nC - Reduces gate drive power requirement and supports efficient 100–500 kHz switching in isolated DC-DC converters. |
| ID (cont.) | -1.8 A @ TC = 25 °C - Specifies maximum steady-state current with adequate heatsinking; derates linearly above 25 °C. |
| EAS | 92 mJ - Ensures reliable operation during unclamped inductive turn-off events (e.g., relay driving, solenoid control). |
| tr/tf | 10 ns / 24 ns - Enables fast transition between on/off states, minimizing switching losses in high-frequency topologies. |
| VGS(th) | -2.0 to -4.0 V - Confirms logic-level compatible gate drive when using -5 V or -10 V bias; avoids spurious turn-on near 0 V. |
Pinout & Package
IRFU9310 is housed in an IPAK (TO-251) straight-lead through-hole package with three terminals: Drain (D), Gate (G), and Source (S). The package features a thermally enhanced leadframe with exposed drain pad for PCB heat sinking and complies with JEDEC TO-251AA outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main high-voltage current path output | Connected to high-side rail or inductive load return; electrically tied to metal tab for thermal conduction to PCB copper. |
| Gate (G) | Control terminal for channel modulation | High-impedance input requiring ≤ ±20 V drive; low Qgs (3.2 nC) enables fast, low-power switching transitions. |
| Source (S) | Reference node for gate drive and current return | Serves as common reference for VGS; must be routed with minimal inductance to avoid oscillation during fast dI/dt events. |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche-rated | 92 mJ single-pulse EAS ensures robustness against inductive kickback without external snubbers in relay/solenoid drivers. |
| Low Qgd/Qg ratio | 5.0/13 = 38.5 % - Improves switching stability and reduces Miller-induced shoot-through risk in high-dV/dt environments. |
| P-channel topology | Eliminates need for floating gate drivers in high-side configurations, simplifying layout in buck regulators and OR-ing circuits. |
| Fast body diode | trr = 170–260 ns and Qrr = 640–960 nC - Minimizes reverse recovery loss and EMI in freewheeling paths of flyback and forward converters. |
| Through-hole IPAK package | Enables mechanical reliability and thermal anchoring in industrial equipment where vibration resistance and long-term solder joint integrity are critical. |

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 |
|---|---|---|---|
| IRFR9310 | Same silicon die but in surface-mount DPAK (TO-252) package; identical VDS, RDS(on), Qg, and avalanche specs. | Requires reflow-compatible PCB layout; unsuitable for through-hole assembly or high-vibration environments. | Select IRFR9310 only when automated SMT production and space-constrained layouts are prioritized over mechanical robustness. |
| SiHFU9310 | Lead (Pb)-free and halogen-free variant of IRFU9310; identical electrical and thermal specifications; same IPAK package and pinout. | No functional difference; required only for RoHS-compliant or green-design programs. | Choose SiHFU9310 when environmental compliance (IEC 61249-2-21, J-STD-609) is mandatory for end-product certification. |
Compared with IRFU9310, IRFR9310 offers identical performance in a surface-mount format-ideal for high-density boards-but sacrifices mechanical retention strength; SiHFU9310 delivers identical through-hole functionality with full RoHS compliance, making it the drop-in replacement for regulated markets without design change.

FAQ
What is the maximum junction temperature rating for the IRFU9310?
The IRFU9310 has an operating junction and storage temperature range of -55 °C to +150 °C. Its absolute maximum junction temperature is +150 °C, beyond which safe operation is not guaranteed. Thermal design must ensure that under worst-case power dissipation (50 W at TC = 25 °C), the actual TJ remains within this limit using appropriate heatsinking and PCB copper area.
Can the IRFU9310 be used with a +5 V logic-level gate drive?
No-the IRFU9310 is not a logic-level MOSFET. Its gate threshold voltage (VGS(th)) ranges from -2.0 V to -4.0 V, and its RDS(on) is specified at VGS = -10 V. A +5 V drive cannot turn it on; instead, a negative gate drive referenced to source (e.g., -10 V) is required. For +5 V compatibility, consider Vishay's SiHFR024 or similar logic-level P-channel devices.
What is the avalanche energy rating of the IRFU9310, and how is it tested?
The IRFU9310 is rated for 92 mJ single-pulse avalanche energy (EAS) under test conditions of L = 57 mH, Rg = 25 Ω, and IAS = -1.8 A, starting from TJ = 25 °C. This rating is verified per JEDEC standard JESD24-1 and reflects the device's ability to absorb inductive energy without failure during unclamped inductive switching events.
How does the IRFU9310's body diode performance compare to standard rectifiers?
The IRFU9310's intrinsic body diode has a forward voltage (VSD) of ≤ -4.0 V at IS = -1.1 A and TJ = 25 °C, with reverse recovery time (trr) of 170–260 ns and Qrr of 640–960 nC. While slower and higher-loss than dedicated ultrafast rectifiers, it provides sufficient performance for low-frequency freewheeling in flyback and forward converters where synchronous rectification is not implemented.
Is the IRFU9310 pin-compatible with other TO-251 devices like the IRFU1N60A?
No-IRFU9310 and IRFU1N60A share the same IPAK (TO-251) package outline and 3-pin straight-lead configuration, but they differ in pin assignment: IRFU9310 uses G-D-S (left-to-right, lead side view), whereas IRFU1N60A uses G-S-D. Swapping them without verifying pinout will cause catastrophic failure. Always confirm terminal orientation using the Vishay package drawing 91362 before PCB layout.
