Product details
Overview
IRFU9214 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in straight-lead IPAK (TO-251) package, rated for -250 V drain-source voltage, 3.0 Ω RDS(on) at VGS = -10 V, and -2.7 A continuous drain current at TC = 25 °C. It delivers fully avalanche-rated ruggedness and fast switching for high-voltage DC-DC converters and industrial motor control.
For engineers reviewing the IRFU9214 datasheet, IRFU9214 pinout, IRFU9214 application, or IRFU9214 equivalent, this device is selected for high-side switching in 200–250 V systems requiring reliable unclamped inductive turn-off, low gate charge (14 nC), and through-hole mounting compatibility with thermal relief via case-connected drain.
Technical Context
This third-generation Vishay power MOSFET uses advanced silicon processing to achieve low on-resistance per die area while maintaining robust avalanche capability (EAS = 100 mJ). Its P-channel topology enables high-side configuration without level-shifting circuitry in buck or half-bridge topologies.
The device features a built-in body diode with 150–220 ns reverse recovery time and 870–1300 nC Qrr, optimized for synchronous rectification and flyback snubberless operation. Gate drive requirements are defined by VGS(th) of -2.0 to -4.0 V and total gate charge of 14 nC at -10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -250 V - Supports 200 V DC bus designs with 25 % safety margin against transients |
| RDS(on) | 3.0 Ω @ VGS = -10 V - Enables ≤ 21.9 W conduction loss at -2.7 A (TC = 25 °C) |
| Qg | 14 nC - Determines gate driver current requirement (~1.4 mA avg. for 100 kHz, 10 V swing) |
| ID (cont.) | -2.7 A @ TC = 25 °C - Sets heatsink sizing baseline for forced-air or PCB copper thermal management |
| EAS | 100 mJ - Allows safe single-pulse energy absorption during inductive load switching without external snubber |
| RthJC | 2.5 °C/W - Defines maximum junction-to-case temperature rise per watt dissipated; critical for thermal interface design |
| VGS(th) | -2.0 to -4.0 V - Confirms logic-level compatibility with -5 V or -10 V gate drivers; no 12 V required |
Pinout & Package
IRFU9214 uses the IPAK (TO-251) straight-lead through-hole package with drain-connected thermal tab. The case outline conforms to JEDEC TO-251AA, featuring 3 leads spaced on 2.29 mm (0.090") pitch, 8.89–9.65 mm body length, and 6.35–6.73 mm width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (left) | Source (S) | Reference node for gate drive; connects to system ground or low-side return path |
| Lead 2 (center) | Gate (G) | Control input; requires <14 nC charge for full enhancement; sensitive to ESD |
| Lead 3 (right) | Drain (D) | High-voltage output node; thermally bonded to case; must be isolated from PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche rated | 100 mJ single-pulse EAS enables robust operation in inductive switching without external clamping |
| P-channel topology | Eliminates need for high-side gate driver ICs in buck regulators and high-side switches |
| Straight-lead IPAK (TO-251) | Through-hole mounting provides mechanical stability and higher board-level vibration tolerance vs. surface-mount |
| Low Qgd/Qg ratio | 6.8/14 = 0.49 - Reduces Miller-induced shoot-through risk in half-bridge configurations |
| Body diode with controlled Qrr | 870–1300 nC reverse recovery charge - Supports moderate-frequency flyback and active clamp designs |
Applications
| Industrial Motor Control | High-Voltage DC-DC Converters |
|---|---|
|
Use Scenario: High-side switch in 24–48 V brushed DC motor H-bridge with regenerative braking. IC Role / Device Role / Timing Role: P-channel MOSFET controlling upper leg; handles bidirectional current during PWM-driven freewheeling. Use Value: -250 V rating accommodates back-EMF spikes up to 150 V; avalanche ruggedness prevents failure during abrupt load disconnection. |
Use Scenario: Primary-side switch in isolated 200 V input flyback converter for industrial PLC power supplies. IC Role / Device Role / Timing Role: Main switching element operating at 65–100 kHz; withstands reflected output voltage plus leakage spike. Use Value: 3.0 Ω RDS(on) limits conduction loss to <22 W at full load; 14 nC Qg enables efficient gate driving with low-power controllers. |
| AC-DC Power Supply Protection | Telecom Line Card Surge Switching |
|
Use Scenario: Inrush current limiter and overvoltage crowbar in 230 V AC front-end rectifier stage. IC Role / Device Role / Timing Role: High-side series switch placed between bridge rectifier and bulk capacitor; triggered during overvoltage events. Use Value: -250 V VDS exceeds peak rectified voltage (≈325 V) with margin; 100 mJ EAS absorbs surge energy without destruction. |
Use Scenario: Polarity protection and transient shunt in -48 V telecom line cards exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Reverse-polarity blocking switch and fast-acting crowbar for >1 kV differential transients. Use Value: Fast 11 ns turn-on delay and 14 ns rise time enable sub-microsecond response; drain-connected case simplifies thermal coupling to chassis ground. |
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 |
|---|---|---|---|
| IRFR9214 | Same silicon die, DPAK (TO-252) surface-mount package; RthJA = 50 °C/W (PCB mount) vs. 110 °C/W for IRFU9214 | Preferred for automated SMT assembly and compact layouts; lower thermal resistance with proper copper pour | Select IRFR9214 when board space is constrained and reflow soldering is available; IRFU9214 preferred for manual assembly or high-vibration environments |
| SiHFU9214 | Identical IPAK packaging and electrical specs; Pb-free/halogen-free construction per JEDEC J-STD-609A Class 2a | Required for RoHS-compliant industrial and telecom products; same thermal and switching performance | Choose SiHFU9214 for new designs targeting environmental compliance; IRFU9214 remains viable for legacy or non-RoHS programs |
Compared with IRFR9214 and SiHFU9214, the IRFU9214 offers identical electrical performance and ruggedness but prioritizes mechanical reliability via through-hole mounting-making it optimal where board flexure, thermal cycling, or serviceability demand physical lead retention over SMT density or RoHS mandates.

FAQ
What is the maximum continuous drain current for IRFU9214 at 100 °C case temperature?
The IRFU9214 supports -1.7 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK package; designers must ensure adequate heatsinking or airflow to maintain case temperature below 100 °C under sustained load.
Does IRFU9214 require a gate driver IC, or can it be driven directly from a microcontroller?
The IRFU9214 can be driven directly from a -5 V or -10 V logic source due to its VGS(th) range of -2.0 to -4.0 V, but microcontrollers with only 3.3 V or 5 V outputs cannot fully enhance it. A dedicated P-channel gate driver (e.g., TC4427 configured for high-side) or level-shifter is required for reliable switching at full RDS(on).
How does the avalanche rating of IRFU9214 impact circuit design?
The IRFU9214's 100 mJ single-pulse avalanche energy rating allows it to safely absorb inductive energy during unclamped turn-off events-such as relay coil de-energization or motor phase commutation-without external snubbers. Designers must verify pulse width and duty cycle stay within fig. 11 limits to avoid cumulative junction heating.
What is the thermal resistance from junction to ambient for IRFU9214 in typical PCB mounting?
The IRFU9214 has a maximum RthJA of 110 °C/W when mounted on a standard FR-4 PCB without added copper. With 1"² copper pad (per note a), RthJA improves to 50 °C/W-identical to the IRFR9214 DPAK variant-enabling higher power dissipation in thermally optimized layouts.
Can IRFU9214 replace IRFR9214 in an existing design without layout changes?
No-IRFU9214 uses straight-lead IPAK (TO-251) through-hole packaging, while IRFR9214 uses surface-mount DPAK (TO-252). The footprints, soldering methods, and mechanical mounting differ fundamentally; replacing one with the other requires PCB redesign, retooling, and validation of thermal and vibration performance.
