Product details
Overview
IRFR9214TRL from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount 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 fast switching, fully avalanche-rated ruggedness, and is used in high-voltage DC-DC converters, motor control H-bridge high-side switches, and industrial power supplies.
For engineers reviewing the IRFR9214TRL datasheet, IRFR9214TRL pinout, IRFR9214TRL application, or IRFR9214TRL equivalent, this device is selected for high-voltage P-channel switching where low gate charge (14 nC), robust unclamped inductive switching capability (100 mJ EAS), and thermal stability up to +150 °C junction temperature are critical design requirements.
Technical Context
This third-generation Vishay power MOSFET uses advanced silicon processing to achieve low on-resistance per die area while maintaining high breakdown integrity. Its P-channel architecture enables high-side switching without level-shifting circuitry in buck or half-bridge topologies.
The device features fully rated avalanche capability (EAS = 100 mJ), body diode with 150–220 ns reverse recovery time and 870–1300 nC Qrr, and gate charge profile optimized for efficient drive with standard -10 V logic-level gate drivers.

|---|---|
| VDS | -250 V - Supports high-voltage DC bus operation up to 250 V reverse polarity. |
| RDS(on) | 3.0 Ω @ VGS = -10 V - Enables low conduction loss in high-side switch applications at moderate current. |
| ID (continuous) | -2.7 A @ TC = 25 °C - Sustains typical load currents in industrial control and power conversion stages. |
| Qg | 14 nC - Reduces gate driver power demand and enables fast turn-on/turn-off transitions. |
| EAS | 100 mJ - Withstands repetitive unclamped inductive energy spikes without failure in motor drive or relay snubbing. |
| TJ range | -55 °C to +150 °C - Ensures reliable operation in harsh industrial and automotive under-hood environments. |
| RthJC | 2.5 °C/W - Allows effective heat transfer to PCB copper or heatsink for thermal management in surface-mount layouts. |

Applications
| High-Voltage DC-DC Converter | Industrial Motor Control |
|---|---|
Use Scenario: Step-down conversion from 200–240 V DC bus to 12–24 V for PLC I/O modules. IC Role / Device Role / Timing Role: High-side P-channel switch in synchronous buck topology, operating at 50–100 kHz. Use Value: -250 V VDS rating ensures margin against voltage transients; 3.0 Ω RDS(on) limits conduction loss at ≤2.5 A loads. |
Use Scenario: Bidirectional braking and direction control in 24–48 V brushed DC motors for factory automation. IC Role / Device Role / Timing Role: Upper-leg switch in H-bridge, commutated with precise dead-time control. Use Value: Fully rated avalanche capability absorbs inductive kickback during rapid PWM reversal; 150 ns trr minimizes cross-conduction risk. |
| AC-DC Auxiliary Power Supply | Overvoltage Protection Circuit |
Use Scenario: Standby auxiliary supply derived from main AC-DC converter output (e.g., 380 V DC link). IC Role / Device Role / Timing Role: P-channel MOSFET in active clamp or linear regulator stage for isolated bias winding. Use Value: -250 V VDS withstands peak line transients; -5.8 V VSD body diode drop enables efficient freewheeling during regulation cycles. |
Use Scenario: Crowbar-style overvoltage shutdown in telecom power systems monitoring ±48 V or 54 V rails. IC Role / Device Role / Timing Role: High-side disconnect switch triggered by comparator when rail exceeds threshold. Use Value: Fast turn-off (tf = 17 ns) ensures sub-microsecond response; 2.5 °C/W RthJC sustains short-circuit pulse without thermal runaway. |
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 |
|---|---|---|---|
| SiHFR9214-GE3 | Same silicon die, identical VDS, RDS(on), Qg, and avalanche rating; differs only in tape-and-reel packaging and RoHS compliance marking. | No functional difference; suitable for identical board-level use cases and layout. | Select SiHFR9214-GE3 for full Vishay Green-Compliant sourcing or alternate logistics channels. |
| IRFU9214PbF | Same electrical specs but IPAK (TO-251) through-hole package; higher RthJA (110 °C/W) and no exposed drain tab. | Requires through-hole assembly; less efficient thermal dissipation; unsuitable for high-density SMT designs. | Choose IRFU9214PbF only when legacy through-hole mounting or mechanical retention is required. |
Compared with IRFR9214TRL, SiHFR9214-GE3 offers identical performance in a functionally interchangeable package, while IRFU9214PbF trades surface-mount compatibility and thermal efficiency for through-hole mechanical robustness-making IRFR9214TRL optimal for space-constrained, thermally demanding SMT power stages.

FAQ
What is the maximum gate-source voltage rating for IRFR9214TRL?
The IRFR9214TRL has a gate-source voltage rating of ±20 V. Exceeding this limit risks permanent gate oxide damage. In practice, gate drive should be limited to -10 V for full enhancement and -5 V minimum for logic-level operation, as specified in the VGS(th) range of -2.0 V to -4.0 V. The IRFR9214TRL datasheet confirms this absolute maximum under "Absolute Maximum Ratings".
Can IRFR9214TRL be used in a synchronous rectifier configuration?
The IRFR9214TRL is not recommended for synchronous rectification due to its P-channel architecture and relatively high RDS(on) (3.0 Ω). Synchronous rectifiers require low forward voltage drop and fast reverse recovery; N-channel devices with sub-100 mΩ RDS(on) are preferred. The IRFR9214TRL body diode has VSD = -5.8 V and trr = 150–220 ns-too slow and lossy for efficient rectification. Use IRFR9214TRL instead for high-side switching roles.
What is the thermal resistance from junction to case (RthJC) for IRFR9214TRL?
The IRFR9214TRL has a maximum junction-to-case (drain) thermal resistance of 2.5 °C/W, as stated in the "Thermal Resistance Ratings" table of the Vishay datasheet (S21-0373-Rev. E). This value assumes proper soldering to a 1"² FR-4 PCB with adequate copper pour under the exposed drain tab. Actual thermal performance depends on PCB layout, copper thickness, and airflow.
Does IRFR9214TRL have avalanche capability, and how is it rated?
Yes, the IRFR9214TRL is fully avalanche rated with a single-pulse avalanche energy (EAS) of 100 mJ and repetitive avalanche current (IAR) of -2.7 A. These values are measured under standardized conditions (L = 27 mH, Rg = 25 Ω, starting TJ = 25 °C) and validated per Vishay's test methodology. This ruggedness allows safe operation in inductive switching applications without external snubbers.
What is the gate charge profile of IRFR9214TRL, and why does it matter?
The IRFR9214TRL has total gate charge (Qg) of 14 nC, gate-source charge (Qgs) of 3.1 nC, and gate-drain charge (Qgd) of 6.8 nC at VGS = -10 V. This profile determines switching speed and driver power requirements: low Qgd reduces Miller plateau duration, enabling faster turn-off; total Qg directly impacts gate driver IC selection and dynamic loss calculation in the IRFR9214TRL's operating circuit.
