Product details

Overview

IRFR9214TR 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 on-resistance at V_GS = -10 V, and -2.7 A continuous drain current at T_C = 25 °C. It delivers fast switching with 14 nC total gate charge and is fully avalanche-rated for robustness in inductive load switching applications such as DC motor control and high-voltage power supplies.

For engineers reviewing the IRFR9214TR datasheet, IRFR9214TR pinout, IRFR9214TR application, or IRFR9214TR equivalent, key selection criteria include its -250 V blocking capability, DPAK thermal performance (R_thJC = 2.5 °C/W), body diode recovery characteristics (t_rr = 150–220 ns), and compatibility with standard surface-mount reflow processes.

Technical Context

This device employs third-generation silicon process technology to achieve low R_DS(on) per die area while maintaining rugged avalanche performance. Its P-channel topology enables high-side switching without level-shifting circuitry in buck regulators and polarity-reversal circuits.

The MOSFET features an integral reverse p-n junction body diode with V_SD = -5.8 V at I_S = -2.7 A and Q_rr = 870–1300 nC, supporting controlled commutation in flyback and synchronous rectification topologies where diode conduction occurs during dead time.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-250 V - Supports high-voltage DC bus isolation up to 250 V reverse polarity.
R_DS(on)	3.0 Ω @ V_GS = -10 V - Enables <1.5 W conduction loss at -1.7 A, suitable for medium-power switching.
I_D (continuous)	-2.7 A @ T_C = 25 °C - Delivers stable current handling with PCB heatsinking.
Q_g	14 nC - Determines gate drive energy requirement; compatible with standard logic-level drivers.
E_AS	100 mJ - Withstands single-pulse inductive energy without failure in unclamped switching events.
R_thJC	2.5 °C/W - Enables efficient heat transfer to external heatsink via DPAK drain tab.
t_rr	150–220 ns - Limits switching losses during body diode commutation in hard-switched converters.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection; lead (Pb)-free and halogen-free construction per RoHS.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Reference node for gate drive; connects to load return or ground in high-side configuration.
Pin 2 (Gate)	Control input	Receives negative gate voltage relative to source to turn on; threshold range -2.0 to -4.0 V.
Pin 3 (Drain)	Power output	High-voltage switching node; electrically and thermally connected to exposed metal tab.

Key Features

Feature	Design Value
Fully avalanche-rated	100 mJ single-pulse E_AS ensures reliability under inductive fault conditions without external snubbers.
P-channel topology	Enables high-side switching with simple gate drive referenced to source, eliminating level shifters in buck controllers.
Low R_DS(on) × Q_g figure-of-merit	3.0 Ω × 14 nC = 42 Ω·nC - Balances conduction and switching losses for 100–500 kHz operation.
Fast body diode recovery	t_rr = 150–220 ns and Q_rr = 870–1300 nC reduce voltage overshoot and ringing in freewheeling paths.
DPAK thermal design	R_thJC = 2.5 °C/W allows >50 W power dissipation with minimal heatsink when mounted on copper pour.

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
SiHFR9214TR-GE3	Same die, identical R_DS(on), Q_g, and avalanche rating; differs only in Vishay's internal part numbering and tape/reel packaging.	No functional difference; direct second-source for supply chain diversification.	Select when requiring Vishay's GE3-compliant packaging or alternate logistics labeling.
IRFU9214PbF	Same silicon but IPAK (TO-251) through-hole package; R_thJA = 50 °C/W vs. 110 °C/W for DPAK; same electrical specs.	Used where manual assembly or higher board-level mechanical stability is required; not surface-mount compatible.	Choose for legacy through-hole designs or where DPAK thermal constraints exceed PCB layout capability.

Compared with IRFR9214TR, SiHFR9214TR-GE3 offers identical electrical and thermal performance with alternate packaging compliance, while IRFU9214PbF provides identical silicon in a through-hole variant-neither is pin-compatible due to differing package footprints, but both serve the same high-voltage P-channel switching function.

FAQ

What is the maximum continuous drain current for IRFR9214TR at 100 °C case temperature?

The IRFR9214TR supports -1.7 A continuous drain current at T_C = 100 °C, reflecting linear derating from -2.7 A at 25 °C using the specified 0.40 W/°C factor. This value is validated under standard PCB mount conditions and must be verified against actual board thermal design for the target application.

Does IRFR9214TR require a negative gate drive voltage, and what is its threshold range?

Yes, IRFR9214TR is a P-channel MOSFET and requires a gate voltage more negative than the source to turn on. Its gate-source threshold voltage V_GS(th) ranges from -2.0 V to -4.0 V at I_D = -250 μA, meaning reliable enhancement-mode operation begins at approximately -3 V and is fully enhanced at -10 V.

Can IRFR9214TR be used in avalanche mode, and what is its single-pulse energy rating?

Yes, IRFR9214TR is fully avalanche-rated with a single-pulse avalanche energy E_AS of 100 mJ under defined test conditions (L = 27 mH, R_g = 25 Ω, I_AS = -2.7 A). This rating applies to unclamped inductive switching events and is validated per JEDEC standards in the official datasheet.

What is the thermal resistance from junction to case (R_thJC) for IRFR9214TR, and how does it impact heatsinking?

The IRFR9214TR has a maximum junction-to-case thermal resistance R_thJC of 2.5 °C/W, measured from die to the exposed drain tab. This low value enables efficient heat transfer to an external heatsink or copper pour, supporting >50 W power dissipation when properly mounted-critical for sustained high-current operation in power supplies.

Is IRFR9214TR compatible with lead-free reflow soldering, and what peak temperature is recommended?

Yes, IRFR9214TR is lead (Pb)-free and halogen-free, qualified for lead-free reflow soldering. The datasheet specifies a peak soldering temperature of 260 °C for 10 seconds, consistent with IPC/JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly.
