Product details

Overview

IRFU9014 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in straight-lead (through-hole) IPAK (TO-251) package, rated for -60 V drain-source voltage, 0.50 Ω R_DS(on) at V_GS = -10 V, and -5.1 A continuous drain current at T_C = 25 °C. It delivers fast switching, repetitive avalanche capability, and dynamic dV/dt rating for robust operation in DC-DC converters and motor control circuits.

For engineers reviewing the IRFU9014 datasheet, IRFU9014 pinout, IRFU9014 application, or IRFU9014 equivalent, key selection considerations include its through-hole mounting configuration, -60 V blocking capability, 0.50 Ω on-resistance at -10 V gate drive, avalanche energy rating of 2.5 mJ, and compatibility with standard logic-level gate drivers in high-side switch topologies.

Technical Context

This device employs a third-generation trench-gate silicon process optimized for low R_DS(on) and fast switching transitions. Its P-channel architecture enables high-side switching without level-shifting circuitry, and its integrated body diode supports synchronous rectification and freewheeling in buck and H-bridge configurations.

The IRFU9014 features a specified peak diode recovery dV/dt of -4.5 V/ns and a body diode reverse recovery time of 80–160 ns, confirming suitability for moderate-frequency hard-switched applications up to ~100 kHz. Thermal resistance R_thJC is 5.0 °C/W, enabling 25 W power dissipation when mounted on a heatsink.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - Maximum blocking voltage for high-side DC-DC and load switch designs
R_DS(on) @ V_GS = -10 V	0.50 Ω - Enables ≤1.3 W conduction loss at -3.1 A continuous current
I_D (continuous, T_C = 25 °C)	-5.1 A - Supports medium-power loads such as 12 V/24 V industrial actuators
Q_g (max)	12 nC - Determines gate driver current requirement (~1.2 mA avg. at 100 kHz)
E_AR (repetitive avalanche)	2.5 mJ - Confirms reliable unclamped inductive switching in relay/motor drive snubbers
T_J range	-55 to +150 °C - Validated for under-hood automotive and industrial ambient environments
dV/dt (peak diode recovery)	-4.5 V/ns - Limits parasitic turn-on risk during body diode commutation

Pinout & Package

The IRFU9014 uses the IPAK (TO-251) straight-lead through-hole package with three terminals: Drain (D), Gate (G), and Source (S). The drain tab is electrically connected to the die substrate and serves as the primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current-carrying terminal (high-side connection point)	Electrically and thermally tied to metal tab; requires isolation from heatsink unless referenced to system ground
Gate (G)	Control input for channel conduction	Requires ≥\|2.0 V\| threshold voltage; driven negative relative to source to turn on; gate charge Q_g = 12 nC
Source (S)	Reference node for gate drive and current return path	Connected to positive rail in high-side switch; defines V_GS reference; carries full load current

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation in inductive load switching without external snubbers (E_AR = 2.5 mJ)
P-channel enhancement mode	Allows direct high-side switching with simple gate drive referenced to load supply rail
Dynamic dV/dt rating	Guarantees immunity to false turn-on during fast voltage transients across drain-source (−4.5 V/ns)
Through-hole (straight-lead) IPAK	Provides mechanical robustness and thermal reliability in high-vibration or high-reliability PCB assemblies
Fast switching with low Q_gd	Q_gd = 5.1 nC minimizes Miller plateau duration, reducing switching losses in PWM applications

FAQ

What is the maximum continuous drain current for IRFU9014 at 100 °C case temperature?

The IRFU9014 supports -3.2 A continuous drain current at T_C = 100 °C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK package; designers must ensure adequate heatsinking or PCB copper area to maintain junction temperature below 150 °C under sustained load conditions. The linear derating factor is 0.20 W/°C above 25 °C case temperature.

Does IRFU9014 require a negative gate drive voltage to operate?

Yes, the IRFU9014 is a P-channel MOSFET and requires a gate voltage more negative than the source to turn on. A V_GS of -10 V fully enhances the channel, delivering 0.50 Ω R_DS(on); the gate-source threshold voltage ranges from -2.0 V to -4.0 V. For logic-level compatibility, gate drivers capable of sinking current to pull the gate below source potential are required.

Can IRFU9014 be used in avalanche mode repeatedly?

Yes, the IRFU9014 is explicitly rated for repetitive avalanche operation with E_AR = 2.5 mJ and I_AR = -5.1 A, provided pulse width and duty cycle remain within limits defined in Figure 11 of the datasheet. This capability allows safe operation in inductive switching applications like relay driving without external clamping components.

What is the thermal resistance from junction to case (R_thJC) for IRFU9014?

The IRFU9014 has a maximum junction-to-case (drain) thermal resistance of 5.0 °C/W, measured from the silicon die to the exposed drain tab. This value assumes proper mechanical mounting to a heatsink with thermal interface material; it enables 25 W power dissipation when T_C is held at 25 °C, making it suitable for medium-power through-hole applications with passive or forced-air cooling.

Is IRFU9014 compatible with automated through-hole assembly processes?

Yes, the IRFU9014's straight-lead IPAK (TO-251) package is designed for wave soldering and vapor-phase reflow compatible with standard through-hole assembly lines. Lead spacing and coplanarity meet IPC-A-610 Class 2 requirements, and the device is qualified for peak solder temperatures up to 260 °C for 10 seconds, supporting high-yield manufacturing in industrial and automotive production environments.
