Product details

Overview

IRFU9024 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, 0.28 Ω R_DS(on) at V_GS = -10 V, and -8.8 A continuous drain current at T_C = 25 °C. It delivers fast switching, repetitive avalanche capability, and robust dV/dt immunity for DC-DC converter high-side switches and motor control H-bridge legs.

For engineers reviewing the IRFU9024 datasheet, IRFU9024 pinout, IRFU9024 application, or IRFU9024 equivalent, this page provides verified package mapping, validated thermal and dynamic parameters, confirmed through-hole mounting configuration, and real-world design context for industrial power stage implementation.

Technical Context

This device operates as a normally-off P-channel switch with gate-source threshold voltage between -2.0 V and -4.0 V, enabling direct logic-level drive compatibility when paired with appropriate level-shifting or gate driver circuitry. Its 19 nC total gate charge and 5.4 nC gate-source charge support efficient switching up to several hundred kHz in hard-switched topologies.

The IRFU9024 integrates a fast-recovery body diode with 100–200 ns reverse recovery time and 0.32–0.64 μC Q_rr, making it suitable for synchronous rectification and freewheeling paths where controlled diode conduction is required. Its 3.0 °C/W junction-to-case thermal resistance enables effective heat transfer to PCB copper or external heatsinks in through-hole layouts.

FAQ

What is the maximum continuous drain current rating for IRFU9024 at 100 °C case temperature?

The IRFU9024 has a continuous drain current rating of -5.6 A at T_C = 100 °C, derived from its 42 W maximum power dissipation and thermal derating factor of 0.33 W/°C above 25 °C. This value reflects safe operation with adequate heatsinking in through-hole mounted configurations where case temperature is actively managed.

Does IRFU9024 support logic-level gate drive without a dedicated gate driver IC?

The IRFU9024 has a gate-source threshold voltage range of -2.0 V to -4.0 V, meaning it begins conducting at relatively low negative gate voltages. However, full enhancement to achieve specified R_DS(on) requires V_GS = -10 V. Therefore, while partial turn-on occurs with logic-level signals, reliable low-loss operation of IRFU9024 demands a gate driver capable of delivering at least -10 V swing.

What is the thermal resistance from junction to ambient for IRFU9024 in a standard PCB mount configuration?

In a standard 1" square FR-4 PCB mount, the IRFU9024 exhibits a maximum junction-to-ambient thermal resistance (R_thJA) of 50 °C/W. This value assumes no additional heatsink and accounts for conduction through leads and copper pour. For higher power operation, thermal design must consider this limit to ensure T_J remains below 150 °C.

Can IRFU9024 be used in avalanche mode for energy clamping in inductive load circuits?

Yes, the IRFU9024 is explicitly rated for repetitive avalanche operation with 5.0 mJ per pulse and single-pulse capability up to 300 mJ. Its datasheet includes test conditions and waveforms validating this behavior, making IRFU9024 suitable for clamping inductive kickback in relay drivers, solenoid controls, and motor phase switching without external snubbers.

What is the body diode forward voltage of IRFU9024 at -8.8 A and 25 °C?

The body diode forward voltage (V_SD) of IRFU9024 is -6.3 V at T_J = 25 °C, I_S = -8.8 A, and V_GS = 0 V. This relatively high forward drop reflects its optimization for switching rather than diode conduction, and designers should account for this loss in freewheeling paths or consider synchronous rectification strategies.
