Product details

Overview

IRFU9010 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in IPAK (TO-251) package, rated for -50 V drain-source voltage, 0.50 Ω R_DS(on) at V_GS = -10 V, and -5.3 A continuous drain current at T_C = 25 °C. It delivers robust avalanche capability (136 mJ single-pulse), fast switching (t_d(off) ≤ 20 ns), and high dV/dt immunity (5.8 V/ns), making it suitable for DC/DC converter high-side switches and load switching in telecom power supplies.

For engineers reviewing the IRFU9010 datasheet, IRFU9010 pinout, IRFU9010 application, or IRFU9010 equivalent, key selection considerations include its straight-lead IPAK thermal performance (R_thJC = 5.0 °C/W), body diode recovery characteristics (t_rr = 33–160 ns), gate charge profile (Q_g = 9.1 nC max), and compatibility with -10 V gate drive in industrial low-voltage power management circuits.

Technical Context

This device uses Vishay's advanced trench MOSFET process to achieve low on-resistance while maintaining high transconductance (g_fs = 1.7 S typ) and stable threshold voltage (-2.0 to -4.0 V). Its design supports repetitive avalanche operation and features integrated body diode with controlled reverse recovery (Q_rr = 0.090–0.52 μC).

The IRFU9010 operates as a high-side switch in buck converters and hot-swap controllers, where its negative V_GS(th) enables simple level-shifting gate control and its low C_iss (240 pF typ) reduces drive power requirements. Thermal design relies on direct heatsink mounting via the exposed drain pad per TO-251AA mechanical specification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-50 V - Maximum blocking voltage for low-voltage DC bus applications
R_DS(on) @ V_GS = -10 V	0.50 Ω max - Enables <1.4 W conduction loss at -2.8 A, critical for thermally constrained PCBs
Q_g	9.1 nC max - Determines gate driver current requirement (~1.8 mA avg for 500 kHz switching)
I_D (continuous)	-5.3 A @ T_C = 25 °C - Defines maximum steady-state load current with heatsink
E_AS	136 mJ - Supports unclamped inductive turn-off without failure in flyback or synchronous rectifier snubbers
dV/dt rating	5.8 V/ns - Ensures noise immunity during fast transient events in motor drive half-bridges
t_r/t_f	47–71 ns / 35–59 ns - Enables efficient 200–500 kHz switching in isolated DC/DC topologies

Pinout & Package

IRFU9010 uses the IPAK (TO-251AA) straight-lead package with exposed drain pad for thermal conduction. The package measures 8.89 × 6.35 mm (L × E), has 3 leads, and requires minimum 4.32 mm E1 pad width for heatsink attachment per Vishay drawing 91362.

FAQ

What is the maximum continuous drain current rating for IRFU9010 at 100 °C case temperature?

The IRFU9010 supports -3.3 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK package; designers must ensure adequate heatsinking to maintain junction temperature below 150 °C under sustained load. The linear derating factor is 0.20 W/°C above 25 °C case temperature.

Does IRFU9010 have a specified avalanche energy rating, and how is it tested?

Yes, IRFU9010 is rated for 136 mJ single-pulse avalanche energy (E_AS) under test conditions of V_DD = -25 V, starting T_J = 25 °C, L = 9.7 mH, R_g = 25 Ω, and peak I_L = -5.3 A. This rating confirms capability to absorb inductive switching energy without failure, validated per JEDEC JESD24-11 methodology.

What is the gate-source threshold voltage range for IRFU9010, and why does it matter for logic-level drive?

The IRFU9010 has a V_GS(th) range of -2.0 V to -4.0 V at T_J = 25 °C. This wide threshold enables reliable turn-on with standard 5 V logic-level signals (since |V_GS| > |V_GS(th)|), but designers must verify sufficient overdrive (≥ -10 V recommended) to achieve the specified 0.50 Ω R_DS(on) and avoid operating in the linear region.

How does the body diode performance of IRFU9010 compare to standard rectifiers in synchronous rectification?

The IRFU9010 body diode exhibits t_rr = 33–160 ns and Q_rr = 0.090–0.52 μC, significantly faster than general-purpose rectifiers. This enables efficient synchronous rectification in buck converters, reducing reverse recovery losses and EMI. However, its V_SD = -5.5 V at -5.3 A means it is not optimized for low forward drop-external Schottky diodes may be preferred for ultra-low-loss designs.

Is IRFU9010 pin-compatible with IRFR9010, and what is the key mechanical difference?

No, IRFU9010 is not pin-compatible with IRFR9010. IRFU9010 uses the IPAK (TO-251) straight-lead package with three inline leads and an exposed drain pad on the bottom, while IRFR9010 uses the DPAK (TO-252) surface-mount package with gull-wing leads. The footprint, soldering method, and thermal mounting approach differ fundamentally-PCB layout and assembly processes are not interchangeable.
