Product details

Overview

IRFU020 from Vishay Siliconix is a 60 V, 14 A N-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, featuring 0.10 Ω R_DS(on) at V_GS = 10 V, 25 nC total gate charge, and 91 mJ single-pulse avalanche energy-designed for DC-DC converters, motor control, and load switching in industrial power supplies.

For engineers reviewing the IRFU020 datasheet, IRFU020 pinout, IRFU020 application, or IRFU020 equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics, PCB-mount power dissipation limits, and validated alternative parts for high-current switching designs requiring ruggedized discrete FETs.

Technical Context

The IRFU020 employs third-generation trench-gate silicon technology optimized for fast switching with low conduction loss and high dV/dt immunity (5.5 V/ns). Its gate threshold voltage (2.0–4.0 V) supports standard 10 V logic-level drive while maintaining robust noise margin.

Thermal design relies on junction-to-case resistance of 3.0 °C/W and junction-to-ambient of 50 °C/W when mounted on a 1" FR-4 PCB. The integrated body diode exhibits 88–180 ns reverse recovery time and 0.29–0.64 μC Q_rr, enabling reliable operation in synchronous rectification and inductive load switching.

FAQ

What is the maximum continuous drain current for IRFU020 at 100 °C case temperature?

The IRFU020 supports 9.0 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limitations under real-world heatsink conditions and must be used-not the 14 A rating at 25 °C-for thermal design validation in sustained operation.

Does IRFU020 have an integrated body diode, and what are its key recovery parameters?

Yes, IRFU020 includes an integral body diode rated for 14 A continuous source-drain current. Its reverse recovery time (t_rr) is 88–180 ns and reverse recovery charge (Q_rr) is 0.29–0.64 μC at T_J = 25 °C, IF = 17 A, and dI/dt = 100 A/μs-critical parameters for minimizing switching loss in freewheeling and synchronous rectification topologies.

What is the gate threshold voltage range for IRFU020, and how does it affect drive compatibility?

The IRFU020 has a gate-source threshold voltage (V_GS(th)) range of 2.0–4.0 V at I_D = 250 μA. This allows reliable turn-on with standard 5 V or 3.3 V logic-level drivers while maintaining sufficient noise margin against spurious triggering in electrically noisy industrial environments.

Can IRFU020 be used in avalanche mode, and what is its rated single-pulse energy?

Yes, IRFU020 is rated for repetitive unclamped inductive switching with a single-pulse avalanche energy (E_AS) of 91 mJ under defined test conditions (V_DD = 25 V, L = 541 μH, I_AS = 14 A). This capability supports robust operation in relay driving, solenoid control, and snubberless flyback converters without external protection.

What package type and thermal characteristics define IRFU020's PCB-level thermal performance?

IRFU020 uses the DPAK (TO-252) surface-mount package with an exposed drain pad. Its junction-to-ambient thermal resistance is 50 °C/W when mounted on a 1" square FR-4 PCB-enabling 2.5 W power dissipation at ambient temperature-while junction-to-case resistance is 3.0 °C/W for direct heatsink attachment.
