The IRFU420 is an N-Channel Power MOSFET from Vishay Siliconix. It is rated for a drain-to-source voltage (Vds) of 500 V and a maximum continuous drain current of 2.4 A at Tc = 25 °C. The device has a maximum on-resistance of 3 Ω at Id = 1.4 A and Vgs = 10 V. Gate charge parameters include a total gate charge (Qg) of 19 nC maximum, with typical Qgs of 3.3 nC and Qgd of 13 nC.
This MOSFET features fast switching, a dynamic dV/dt rating, and repetitive avalanche capability, making it suitable for robust power switching designs. Single pulse avalanche energy is rated up to 400 mJ, and repetitive avalanche energy up to 4.2 mJ. Maximum power dissipation is 42 W at case temperature 25 °C, or 2.5 W when PCB-mounted at 25 °C ambient. The device operates over a junction temperature range of -55 °C to +150 °C.
The IRFU420 is supplied in a TO-251-3 Short Leads (IPak, TO-251AA) package for through-hole mounting. It is part of the IRFR420/IRFU420 series and is also available as SiHFU420. The device is intended for applications requiring high-voltage switching with low on-resistance and ruggedized performance.
