2SK4043LS

Overview

The onsemi 2SK4043LS is an N-channel silicon MOSFET designed as a general-purpose switching device. It features a drain-to-source voltage of 30 V and supports a continuous DC drain current of 20 A, with a pulsed current capability of 80 A. The component exhibits low ON-resistance, rated at a maximum of 21 mΩ at VGS=4V and 24 mΩ at VGS=2.5V. It operates with a gate-to-source voltage range of ±10 V and includes avalanche resistance guarantees, supporting single-pulse energies up to 147 mJ.

Feature Summary

Low ON-resistance for efficient power handling
Capable of operation with 2.5V drive signals
Guaranteed avalanche resistance for robust performance

Applications

Procurement Notes
