2SK3934

Product Overview

2SK3934 is a Toshiba silicon N-channel power MOSFET based on π-MOSVI technology and designed primarily for switching regulator applications. The device provides a 500V drain-source voltage rating, 15A continuous drain current capability and low drain-source on-resistance for efficient power switching. With high forward transfer admittance, low leakage current and enhancement-mode operation, 2SK3934 is suitable for switch-mode power supplies, DC-DC converters, industrial power control and other high-voltage switching circuits. Its JEITA SC-67 / Toshiba 2-10U1B package supports through-hole mounting and effective thermal management.
