AOB256L

Overview

The AOB256L is a 150V N-Channel MOSFET utilizing trench technology optimized for high-frequency switching. It features a maximum drain-source voltage of 150V and a continuous drain current of 35A at 25°C case temperature. The device offers an on-resistance of less than 85mΩ at VGS=10V and less than 100mΩ at VGS=4.5V. Total gate charge is 22nC at 10V. It operates within a junction temperature range of -55°C to 175°C and is housed in a TO-263 (D2PAK) package.

Feature Summary
