AOD242

Overview

The AOD242 is a 40V N-Channel MOSFET utilizing trench technology for high-frequency switching. It features an extremely low on-resistance of less than 5.8mΩ at VGS=10V and less than 8.2mΩ at VGS=4.5V. The device supports a continuous drain current of 5A and a pulsed current of 54A. Key electrical parameters include a gate threshold voltage range of 1.3V to 2.3V, total gate charge of 19nC to 28nC at 10V, and input capacitance of 1350pF. Thermal characteristics specify a junction-to-case resistance of 2.8°C/W and a maximum junction temperature of 175°C.

Feature Summary

Optimized trench MOSFET technology designed for efficient high-frequency switching performance.
Minimized conduction and switching power losses through low RDS(ON) combined with low Ciss and Coss values.
Manufactured with 100% UIS (Unclamped Inductive Switching) testing and 100% Rg (Gate Resistance) testing.

Applications

Boost converters
Synchronous rectifiers
Consumer power supplies
