Description

This MOSFET is designed to minimize the on-state resistance (R_DS(ON)) and yet maintain superior switching performance, making it ideal for high efficiency power management applications.

Feature(s)

Rated to +175°C – Ideal for High Ambient Temperature Environments
100% Unclamped Inductive Switching – Ensures More Reliable and Robust End Application
Low R_DS(ON) – Ensures On-State Losses are Minimized
Excellent Q_GD x R_DS(ON) Product (FOM)

Application(s)

Power Management Functions
DC-DC Converters
Backlighting
