Description

This MOSFET is designed to minimize the on-state resistance (R_DS(ON)) 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
Low R_DS(ON)– Ensures On-State Losses are Minimized
Excellent Q_gd x R_DS(ON)Product (FOM)
Wettable Flank for Improved Optical Inspection
100% Unclamped Inductive Switching (UIS) Test in Production – Ensures More Reliable and Robust End Application
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/

Application(s)

Backlighting
Power-management functions
DC-DC converters
