Description

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

Feature(s)

Low RDS(ON) – Minimizes On-State Losses
Excellent Qgd x RDS(ON) Product (FOM)
Advanced Technology for DC-DC Converters
Small Form Factor Thermally Efficient Package Enables Higher Density End Products
100% Unclamped Inductive Switching (UIS) Test in Production – Ensures More Reliable and Robust End Application
Totally Lead-Free & Fully RoHS Compliant
Halogen and Antimony Free. “Green” Device
For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, 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
