**STPS2L30** 

Datasheet 

## 30 V, 2 A low drop power Schottky rectifier 

## **Features** 

- Low forward voltage drop for less power dissipation 

- Optimized conduction/reverse losses trade-off which lead to the highest efficiency in the applications 

- Surface mount miniature package 

- Avalanche rated 

- ECOPACK2 component 

## **Applications** 

- Cordless appliance 

- SSD 

- Battery charger 

- Telecom power 

- DC / DC converter 

## **Description** 

Single chip Schottky rectifiers designed for high frequency miniature switched mode power supplies such as adaptors and on board DC/DC converters. 

Packaged in SMA, SMA Flat, SMA Flat Notch and SMB Flat, the STPS2L30 is ideal for use in parallel with MOSFETs in synchronous rectification.
