## Power Schottky rectifier 

**Datasheet** - **production data** 

## **Description** 

Single Schottky rectifier suited for switch mode power supplies and high frequency DC to DC converters. 

Packaged in STmite, this device is intended for use in low voltage, high frequency inverters, free wheeling and polarity protection applications. Due to the small size of the package this device fits battery powered equipment (cellular, notebook, PDA’s, printers) as well chargers and PCMCIA cards. 

**Table 1. Device summary** 

## **Features** 

- Very small conduction losses 

- Negligible switching losses 

- Extremely fast switching
