## **Features** - Negligible switching losses - Low forward voltage drop for higher efficiency and extended battery life 150 V Power Schottky rectifier are suited for switch mode power supplies on up to 24 V rails and high frequency converters. Packaged in Axial, SMB, and low-profile SMB, this device is intended for use in consumer and computer applications like TV, STB, PC and DVD where low drop forward voltage is required to reduce power dissipation. **Table 1.
