STMicroelectronics Intros STPS1150/2150/3150 Diodes

STMicroelectronics Inc. (ST, Geneva, Switzerland) introduced a series of 150 V Schottky diodes for use in the secondary rectification of fly-back power supplies in equipment such as DVD players, set-top boxes, Hi-Fi's and TVs.

The STPS1150, STPS2150 and STPS3150 are 150 V Schottky diodes that can handle continuous forward currents of up to 1 A, 2 and 3 A, respectively. The parts were designed for applications where a 100 V diode cannot be used and a 200 V part is more expensive, yet less efficient. The STPS1150, STPS2150 and STPS3150 offer a low VF for higher efficiency, a high maximum junction temperature of 175 °C and low leakage current.

The Schottky diodes are available in industry-standard, surface-mount (SMA and SMB) and axial-lead (DO-201AD, DO-15 and DO-41) packages. Prices range from $0.20 to $0.30 in quantities of 100,000 pieces.
