150-V Schottky’s proclaim efficiency edge in consumer supplies

Lexington, Mass. – Touting high efficiency and a maximum junction temperature of 175&degC, STMicroelectronics’ STPS1150, STPS2150 and STPS3150 Schottky diodes, rated at 150 volts, are designed for use in flyback power supplies (on up to 24-volt rails) serving DVD players, set-top boxes, TVs and Hi-Fi equipment. The parts are suited for applications where a 100-volt diode cannot be used and a 200-volt part is more expensive, yet less efficient.
