STMicroelectronics has introduced a family of power rectifiers that will help product manufacturers achieve energy-efficiency approvals, such as 80 PLUS. The STPS50U100C is a rectifier diode and can be used in the output of power supplies for adapters, desktop PCs, servers, TV and video products, communication equipment, and many other electrical appliances.
It is the first member of a new family of ultra-low forward voltage (ULVF) Schottky rectifier diodes from ST, which will provide a range of diode properties to fulfill various applications. The forward voltage drop is the main source of power losses in power Schottky diodes used for secondary rectification, therefore minimizing this voltage drop is a key innovation driver.
Package options will include TO-220 and I2PAK, with other styles planned to be made available in the future. The STPS50U100C is in full production now, in TO-220 (STPS50U100CT) and I2PAK (STPS50U100CR) package options, respectively, priced from $1.50 in quantities of 1000 pieces.
