STPS140Z is a Schottky diode from ST company. Its main features are very small conduction losses, negligible switching losses and extremely fast switching. The device is intended for use in switchmode power supplies and high frequency DC to DC converters.
The STPS140Z is a single Schottky rectifier packaged in SOD-123, intended for use in low voltage, high frequency inverters, free wheeling, and polarity protection applications. It is designed for GSM and PCMCIA requirements due to its small size.
Key electrical characteristics include a repetitive peak reverse voltage of 40 V and a continuous forward current of 1 A at Tamb = 60 °C. The device features very small conduction losses and negligible switching losses, with a maximum operating junction temperature of 150°C.
