High-temperature power Schottky diodes feature low leakage current

The STPSTxH100xx power Schottky diodes from STMicroelectronics are based on trench technology which optimizes the forward voltage/reverse current trade-off for a given silicon die area.

STMicroelectronics supplies a wide range of 100 V high-temperature power Schottky diodes with current ratings ranging from 1 A to 15 A. 

The STPSTxH100xx series diodes, which are notable for their very low leakage current, are supplied in flat, space-saving packages. This makes them ideal for use in high-frequency miniature switch-mode power supplies. 

All diodes in the high-temperature range have a maximum operating temperature of 175°C. The diodes provide a very wide guard band to protect against thermal runaway in the application.

Designing with the ST power Schottky diodes is supported by the eDesignSuite, a comprehensive set of easy-to-use utilities for streamlining system development. The suite’s Rectifier Diodes Simulator enables the designer to: 

  • Select ratings and application waveforms
  • Estimate power losses
  • Search and sort suitable devices
