ST’s portfolio of Schottky diodes is fully compliant with the AEC-Q101 standard and is intended for DC-DC converters. They are used in numerous automotive functions such as LDC (Low Voltage DC-DC), as well as in secondary rectification, OBC, LLC, forward active clamp or phase shift circuits. These dedicated products are functional at junction temperatures as low as -40 °C and as high as +175 °C for most of them. The extension Y is used in the part number to identify the automotive-grade  version for a given rectifier.

A special test screening matrix is implemented on these automotive-grade products at die and finished product levels, in order to comply with the automotive quality requirements. The automotive-grade schottky diodes belong to our STPOWER family.

STMicroelectronics provides tools which allow designers to quickly find the field-effect rectifier or Schottky diode that best fits their application using our online Schottky & FERD eTool simulator and diode product finder application for Android and iOS.

Recent 30 to 60 V dual Schottky rectifiers in PSMC (TO-277A) will be used in automotive grade high-performance DC/DC converters through the integration of rectification and freewheeling diode into the same package, and in enhanced reverse polarity protection functions.
