ST’s portfolio of bridge rectifier diodes – AEC-Q101-qualified – is intended for primary bridges used in automotive battery chargers. These dedicated products are guaranteed in operation at junction temperatures from -40 up to +175 °C. The bridge rectifier diodes belong to our STPOWER family.

A special screening matrix is implemented on these automotive-grade products at both die and finished product levels, in order to comply with the most stringent international automotive quality requirements.

The new 800 V series, available in 30 A (STBR3008-Y) and 60 A (STBR6008-Y) versions, provides up to 200 mV lower forward voltage compared to the 1200 V series. Lowering by 5 W the power consumption in a 11kW on-board charger (OBC) reduces the operating junction temperature by 15 °C. This important thermal stress reduction contributes to increase the reliability of heavy duty applications such as on-board chargers, charging stations, and renewable energy converters.
