ST’s portfolio of ultrafast diodes is qualified to the AEC-Q101 standard and is intended for DC-DC converters used in numerous automotive functions. These dedicated products are guaranteed in operation at junction temperatures from -40 °C up to +175 °C. The extension Y is used in the part number to identify the automotive version for a given rectifier.

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

EV, HEV go far with STTH3010-Y and STTH6010-Y

The new AEC-Q101-qualified 30-amp STTH3010-Y and 60-amp STTH6010-Y, are both 1000 V rated and housed in DO-247 package. Thanks to an excellent forward recovery time (tfr) of 450 ns and 750 ns respectively, while maintaining a low forward voltage of 1.3 V at the maximum average forward current, these very fast diodes significantly reduce the commutation losses in output rectification circuits. These perfectly fit EV and HEV boost circuitry.
