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.

OCB and EV charging station gain efficiency with STTH60RQ06-Y

ST now offers new 600V ‘RQ’ diodes (Rapid & Quiet), developed for on-board battery chargers (OBC), 2- or 3-wheeler battery chargers, electric vehicle (EV) charging stations, and industrial converters. These diodes feature a specific V RRM guaranteed from -40 to +175 °C, a unique trade-off between a soft reverse recovery to reduce electromagnetic interference (EMI), and a low forward voltage (V F) to gain efficiency in all modes of resonant-based topologies. Ranging now from 15 up to 60 A forward current ratings, ST’s STTH15RQ06(-Y), STTH30RQ06(-Y), and STTH60RQ06(-Y) are available in surface-mount (D²PAK) and through-hole (TO-220AC and DO-247) packages, in both industrial grade and AEC-Q101-qualified automotive grade.
