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.

On-board chargers (OBC) now enjoy our new 600V ‘RQ’ diodes with improved creepage distance and new high-voltage D²PAK

ST now offers new 600V ‘RQ’ diodes (Rapid & Quiet) developed for on-board battery chargers (OBC) and 2- or 3-wheeler battery chargers. Their high-voltage D²PAK package improves the creepage distance between the anode and cathode from 1.38 mm for standard D²PAK devices to a minimum of 3.48 mm. 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. With forward current ratings ranging from 15 up to 30 A, ST’s STTH15RQ06G2 and STTH30RQ06G2 ultrafast diodes are available in surface-mount, high voltage D²PAK packages in both industrial-grade and AEC-Q101-qualified automotive-grade versions.
