ST Life.augmented

Automotive-grade ultrafast diodes

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.

Super-slim AEC-Q101-qualified ultrafast rectifiers

ST extends its range of ultrafast rectifiers dedicated to automotive applications housed in slim packages 60% thinner than the standard SMA and SMB packages yet footprint compatible:

- High-voltage ultrafast rectifiers (600 V to 1200 V) in SMBFlat – 50 mg, 1 mm thick – with a current rating from 1 A to 3 A,
- 200 V ultrafast rectifiers in SOD128-Flat – 26 mg, 1mm thick – as STTH2R02A-Y and STTH3R02A-Y (2 and 3A).

This flat-package rectifier range enables the design of lighter and slimmer ECUs as well as use in existing designs, including L-series devices with low forward voltage (VF) for circuits requiring low conduction losses, and R-series devices with lower reverse-recovery time (trr) permitting the use of smaller external inductors and capacitors at higher operating frequencies.

Thanks to the Tj range from -40 °C to 175 °C, these rectifiers are ideal for miniature automotive electronic control modules, power converters, motor drives, and freewheeling diodes.
They can also be designed in equipments in harsh industrial environments, such as mobile base stations and outdoor lighting.
