The extremely low profile and light weight of STMicroelectronics‘ latest automotive-qualified high-voltage ultrafast rectifiers support space-efficient vehicle electronics by helping miniaturize electronic control modules, power converters, and motor drives. The new rectifiers are packaged as SMBFlat devices that weigh only 50mg and, at 1mm-thick, are almost 60% thinner than the nearest competing rectifiers in standard 2.4mm-thick SMB packages. This helps designers create lighter and slimmer Electronic Control Units suitable for mounting in small spaces within the vehicle. The two-lead surface-mount SMBFlat package is footprint-compatible with standard SMB devices, which promotes ease of use in existing PC-board designs.

With their wide temperature range of -40 to 175 degrees C, ST’s SMBFlat rectifiers suit both automotive applications and equipment installed in harsh environments, such as mobile base stations and outdoor lighting. The 10 ultrafast rectifiers introduced today have current ratings from 1A to 3A and repetitive peak reverse voltage ratings from 600V to 1200V.
