Automotive surge protection devices are 'industry's first'

Aiming to help vehicle electronics manufacturers deliver safer, more reliable systems, STMicroelectronics has launched the first ever protection devices certified to the automotive industry's preferred specifications

By saving the time needed for independent certification, the transient voltage suppressors are said to enable new products to reach the market more quickly and at more competitive prices. In addition, the SM4TY-SM30TY series of Transil miniature devices are certified to pulse specifications used by the automotive industry. They are also qualified to the AEC-Q101 automotive reliability test standard for discrete semiconductors, and have a full Automotive-Grade Approval Certificate (AGAC). The Transil protection devices are housed in miniature surface mount power packages occupying from 12.8mm2 to 46mm2 of pc board space, capable of handling from 400 to 3000W of power contained in pulses and ESD transients present on the vehicle wiring. The devices are in mass production now and are available in SMA, SMB or SMC surface mount packages.
