STM automotive TVS devices are ISO-certified
Test & Measurement World Staff - July 19, 2012
To reduce the approval time and cost of sensitive vehicle electronics, STMicroelectronics offers Transil protection devices that are characterized and certified to the automotive industry’s ISO 7637 and ISO 10605 specifications for electrical transients and ESD strikes. Transient voltage suppressors in the SM4TY–SM30TY series are also qualified to the AEC-Q101 automotive reliability test standard for discrete semiconductors and have a full AGAC (Automotive-Grade Approval Certificate).
The clamping devices are housed in miniature surface-mounted power packages that occupy from 12.8 mm2 to 46 mm2 of pc board space and are capable of handling 400 W to 3000 W of power contained in the pulses and ESD transients present in vehicle wiring. Devices in the series include:
- SM4TY: 400W, 2.55x5.05-mm SMA package;
- SMA6TY: 600 W, 2.55x5.05-mm SMA package;
- SM6TY: 600 W, 3.60x5.35-mm SMB package;
- SM15TY: 1500 W, 5.90x7.95-mm SMC package; and
- SM30TY: 3000 W, 5.90x7.95-mm SMC package.
Prices for the AGAC protection devices range from $0.118 to $0.528 for unidirectional types and from $0.129 to $0.558 for bidirectional types.
