Diodes Incorporated has introduced 84 new automotive-qualified Transient Voltage Suppression (TVS) diodes packaged in a choice of SMA, SMB or SMC packages.
These devices are intended for use in a wide range of automotive applications, in which they protect sensitive circuits such as Electronic Control Units (ECUs) from powerline transients generated by inductive switching at the alternator or at an electric motor.
The reverse stand-off voltage values available in the new TVS products range from 14V to 36V. They are supplied as both unidirectional and bidirectional devices. Power dissipation ratings, tested for 10/1,000μs pulses, are 400W for the SMA package, 600W for the SMB and 3,000W for the SMC.
All parts conform to the specifications of the ISO 7637-2 automotive standard for load dumps, pulses 1, 2a, 2b and 3. The diodes are also compatible with the ISO 10605 ESD standard.
