Automotive-grade TVS in a DO-214AA SMB package
Protection window: standoff, breakdown, and clamping
The reverse standoff voltage is 18.8 V, meaning the TVS does not conduct leakage current below this rail voltage. The minimum breakdown voltage is 20.9 V, where the device starts to avalanche. Under a peak pulse current of 102 A (8/20 µs waveform), the clamping voltage is limited to 30.6 V — this is the maximum voltage the downstream circuitry sees during the transient event. With a peak pulse power rating of 600 W (10/1000 µs waveform), this part handles the energy from typical load-dump and inductive-load switching transients on 12 V and 24 V automotive power rails.
Lifecycle and compliance for BOM planning
It is AEC-Q101 qualified, which means the PPAP documentation and part-per-million defect rate controls are available for automotive OEM submissions. The base product number is SM6T22, and the 'Y' suffix denotes the automotive-grade qualification.
