The 1.5SMC22CAHR7G: Reverse standoff voltage is 18.8 V, with a breakdown range starting at 20.9 V and clamping at 30.6 V — this defines the protection window for a nominal 18 V or 24 V automotive rail. AEC-Q101 qualification and a junction temperature range of -55°C to +150°C make it suitable for under-hood or high-vibration environments where commercial-grade parts risk parametric drift.
AEC-Q101 screening and thermal envelope
AEC-Q101 certification includes wafer-level reliability testing, high-temperature operating life, and preconditioning for automotive stress — not just a datasheet claim but a screened lot pedigree.
Package and board integration — DO-214AB (SMC)
Tape-and-reel packaging supports automated pick-and-place; the single bidirectional channel means no polarity marking to verify during assembly.
