The 1.5SMC56CAHE3_A/H: It is qualified to AEC-Q101, the automotive-grade discrete semiconductor reliability standard, and operates across a junction temperature range of -65°C to 150°C.
The package footprint is compatible with common SMC pad layouts, and the bidirectional construction means a single device clamps both polarities without series stacking.
Automotive-grade transient suppression
With AEC-Q101 qualification, this TVS is screened for the thermal and reliability demands of under-hood or chassis-mounted electronics, including 125°C ambient soak and 150°C junction peaks.
