Product details

The 1.5SMC36CAHE3/9AT: Reverse standoff voltage is 30.8V typical, with a minimum breakdown voltage of 34.2V.

Automotive-grade transient protection

AEC-Q101 qualification means this part has passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. Surface-mount assembly keeps the thermal path short: the large copper tab on the bottom conducts heat into the board's copper plane, which is the primary heatsink during a transient event.

The base product number 1.5SMC36 covers the full family (unidirectional, bidirectional, different voltage grades). If a design needs a unidirectional version or a different standoff voltage, the same DO-214AB footprint applies — the pad layout does not change across the 1.5SMC range.

Frequently asked questions

What is the closest pin-compatible alternative in the same family?

Within the 1.5SMC36 base number, the unidirectional version (1.5SMC36AHE3) shares the same DO-214AB package and voltage ratings but protects only one polarity. For a bidirectional replacement with identical electrical specs, the non-automotive grade 1.5SMC36CA (without the HE3 suffix) is pin-compatible but lacks AEC-Q101 qualification.
