The 1.5SMC36CH: The 32.4V minimum breakdown voltage and 52V maximum clamping at 30A peak pulse current define the protection window — a 24V or 28V rail sees clamping well below the 52V ceiling, so downstream components rated for 60V have comfortable margin.
Automotive qualification and temperature range
AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. The single bidirectional channel clamps both polarities in one package, saving board space compared to two unidirectional diodes in anti-series.
DO-214AB (SMC) surface-mount package with tape-and-reel delivery suits automated assembly. The SMC footprint is larger than the SMA/SMB siblings, which helps thermal dissipation during the 1500W pulse — the copper pad area under the cathode tab directly sets the transient thermal impedance.
