The 1.5SMC56CAH: The SMC footprint is larger than the SMA/SMB siblings, providing a wider copper pad area under the terminals for thermal dissipation during the pulse event — critical for maintaining the 1500W rating without exceeding the junction temperature limit.
The device type is Zener (bidirectional TVS), and the grade is Automotive, backed by AEC-Q101 qualification.
