Breakdown and clamping thresholds for rail protection
The 1.5SMC13CA-M3/57T: The 18.2 V maximum clamping voltage at Ipp ensures downstream components rated for 20 V or higher see a safe voltage during a surge event — a critical parameter for protecting sensitive ICs on a 12 V bus. Operating temperature spans -65°C to 150°C (junction), covering the full industrial and automotive underhood range without derating concerns at the board level.
DO-214AB footprint and surface-mount assembly
Housed in a DO-214AB (SMC) package with a supplier device package designation of DO-214AB (SMCJ), this TVS uses a standard surface-mount footprint shared across the 1.5SMC series — the same pad layout works for any voltage variant in the family. Supplied on Tape & Reel (TR), it is compatible with high-volume pick-and-place assembly lines without a process change.
