Surge protection for general-purpose lines
The 1.5SMC15CA-E3/9AT: It clamps transients at 21.2 V maximum when the surge current reaches 70.8 A, protecting downstream circuitry from overvoltage events on power or signal rails. The single bidirectional channel means it handles both positive and negative transients on the same line — useful for AC-coupled or bipolar signal paths.
Package and board-fit for the DO-214AB footprint
Housed in the DO-214AB (SMC) package, the device is surface-mount and fits the standard SMCJ footprint. Operating temperature spans -65°C to 150°C (junction), covering cold-start industrial gear and under-hood automotive environments. The wide range means no derating concern for most general-purpose applications, though the 1500 W rating assumes a 25°C ambient — derate linearly above that per the datasheet curve.
