TVS diode with 1500 W peak pulse rating and 10 V standoff
The SMCJ10A-13-F: The reverse standoff voltage is 10 V, so the diode stays out of circuit below that level.
Package, temperature range, and board integration
Housed in the DO-214AB (SMC) package, this is a surface-mount part with a standard footprint for TVS diodes in this power class. The unidirectional configuration means it clamps only one polarity; for bidirectional protection on an AC-coupled line, a pair back-to-back or a bidirectional variant would be needed.
