Key ratings and what they mean for circuit protection
The 1.5SMC12CA: The 10.2 V reverse standoff voltage means it starts clamping above that level, protecting downstream circuitry from transients up to 16.7 V clamping at 91 A peak pulse current. The single bidirectional channel handles symmetrical clamping — useful for AC signal lines or differential pairs where polarity is not fixed.
Housed in a DO-214AB (SMC) surface-mount package, also designated as supplier device package SMCJ. The footprint is standard for this power class — the same pad layout used by other 1500 W TVS diodes in SMC packages, easing second-sourcing.
Sourcing and compliance
Sourced to order against your BOM quantity through independent distribution. Littelfuse provides standard compliance documentation including RoHS and REACH declarations; UL recognition and IEC qualification data are available per the manufacturer's datasheet.
