Product details

1.5kW pulse rating and clamping performance

The 1.5SMC12A: With a 10.2V reverse standoff voltage and a minimum breakdown of 11.4V, the diode stays transparent during normal 12V bus operation and begins conducting only when the line exceeds the threshold. The clamping voltage is 16.7V at the rated 91A peak pulse current — low enough to keep a 12V-rated load within its abs-max.

Housed in a DO-214AB (SMC) surface-mount package, the 1.5SMC12A uses the standard JEDEC footprint shared with the SMCJ family — the supplier device code is DO-214AB (SMCJ). Available in Tape & Reel (TR) or Cut Tape (CT) options, the part is ready for pick-and-place assembly. No power line protection is claimed — this is a signal- or secondary-side rail clamp, not a primary mains suppressor.

Frequently asked questions

How do I get current pricing and availability for 1.5SMC12A?

We source the 1.5SMC12A through authorized and independent distribution channels. Submit an RFQ with your target quantity and date-code preference; pricing and lead time are confirmed at quote time. No stock-holding claim is made — availability is verified per inquiry.

What is 1.5SMC12A's listed type (Zener) on this Circuit Protection line?

The device type is Zener — a single-junction avalanche diode designed for unidirectional transient suppression. It clamps positive overvoltage transients relative to ground; for bidirectional protection, the suffix changes to 'CA' (e.g., 1.5SMC12CA).
