Product details

TVS diode selection — 1500 W bidirectional clamp

The 1.5SMC18CA-E3/9AT: It is built for general-purpose circuit protection in surface-mount designs. This means the diode starts conducting at around 17 V and limits transients to under 25.2 V — suitable for protecting 12 V and 15 V rails against surges.

Package and board-fit

Supplied in Tape & Reel, ready for automated pick-and-place assembly. The single bidirectional channel covers both positive and negative transients, so no orientation concern on the PCB.

Sourcing and lifecycle status

Sourced through independent distribution channels. No stock-holding claim — quoted to order per RFQ.

Frequently asked questions

What is the peak pulse power rating of 1.5SMC18CA-/9AT?

This is the industry-standard rating for this package size — enough to handle most secondary surge events on 12 V and 15 V power rails.
