Product details

500 W bidirectional TVS for 15 V rails

The SA15CA-T: The DO-204AC (DO-15) axial-lead through-hole package allows straightforward board-level replacement and good thermal dissipation into the PCB traces or heatsink pads.

Obsolete — sourcing through independent channels

Diodes Incorporated has marked the SA15CA-T as obsolete. For a 15 V bidirectional TVS in a DO-15 package, a parametric search across the same power class (500 W) and standoff voltage will yield active alternatives from Diodes and other brands, but board-level fit (lead form, body length) must be verified against the existing footprint.

Frequently asked questions

How can I order the SA15CA-T or check current availability?

The SA15CA-T is obsolete but can be sourced through independent distribution.

Is the SA15CA-T a bidirectional or unidirectional device?

It is a bidirectional TVS with one channel, meaning it clamps transients of either polarity on a single line.
