Product details

500W bidirectional Zener clamp – DO-15 axial

The SA15CA: It clamps transients at 24.4V max, handling 20.6A peak pulse current. The single bidirectional channel means it protects both positive and negative surges — useful on AC signal lines or bipolar DC rails where polarity isn't fixed.

onsemi lists the SA15CA as Obsolete. A board-level replacement would require a different order code; no pin-compatible drop-in is documented.

Through-hole mounting – DO-15 axial footprint

The SA15CA ships in a DO-204AC (DO-15) axial-lead package. Through-hole mounting means it survives reflow without MSL concerns — the leads solder into plated through-holes, and the body stands off the board.

Frequently asked questions

How can I order the SA15CA or check availability?

The SA15CA is obsolete, so it is sourced through independent surplus channels. No stock-holding claim is made; each lot is verified at order.

Is the SA15CA bidirectional?

Yes. The SA15CA has a single bidirectional channel, clamping both positive and negative transients symmetrically. This suits AC-coupled lines or bipolar supplies where the signal swings above and below ground.
