Product details

Breakdown and clamping — where protection starts

The SMAJ17A-13-F: The reverse standoff voltage is 17 V; the device remains non-conductive below that. This 10 V window between standoff and clamp means the TVS activates before the protected IC's abs-max rating is reached on a 24 V tolerant input.

DO-214AC SMA — board-fit and sourcing

Packaged in DO-214AC (SMA) with a surface-mount footprint. The base product number is SMAJ17, so the -13-F suffix denotes the reel and lead-free finish.
