Product details

Device identity and key parametrics

The SMAJ28CA-13-F: The single bidirectional channel means the device protects against both positive and negative transients with one component, simplifying PCB layout for symmetrical rail protection.

Housed in a DO-214AC (SMA) surface-mount package, the SMAJ28CA-13-F occupies a standard footprint with a low profile suitable for dense PCB layouts. Supplied in Tape & Reel (TR) and Cut Tape (CT) options, it integrates directly into pick-and-place assembly without process changes.
