TPSMAJ14CA

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · DO-214AC(SMA)

TPSMAJ14CA from TECH PUBLIC, in a DO-214AC(SMA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Bi-directional TVS terminal (no polarity, no cathode band on the CA type) with 14.0 V reverse stand-off, 15.6 V to 17.2 V breakdown at 1 mA, and 23.2 V maximum clamping at 17.2 A peak pulse current.
2 A2 passive Second bi-directional TVS terminal, interchangeable with the first, with 14.0 V reverse stand-off, 1 uA maximum reverse leakage, and 400 W minimum peak pulse power on a 10/1000 us waveform.
