# TPSMAJ16CA

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

TPSMAJ16CA 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 1 (TPSMAJ16CA); the part has no cathode band and is symmetric, so either terminal can connect to the protected line, with a 16.0 V reverse stand-off voltage. |
| 2 | A2 | passive | Bi-directional TVS terminal 2 (TPSMAJ16CA); the part has no cathode band and is symmetric, so either terminal can connect to the protected line, with a 16.0 V reverse stand-off voltage. |

## CAD (KiCad official)

- Symbol: `TPSMAJ16CA`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
- 3D model files: `tpsmaj16ca-etched.step` / `tpsmaj16ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpsmaj16ca.step` / `tpsmaj16ca.glb` are the bare package body.
