# SMAJ16A

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

SMAJ16A from GOODWORK, 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 | K | passive | Cathode, the end marked with the color band on the unidirectional SMAJ16A; reverse stand-off voltage 16 V, breakdown 17.8 V min at 1 mA, clamping 26.0 V at 15.3 A. |
| 2 | A | passive | Anode, the end without the color band on the unidirectional SMAJ16A; conducts in the forward direction with the TVS clamping positive surges at the cathode. |

## CAD (KiCad official)

- Symbol: `SMAJ16A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
- 3D model files: `smaj16a-etched.step` / `smaj16a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smaj16a.step` / `smaj16a.glb` are the bare package body.
