# SMAJ30A

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

SMAJ30A 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 terminal, marked by the color band on the unidirectional SMAJ30A (VRWM 30 V, VBR 33.3 V min at 1 mA, VC 48.4 V at Ipp 8.3 A). |
| 2 | A | passive | Anode terminal, the end opposite the color band on the unidirectional SMAJ30A; the transient current path is cathode to anode in reverse breakdown. |

## CAD (KiCad official)

- Symbol: `SMAJ30A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
- 3D model files: `smaj30a-etched.step` / `smaj30a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smaj30a.step` / `smaj30a.glb` are the bare package body.
