# SMA5929A

**Yangzhou Yangjie Elec Tech** · Zener Diodes · SMA(DO-214AC)

SMA5929A from Yangzhou Yangjie Elec Tech, in a SMA(DO-214AC). 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 cathode line on the body; the Zener voltage is nominally 15.0 V (14.25 V to 15.75 V) at IZT = 25.0 mA for the SMA5929A. |
| 2 | A | passive | Anode terminal at the end opposite the cathode line; the maximum DC power dissipation is 1.5 W at TL = 75 °C and the maximum forward voltage is 1.5 V at IF = 200 mA. |

## CAD (KiCad official)

- Symbol: `SMA5929A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `sma5929a-etched.step` / `sma5929a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sma5929a.step` / `sma5929a.glb` are the bare package body.
