# SMA5914A

**ZHIDE** · Zener Diodes · DO-214AC(SMA)

SMA5914A from ZHIDE, 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 by the color band; the Zener voltage of SMA5914A is 3.6 V nominal (3.42 to 3.78 V) at IZT = 104.2 mA, with 1.5 W power dissipation at TL = 75 °C. |
| 2 | A | passive | Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA. |
