# SMA2Z160A

**ZHIDE** · Zener Diodes · SMA

SMA2Z160A from ZHIDE, in a 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; for a Zener it is positive relative to the anode in regulation (VZ 152.0 V min to 168.0 V max for SMA2Z160A). |
| 2 | A | passive | Anode terminal of the Zener diode; maximum forward voltage is 1.2 V at IF=200 mA. |

## CAD (KiCad official)

- Symbol: `SMA2Z160A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `sma2z160a-etched.step` / `sma2z160a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sma2z160a.step` / `sma2z160a.glb` are the bare package body.
