# SMAZ7V5-MS

**MSKSEMI** · Zener Diodes · SMA

SMAZ7V5-MS from MSKSEMI, 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 colour band; the Zener (5.1 to 39 V series) conducts in reverse when this pin is positive of the anode, and the SMAZ7V5-MS has a nominal VZ of 7.5 V (7.13 to 7.88 V) at IZT = 100 mA. |
| 2 | A | passive | Anode, the end without the colour band; the Zener is forward biased when this pin is positive of the cathode, with a maximum VF of 1.2 V at IF = 200 mA. |

## CAD (KiCad official)

- Symbol: `SMAZ7V5-MS`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `smaz7v5-ms-etched.step` / `smaz7v5-ms-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smaz7v5-ms.step` / `smaz7v5-ms.glb` are the bare package body.
