YONGYUTAI · Zener Diodes · SOD-123
MM1Z27V from YONGYUTAI, in a SOD-123. 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 (reverse breakdown) voltage of the MM1Z27V is 25.1 V min to 28.9 V max at Izt = 2 mA. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.9 V at IF = 10 mA and power dissipation is 500 mW. |
