DOWO · Zener Diodes · SOD-123
MMSZ10 from DOWO, 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 voltage is 10V nominal (9.50V to 10.50V) at the test current, with 500mW maximum power dissipation. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.9V at IF=10mA. |
