MMSZ5V6CW from Shenzhen Jinkaisheng Elec, 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 band; the zener regulates at VZ 5.32 V min / 5.6 V nom / 5.88 V max at IZT = 5 mA when reverse biased. |
| 2 | A | passive | Anode; forward voltage is 900 mV maximum at IF = 10 mA, and power dissipation is limited to 500 mW. |
