SMB3Z16A from Yangzhou Yangjie Elec Tech, in a SMB(DO-214AA). 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 end, marked by the cathode line; the Zener voltage is 16.0 V typ (15.20 V to 16.80 V) at IZT = 47 mA when this pin is positive relative to the anode. |
| 2 | A | passive | Anode end; forward voltage is 1.5 V max at IF = 200 mA, with DC power dissipation of 3.0 W max at TL = 75 °C. |
