SMC5378A from ZHIDE, in a SMC. 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; this is the Zener (reverse breakdown) side, with VZ 95.00 V min to 105.00 V max (100 V nominal) for SMC5378A. |
| 2 | A | passive | Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA. |
