SMB5388A from ZHIDE, in a SMB. 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, identified by the color band on the package; the 200 V nominal Zener (190-210 V at IZT = 5 mA) is stabilized with this terminal positive relative to the anode. |
| 2 | A | passive | Anode terminal of the Zener diode; maximum forward voltage is 1.2 V at IF = 200 mA. |
