Vishay Intertech · Zener Diodes · SOD-80
TLZ12B-GS08 from Vishay Intertech, in a SOD-80. 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 of the Zener diode, marked by the cathode identification band on the MiniMELF body; the datasheet lists VZ 2.4 to 56 V nominal for the series (TLZ12B: 11.44 to 12.03 V at IZT1 = 10 mA). |
| 2 | A | passive | Anode of the Zener diode; the datasheet gives Ptot of 500 mW and a maximum forward voltage of 1.5 V at IF = 200 mA. |
