TLZ3V3B-GS08 from VISHAY GENERAL SEMICONDUCTOR - DIODES DIVISION, 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, the end marked with the cathode identification band; the Zener reverse-breakdown terminal, VZ 3.32 to 3.53 V at IZT1 = 20 mA for TLZ3V3B. |
| 2 | A | passive | Anode, the end opposite the cathode band; Zener current IZ is limited to Ptot/VZ with Ptot 500 mW. |
