BZX84B5V1-HE3-08 from Vishay Intertech, in a SOT-23. 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 | A | passive | Anode of the single Zener diode (5.1 V nominal, 2 % tolerance, 5.00 to 5.20 V at IZT1 = 5 mA for the BZX84B5V1). |
| 2 | NC | unconnected | Not connected internally; the circuit symbol shows no connection to the diode on this pin (single-diode circuit configuration). |
| 3 | K | passive | Cathode of the single Zener diode (5.1 V nominal, 2 % tolerance, 5.00 to 5.20 V at IZT1 = 5 mA for the BZX84B5V1). |
