# BZX84C5V1-E3-08

**Vishay Intertech** · Zener Diodes · SOT-23

BZX84C5V1-E3-08 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; in the BZX84C5V1 the Zener voltage is 4.85 V min, 5.1 V nom and 5.36 V max at IZT1 = 5 mA. |
| 2 | NC | unconnected | Not connected internally; pin 2 is drawn with no connection in the single-diode circuit symbol. |
| 3 | K | passive | Cathode of the single Zener diode; the datasheet gives a maximum power dissipation of 500 mW (RthJL = 250 K/W) and a junction temperature of 150 °C. |
