# BZX84C2V7

**FOSAN** · Zener Diodes · SOT-23

BZX84C2V7 from FOSAN, 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 zener diode, shown connected through the diode to pin 3 in the internal configuration drawing (BZX84C2V7: VZ 2.5-2.9 V at 5 mA, PD 300 mW max). |
| 2 | NC | unconnected | No internal connection; shown as an unconnected dot in the internal configuration drawing. |
| 3 | K | passive | Cathode of the zener diode, shown connected through the diode to pin 1 in the internal configuration drawing (IF 250 mA max, VF 0.9 V max at IF=10 mA). |
