**Yangzhou Yangjie Elec Tech** · Zener Diodes · SOT-23(TO-236)

BZX84B7V5 from Yangzhou Yangjie Elec Tech, in a SOT-23(TO-236). 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, connected to the diode's left side in the datasheet symbol; the Zener voltage of BZX84B7V5 is 7.5V typ (7.35V to 7.65V) at IZT=5mA. |
| 2 | NC | unconnected | No internal connection; the datasheet symbol shows pin 2 with no connection to the diode. |
| 3 | K | passive | Cathode of the Zener diode, connected to the diode's right side in the datasheet symbol; it goes positive relative to pin 1 in Zener breakdown. |
