BZX84B5V1Q-7-F
Diodes Incorporated · Zener Diodes · SOT-23-3
BZX84B5V1Q-7-F from Diodes Incorporated, in a SOT-23-3. 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 on the bottom-left lead of the device schematic. |
| 2 | NC | unconnected | No internal connection; the device schematic shows this lead with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, shown on the single top lead of the device schematic; it is the positive terminal in reverse-breakdown operation. |
