# BZX84B22Q-7-F

**Diodes Incorporated** · Zener Diodes · SOT-23-3

BZX84B22Q-7-F from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the Zener diode. Under reverse bias this pin sits ~22 V above the Anode at the rated test current (IZT = 5 mA); marked side / cathode band convention per Diodes Inc SOT-23 outline. |
| 2 | NC | unconnected | No internal connection on the SOT-23 package. Leave floating or tie to Anode for board-level convenience; carries no die connection in the BZX84 SOT-23 single-die zener. |
| 3 | A | passive | Anode of the Zener diode. Reference/return terminal for both the Zener reverse-breakdown current path (IZT = 5 mA nominal, IZK = 1 mA knee) and the forward-conduction path (VF = 0.9 V @ IF = 10 mA). |
