onsemi · Zener Diodes · SOT-23
BZX84C4V3LT1G from onsemi, 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 | Anode | passive | Anode terminal of the Zener diode; the datasheet gives no pin-specific voltage or current limits, only the device-level Zener ratings. |
| 2 | NC | unconnected | No connection; the datasheet specifies this lead as not connected internally. |
| 3 | Cathode | passive | Cathode terminal, identified by the polarity band on the package; for BZX84C4V3LT1G the datasheet gives a nominal Zener voltage VZ of 4.3 V (min 4.0 V, max 4.6 V at IZT1 = 5 mA). |
