# BZX84C13LT1G

**onsemi** · Zener Diodes · SOT-23

BZX84C13LT1G 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 pinout is 1-Anode, 2-No Connection, 3-Cathode, and the cathode is marked by the polarity band on the package. |
| 2 | NC | unconnected | No connection; this pin is not internally connected and the datasheet pinout lists it as No Connection. |
| 3 | CATHODE | passive | Cathode terminal of the Zener diode, identified by the polarity band; the device is specified for Zener breakdown voltage VZ = 12.4 V to 14.1 V at IZT = 5 mA for the BZX84C13LT1G. |
