BZX84C47LT1G
onsemi · Zener Diodes · SOT-23
BZX84C47LT1G 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's pinout gives 1-Anode and the marking diagram shows Anode at pin 1. |
| 2 | NC | unconnected | No connection; the datasheet lists pin 2 as 'No Connection' in the Style 8 pinout and the electrical characteristics header. |
| 3 | Cathode | passive | Cathode terminal of the Zener diode, indicated on the package by the polarity band (the marking diagram shows Cathode at pin 3). |
