Taiwan Semiconductor · Zener Diodes · SOT-23
BZX84C7V5 RFG from Taiwan Semiconductor, 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 | A | passive | Zener diode terminal on the lower-left lead in the polarity diagram, joined internally to pin 3 through the diode; the datasheet gives no further function for it. |
| 2 | NC | unconnected | Lower-right lead, drawn with no internal connection in the polarity diagram. |
| 3 | K | passive | Top lead of the polarity diagram, which is the other terminal of the single Zener diode (7.5 V nominal at 5 mA for BZX84C7V5). |
