BZX84C15-Y4
SY(顺烨) · IC · SOT-23
BZX84C15-Y4 from SY(顺烨), 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 | K | passive | Zener diode cathode; BZX84C15 has a nominal Zener voltage of 15V (13.8V to 15.6V) at IZT = 5mA. |
| 2 | NC | unconnected | No internal connection; the package drawing shows pin 2 not connected to the diode. |
| 3 | A | passive | Zener diode anode; device power dissipation is limited to 350mW. |
