BZX84B5V1Q
YANGJIE(扬杰) · IC · SOT-23
BZX84B5V1Q from YANGJIE(扬杰), 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 | Anode of the Zener diode (forward conduction at VF 0.9 V max at IF=10 mA); the BZX84B5V1Q reverse Zener voltage is 5.0 to 5.2 V (5.1 V typ) at IZT=5 mA. |
| 2 | NC | unconnected | Not connected internally; pin 2 has no connection to the diode in the package schematic. |
| 3 | K | passive | Cathode of the Zener diode; goes positive relative to the anode in regulation, with power dissipation limited to 350 mW and IZM = PD/VZ. |
