BZX84B5V1-HE3-08

Vishay Intertech · Zener Diodes · SOT-23

BZX84B5V1-HE3-08 from Vishay Intertech, 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 single Zener diode (5.1 V nominal, 2 % tolerance, 5.00 to 5.20 V at IZT1 = 5 mA for the BZX84B5V1).
2 NC unconnected Not connected internally; the circuit symbol shows no connection to the diode on this pin (single-diode circuit configuration).
3 K passive Cathode of the single Zener diode (5.1 V nominal, 2 % tolerance, 5.00 to 5.20 V at IZT1 = 5 mA for the BZX84B5V1).
