BZX84-B15

Nexperia · Zener Diodes · SOT-23(TO-236AB)

BZX84-B15 from Nexperia, in a SOT-23(TO-236AB). 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 voltage regulator diode.
2 n.c. unconnected Not connected.
3 K passive Cathode of the voltage regulator diode; the cathode tab is the soldering point for thermal resistance Rth(j-sp) of 330 K/W max.
