BZX84B13

YFW · Zener Diodes · SOT-23

BZX84B13 from YFW, 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 ANODE passive Anode of the Zener diode; the datasheet gives no lead-specific limits, so the absolute maximum ratings apply (power dissipation 350 mW, junction and storage temperature -65 to +150 °C).
2 NC unconnected Lead 2 is numbered in the SOT-23 outline drawing, but the datasheet assigns it no function and gives no electrical limits for it.
3 CATHODE passive Cathode of the Zener diode; for the BZX84B13 the nominal Zener voltage is 13 V, with 12.7 V minimum and 13.3 V maximum at IZT = 5 mA.
