BZT52B10-E3-08

Vishay Intertech · Zener Diodes · SOD-123

BZT52B10-E3-08 from Vishay Intertech, in a SOD-123. 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 Cathode (marked with the cathode bar); positive terminal of the Zener diode, which goes positive relative to the anode in reverse Zener operation (BZT52B10: VZ 9.80 to 10.20 V at IZT1 = 5 mA).
2 A passive Anode of the Zener diode; Ptot is 500 mW (RthJL = 250 K/W) and 300 mW on FR-4 board with recommended footprint.
