BZX85B10

LGE · Zener Diodes · DO-41

BZX85B10 from LGE, in a DO-41. 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 by the color band on the DO-41 axial package; the Zener voltage of the BZX85B10 is 10 V nominal at IZT = 25 mA (±2.0%).
2 A passive Anode, the axial lead opposite the color band; maximum DC power dissipation is 1.3 W at TL = 50 °C and maximum forward voltage is 1.2 V at IF = 200 mA.
