BZX55C47

LGE · Zener Diodes · DO-35

BZX55C47 from LGE, in a DO-35. 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, the end marked by the polarity band; for the BZX55C47 the zener voltage is 44 to 50 V at IZT = 2.5 mA.
2 A passive Anode, the end without the polarity band; maximum forward voltage is 1.0 V at IF = 100 mA with 500 mW power dissipation.
