ZY6.8

(DIOTEC) · Zener Diodes · DO-204AC

ZY6.8 from (DIOTEC), in a DO-204AC. 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 band on the case; connected to the positive side for Zener operation in reverse (VZ 6.4 V to 7.2 V at IZtest = 100 mA for ZY6.8).
2 A passive Anode, the axial lead opposite the banded cathode end; IZmax is 278 mA at TA = 50°C for ZY6.8 and Ptot is 2 W.
