ZMY20

(DIOTEC) · Zener Diodes · DO-213AB

ZMY20 from (DIOTEC), in a DO-213AB. 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 of the Zener diode, marked by the white cathode mark on the plastic MELF body, connected to the positive side in reverse (Zener) operation.
2 A passive Anode of the Zener diode (opposite MELF end terminal from the cathode mark) for the 18.8 V to 21.2 V ZMY20 at IZtest = 25 mA.
