ZMY9V1-GS08

Vishay Intertech · Zener Diodes · DO-213AB

ZMY9V1-GS08 from Vishay Intertech, 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 terminal, identified by the cathode marking band on the MELF DO-213AB body; the Zener (ZMY9V1: 9.1 V nominal, 8.5 to 9.6 V at 50 mA) voltage is positive at this terminal in reverse breakdown.
2 A passive Anode terminal at the end of the MELF DO-213AB body opposite the cathode marking; maximum power dissipation is 1000 mW provided the electrodes are kept at ambient temperature.
