ZM4733A-GS08

Vishay Intertech · Zener Diodes · DO-213AB

ZM4733A-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, the end marked by the cathode identification band; the Zener reference voltage (VZ nom. 5.1 V at IZT 49 mA for ZM4733A) appears with this end positive in reverse breakdown.
2 A passive Anode, the unmarked end of the MELF body; the gap between plug and glass can be on either the cathode or anode side.
