Overview

The ZPY18 is a zener Diode made by DIOTEC in a DO-41 package with 2 pins. -50℃~+150℃ 1 Independent 1.3W 16.8V~19.1V 18V 1uA@10V ±5% DO-41 Zener Diodes ROHS.

PCBKit's library has its KiCad symbol (Diode:ZPYxx, from KiCad's library) and its footprint (Diode_THT:D_DO-41_SOD81_P10.16mm_Horizontal, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3731321).

Questions

Is there a KiCad symbol and footprint for the ZPY18?

Yes. The symbol is Diode:ZPYxx and the footprint Diode_THT:D_DO-41_SOD81_P10.16mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ZPY18?

DO-41, with 2 pins. Its footprint is drawn on this page.

Where is the ZPY18 datasheet?

DIOTEC publishes it: the Datasheet link on this page opens it.

Where can I order the ZPY18?

JLCPCB lists it as part C3731321, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ZPY18?

Parts like it in the library: the 1N4746A by LGE, the 1N4746APF-M by STMicroelectronics, the 1N4746ATR by onsemi and the 1N4746A-TR by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
