Overview

The LLDB3 is a trigger Diode made by STMicroelectronics in a LL-34 package with 2 pins. -40℃~+125℃ 10uA 28V~36V 2A 2us 50uA 5V LL-34 Trigger Diodes ROHS.

PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_MiniMELF, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C68120).

Questions

Is there a KiCad symbol and footprint for the LLDB3?

Yes. The symbol is Device:D and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LLDB3?

LL-34, with 2 pins. Its footprint is drawn on this page.

Where is the LLDB3 datasheet?

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

Where can I order the LLDB3?

JLCPCB lists it as part C68120, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LLDB3?

Parts like it in the library: the LLDB3 by LGE, the LLDB3 by Slkor, the LLDB3 by YFW and the LLDB4 by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
