Overview

The BAV21 is a switching Diode made by DIOTEC in a DO-35 package with 2 pins.

PCBKit's library has its KiCad symbol (Diode:BAV21, from KiCad's library) and its footprint (Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C17225679). 9 open-source boards in 9 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the BAV21?

Yes. The symbol is Diode:BAV21 and the footprint Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BAV21?

DO-35, with 2 pins. Its footprint is drawn on this page.

Where is the BAV21 datasheet?

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

Where can I order the BAV21?

JLCPCB lists it as part C17225679, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BAV21?

Parts like it in the library: the BAV21W by Shandong Jingdao Microelectronics, the BAV21WS by MDD, the BAV20W by Shandong Jingdao Microelectronics and the BAV21W by Wild Goose. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BAV21?

9 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
