Overview

The BAV21W is a switching Diode made by SMC in a SOD-123 package with 2 pins. -65℃~+150℃@(Tj) 1V@100mA 200V 200mA 200nA@200V 50ns Independent SOD-123 Switching Diodes ROHS.

PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_SOD-123, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3313002).

Questions

Is there a KiCad symbol and footprint for the BAV21W?

Yes. The symbol is Device:D and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BAV21W?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the BAV21W datasheet?

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

Where can I order the BAV21W?

JLCPCB lists it as part C3313002, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BAV21W?

Parts like it in the library: the 1N4148W by STMicroelectronics, the 1N4148W by hongjiacheng, the 1N4148W by Jiangsu Changjing Electronics Technology (CJ) and the 1N4148W by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
