Overview

The S8550 is a bipolar Transistors BJT made by HT in a SOT-23 package with 3 pins. SOT-23 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:S8550, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 1,459 are in stock at JLCPCB (part C746282).

Questions

Is there a KiCad symbol and footprint for the S8550?

Yes. The symbol is Transistor_BJT:S8550 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the S8550?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the S8550 datasheet?

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

Where can I order the S8550?

JLCPCB lists it as part C746282, with 1,459 in stock; the sellers' links on this page open their listings.

What can replace the S8550?

Parts like it in the library: the MMS9013-H-TP by Micro Commercial Components, the MMS9012-H-TP by Micro Commercial Components, the S9012G by Galaxy Microelectronics and the SS8050 Y1 200-350 by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
