Overview

The MMBTA42 is a bipolar Transistors BJT made by HT in a SOT-23 package with 3 pins. 1 NPN 100 200mV 250nA 300V 300mA 350mW 50MHz 5V NPN SOT-23 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:MMBTA42, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 4 are in stock at JLCPCB (part C692837).

Questions

Is there a KiCad symbol and footprint for the MMBTA42?

Yes. The symbol is Transistor_BJT:MMBTA42 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 MMBTA42?

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

Where is the MMBTA42 datasheet?

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

Where can I order the MMBTA42?

JLCPCB lists it as part C692837, with 4 in stock; the sellers' links on this page open their listings.

What can replace the MMBTA42?

Parts like it in the library: the PBSS4140T by Nexperia, the FMMT591-TP by Micro Commercial Components, the NSS20201L by onsemi and the SS8550 by powersilicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
