Overview

The FMMT458TA is a bipolar made by Diodes Incorporated in a SOT-23 package with 3 pins. -55℃~+150℃ 1 NPN 100 100nA 200mV 225mA 400V 500mW 50MHz 7V NPN SOT-23 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (dk_Transistors-Bipolar-BJT-Single:FMMT458TA, from Digikey) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 21,571 are in stock at JLCPCB (part C116737). 4 open-source boards in 2 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the FMMT458TA?

Yes. The symbol is dk_Transistors-Bipolar-BJT-Single:FMMT458TA 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 FMMT458TA?

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

Where is the FMMT458TA datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the FMMT458TA?

JLCPCB lists it as part C116737, with 21,571 in stock; the sellers' links on this page open their listings.

What can replace the FMMT458TA?

Parts like it in the library: the S8050 by YONGYUTAI, the S8550 by YONGYUTAI, the 8550M-D by Foshan Blue Rocket Elec and the SS8550 by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
