Overview

The FDC645N is a MOSFET made by onsemi in a TSOT-23-6 package with 6 pins. -55℃~+150℃ 1 N-channel 1.46nF 1.6W 21nC@4.5V 2V 30V 30mΩ@4.5V 5.5A 96pF N-Channel TSOT-23-6 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1D_2D_3G_4S_5D_6D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:TSOT-23-6, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C241775). 2 open-source boards in 2 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the FDC645N?

Yes. The symbol is Pinmap_Generic:Q_NMOS_1D_2D_3G_4S_5D_6D and the footprint Package_TO_SOT_SMD:TSOT-23-6, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FDC645N?

TSOT-23-6, with 6 pins. Its footprint is drawn on this page.

Where is the FDC645N datasheet?

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

Where can I order the FDC645N?

JLCPCB lists it as part C241775, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FDC645N?

Parts like it in the library: the AP3003 by ALLPOWER, the DMG6402LVT by Diodes Incorporated, the FDC655BN by TECH PUBLIC and the STT6N3LLH6 by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the FDC645N?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
