Overview

The IRF644 is a MOSFET made by Texas Instruments in a TO-220AB package with 3 pins. -55℃~+150℃ 1 N-channel 1.3nF 125W 14A 250V 280mΩ@10V 320pF 4V 59nC@10V 69pF N-Channel TO-220AB MOSFETs.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2D_3S, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-220-3_L10.2-W4.5-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C3280737). 4 open-source boards in 4 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the IRF644?

Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-220-3_L10.2-W4.5-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the IRF644?

TO-220AB, with 3 pins. Its footprint is drawn on this page.

Where is the IRF644 datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the IRF644?

JLCPCB lists it as part C3280737, with 0 in stock; the sellers' links on this page open their listings.

What can replace the IRF644?

Parts like it in the library: the TK5A50D(STA4,X,M) by Toshiba, the DOP85P06 by DOINGTER, the MPG120N06 by Minos and the STP110N7F6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the IRF644?

4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
