Overview

The KY2312 is a MOSFET made by KY in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.25W 105pF 20V 30mΩ@2.5V 55pF 5A 865pF 900mV N-Channel SOT-23 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 6,105 are in stock at JLCPCB (part C3029280).

Questions

Is there a KiCad symbol and footprint for the KY2312?

Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D 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 KY2312?

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

Where is the KY2312 datasheet?

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

Where can I order the KY2312?

JLCPCB lists it as part C3029280, with 6,105 in stock; the sellers' links on this page open their listings.

What can replace the KY2312?

Parts like it in the library: the AO3400A by Alpha & Omega Semiconductor, the AO3400A by UMW, the AO3400 by Guangdong Hottech and the AO3400 by FOSAN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
