Overview

The AP4438 is a MOSFET made by ALLPOWER in a SOT-89 package with 3 pins. -55℃~+150℃ 1 N-channel 1.28nF 105pF 11.5mΩ@10V 11.8A 125pF 16.8nC 2.5W 30V 3V N-Channel SOT-89 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2D_3S, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-89-3, from KiCad's library), ready for a KiCad board. 4,550 are in stock at JLCPCB (part C353072).

Questions

Is there a KiCad symbol and footprint for the AP4438?

Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AP4438?

SOT-89, with 3 pins. Its footprint is drawn on this page.

Where is the AP4438 datasheet?

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

Where can I order the AP4438?

JLCPCB lists it as part C353072, with 4,550 in stock; the sellers' links on this page open their listings.

What can replace the AP4438?

Parts like it in the library: the TDM3426B by Techcode Semicon, the SL9968 by Slkor, the KNS8104A by KIA Semicon Tech and the TM15N10SI by Tritech-MOS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
