Product details

Gate charge and drive — direct GPIO switching

Maximum gate charge is 6 nC at 4.5 V Vgs, which means a 3.3 V MCU GPIO can switch the FET on and off without a dedicated gate driver IC. The drive voltage range for rated Rds(on) spans 4.5 V to 10 V, so a 5 V logic rail or a 3.3 V rail with a level shifter both work within the ±20 V Vgs max. Input capacitance Ciss is 639 pF at 25 V Vds — a figure that keeps the switching edge rate manageable for EMI-sensitive loads like a sensor rail or a small DC motor.

PowerFlat 2x2 — board area and thermal path

The 6-PowerWDFN package (PowerFlat™ 2x2) occupies a 2x2 mm footprint on the PCB.

Frequently asked questions

Can STL4P3LLH6 be used for high-side switching?

Yes, as a P-Channel MOSFET the STL4P3LLH6 is suited for high-side load switching. The 30 V Vdss and 4 A Id rating cover typical 12 V or 24 V rails, and the 6 nC gate charge at 4.5 V allows direct drive from a logic output with a pull-up resistor to the supply rail.

Is STL4P3LLH6 ROHS compliant?

Yes, the STL4P3LLH6 is listed as ROHS3 Compliant.
