What are the key electrical specifications?

It features a 20V drain-source voltage, 3A continuous drain current, and typical RDS(ON) of 30mΩ at 4.5V gate drive.

What are the primary applications?

It is ideal for load switching, battery management, and general power control in space-constrained designs.

What should be considered for thermal design?

The SOT-23 package has limited heat dissipation. Ensure the PCB layout provides adequate copper area for heat sinking to maintain junction temperature within limits.

What should sourcing teams check before buying SI2302?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: low; readiness: easy.

What is the pinout of SI2302?

Use the SI2302 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SI2302 pinout to locate pins, power rails, and interface signals before layout.
