What are the primary applications for the AO3402?

It is primarily used for load switching and PWM (Pulse Width Modulation) applications in consumer and industrial electronics.

What should engineers review before using the AO3402?

Engineers should review the thermal resistance (RθJA = 357°C/W) to ensure the device stays within safe operating temperatures under load.

What are the key specifications of the AO3402?

Key specs include a 30V VDS, 4A continuous drain current, and a typical RDS(on) of 55mΩ at VGS=10V.

What should sourcing teams check before buying AO3402?

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

What is the pinout of AO3402?

Use the AO3402 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about AO3402 pinout to locate pins, power rails, and interface signals before layout.
