What are the key electrical ratings?

It features a 4A hold current, 8A trip current, 15V maximum operating voltage, and 40A maximum fault current.

What should be considered during design?

Ensure the circuit operating temperature is within the -40°C to +85°C range and account for thermal derating if the ambient temperature exceeds 23°C.

Is this device suitable for continuous fault conditions?

No, it is intended for sporadic, accidental overcurrent protection and should not be used in applications with constant or repeated fault conditions.

What is the pinout of SMD2920P400TF?

Use the SMD2920P400TF datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SMD2920P400TF pinout to locate pins, power rails, and interface signals before layout.
