What are the key specifications of the ASMD1812-200?

It features a 2A hold current, 4A trip current, 8V maximum operating voltage, and a maximum fault current of 100A.

What should engineers review before using the ASMD1812-200?

Engineers should review the thermal derating chart, as the hold current decreases at higher ambient temperatures, and ensure the circuit voltage does not exceed the 8V rating.

What are the common applications for this device?

It is commonly used in USB hubs, motherboard protection, HDMI ports, game console ports, and general electronic circuit protection.

What is the pinout of ASMD1812-200?

Use the ASMD1812-200 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about ASMD1812-200 pinout to locate pins, power rails, and interface signals before layout.
