What are the primary applications?

It is widely used in automotive systems, industrial controls, battery packs, and portable consumer electronics.

What happens when the device trips?

When the current exceeds the trip threshold, the device transitions to a high-resistance state, limiting the current flow. It resets automatically once the fault is removed and the device cools down.

What are the key electrical specs?

It features a 2A hold current, 4A trip current, 33V maximum operating voltage, and a 40A maximum fault current rating.

Are there sourcing risks?

The device is currently active and widely available through major distributors, with low supply chain risk.

What is the pinout of BSMD2920-200-33V?
