What are the key specifications of the SMF30A?

It features a 200W peak pulse power rating, 30V working peak reverse voltage (VRWM), and a maximum clamping voltage of 48.4V.

What is the package type of the SMF30A?

It is housed in a low-profile SOD-123FL package, which is ideal for space-constrained PCB designs.

What should engineers review before using the SMF30A?

Engineers should confirm that the 30V standoff voltage is appropriate for the normal operating voltage of the line and that the 200W power rating handles expected surge events.

What are the sourcing risks for the SMF30A?

The component is currently active with high availability, posing low sourcing risk for standard production requirements.
