FAQ

What is the ESD protection rating for this component?

The device provides an ESD capability exceeding 8 kV according to the human body model and greater than 800 V according to the machine model, as specified under AEC-Q101.

How does the 'C' designation affect the component's specifications?

The 'C' in the ordering code indicates a standard Zener voltage tolerance of ±5 %. Replacing 'C' with 'B' would result in a tighter tolerance of ±2 %.

What is the maximum power dissipation on an FR-4 board?

When mounted on an FR-4 board using the recommended soldering footprint, the maximum power dissipation is rated at 300 mW.
