FAQ
What is the ESD protection capability of the AZ23C30-HE3_A-08?
According to AEC-Q101 standards, the device offers an electrostatic discharge capability of greater than 8 kV using the human body model and greater than 800 V using the machine model.
How does the 'C' designation affect the Zener voltage tolerance?
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 with the recommended soldering footprint, the maximum power dissipation is 300 mW.
