Frequently Asked Questions
What transient voltage levels can the device protect against?
It provides ESD immunity for both contact discharge (> 20 kV) and air discharge (> 30 kV).
How does the BiAs mode function?
It protects one signal or data line by clamping positive transients to the ground and managing negative transient current flow.
What is the component's maximum operating temperature range?
The junction temperature (T) can operate from -40°C to +125°C.
Can this component be used in RoHS compliant products?
Yes, it is a Lead (Pb)-free component in accordance with both RoHS 2002/95/EC and WEEE 2002/96/EC.
