Frequently Asked Questions
What is the ESD protection level for the PESD1CAN diode?
It offers ESD protection of up to 23 kV and provides bidirectional protection for two CAN bus lines.
Can these diodes be used in automotive FlexRay systems?
Yes, the PESD1FLEX feature offers protection for two FlexRay lines of one line mode, meeting MIL-STD-883 class 3 standards.
Which variant is best for protecting a single LIN bus line with common cathode configuration?
The MMBZ27VCL diode can be used for unidirectional transient overvoltage protection suitable as a common cathode configuration in an SL or RWM application.
