APPLICATIONS
Background
suppression solution for CAN data communication lines.
The ESDONCAN1 is a low capacitance dual bidirectional
TVS device in a compact SOT-23 package especially
suitable for CAN2.1 (CAN-FD). This device is based on
Zener technology that optimizes the active area of a PN
junction to provide robust protection against transient EMI
surge voltage and ESD. The ESDONCAN1 has been tested
to EMI and ESD levels that exceed the specifications of
popular high speed CAN networks.
The Controller Area Network (CAN) is a serial
communication protocol designed for providing reliable
high speed data transmission in harsh environments. TVS
diodes provide a low cost solution to conducted and radiated
Electromagnetic Interference (EMI) and Electrostatic
Discharge (ESD) noise problems. The noise immunity level
and reliability of CAN transceivers can be easily increased
by adding external TVS diodes to prevent transient voltage
failures. The ESDONCAN1 provides a transient voltage
