APPLICATIONS

Background

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

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.
