Electronic equipment – and the value of semiconductors — in cars is constantly growing. Modern cars, from luxury models to even entry-level vehicles, contain lots of electronic modules providing comfort, infotainment, and safety for occupants. These modules increasingly interact with each other turning cars into mobile networks.
Several different networking standards (CAN, LIN, MOST, FlexRay, Ethernet 2 wires, and others) connect the various modules and support data exchange. With this connectivity, however, comes the risk of increased damage from electrical effects such as electrostatic discharges (ESD) and electromagnetic interference (EMI). These can disrupt or damage sensitive electronic modules. The good news is that protection devices support safe and reliable functionality.
