11.2.2.1 Transient Protection

Typical applications that use CAN will sometime require some form of ESD, burst, or surge protection performance at the system level. If these requirements are higher than those of the device some form of external protection may be needed to shield the transceiver against these high power transients that can cause damage. Transient voltage suppressor (TVS) are very commonly used and can help clamp the amount of energy that reaches the transceiver.
