Application Information
CAN Bus Protection
CAN bus connections are subject to harsh transient and
noise conditions of an automobile environment. The
CAN physical layer specification requires a certain level
of noise and transient protection. However, due to the
harsh environemnet in which they operate, it is prudent
to add additional external protection in the form of low
pass filters and TVS diodes. Low pass filtering and noise
protection is achieved with some combination of RC
networks and (optional) common mode chokes. Once
added to the system, these components are also subject
to transient ESD and EOS events.
turn on in case of an indefinate short between the
automotive battery and the signal lines. It provides ESD
protection to +/-25kV contact discharge (per IEC 61000-
4-2) and EOS protection to 5A for an 8/20 μs pulse.
Typical junction capacitance is only 15pF .
A typical implementation is shown in Figure 1. The TVS
is located such that it protects the filter components as
well as the CAN transceiver. μClamp2492SQ should be
placed as close to the connector as possible.
μClamp2492SQ is a 2-Line TVS diodes specifically
designed for protection of CAN circuits. It has an
operating (working) voltage of 24V with a minimum
breakdown voltage of 26.5V. This means it will not
