Fault Protection
All of LTC’s RS485 products are protected against ESD
transients up to
±
2kV using the human body model
(100pF, 1.5k
). However, some applications need greater
protection. The best protection method is to connect a
bidirectional TransZorb
from each line side pin to ground
(Figure 12).
A TransZorb
is a silicon transient voltage suppressor that
has exceptional surge handling capabilities, fast response
time, and low series resistance. They are available from
General Semiconductor Industries and come in a variety of
breakdown voltages and prices. Be sure to pick a break-
down voltage higher than the common-mode voltage
required for your application (typically 12V). Also, don’t
forget to check how much the added parasitic capacitance
will load down the bus.
