TVS Diode Protection Circuit
TVS diodes provide protection to a transceiver by
clamping a surge voltage to a safe level. TVS diodes have
high impedance below and low impedance above their
voltage of the diode that is reversed biased, plus the diode
drop of the second diode that is forwarded biased.

optimized to absorb the high peak energy of a transient

event, while a standard Zener diode is designed and
specified to clamp a steady state voltage.
Figure 7 provides an example of a dual bidirectional
TVS diode array that can be used for protection with the
high ? speed CAN network. The bidirectional array is created
from four identical Zener TVS diodes. The clamping
voltage of the composite device is equal to the breakdown
