Dual Line CAN Bus Protector

NUP3105L, SZNUP3105L
Dual Line CAN
Bus Protector
The SZ/NUP3105L has been designed to protect the CAN
transceiver in 24 V systems from ESD and other harmful transient
voltage events. This device provides bidirectional protection for each
data line with a single compact SOT−23 package, giving the system
designer a low cost option for improving system reliability and
meeting stringent EMI requirements.

TVS Diode Protection Circuit
voltage of the diode that is reversed biased, plus the diode
drop of the second diode that is forwarded biased.
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
breakdown voltage. A TVS Zener diode has its junction
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 3 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
