APPLICATIONS
TVS diodes provide a low cost solution to conducted and
radiated Electromagnetic Interference (EMI) and
Electrostatic Discharge (ESD) noise problems. The noise
immunity level and reliability of FlexRay transceivers can
be easily increased by adding external TVS diodes to
prevent transient voltage failures.
The NUP2115L provides a transient voltage suppression
solution for FlexRay data communication lines. The
NUP2115L is a dual bidirectional TVS device in a compact
SOT23 package. This device is based on Zener technology
that optimizes the active area of a PN junction to provide
robust protection against transient EMI surge voltage and
ESD.
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
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 7 provides an example of a dual bidirectional
TVS diode array that can be used for protection with the
FlexRay network. The bidirectional array is created from
four identical Zener TVS diodes. The clamping voltage of
the composite device is equal to the breakdown voltage of
the diode that is reversed biased, plus the diode drop of the
second diode that is forwarded biased.
