APPLICATIONS SECTION

The NUP1105L provides a transient voltage suppression
solution for the LIN data communication bus. The
NUP1105L is a dual bidirectional TVS device in a compact
SOT−23 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. The NUP1105L has been tested to EMI and ESD
levels that exceed the specifications of popular high speed
LIN networks.
