Description
The ESDLIN1524BJ is an asymmetrical
TRANSIL diode designed specifically for
protecting one automotive LIN bus line against
electrostatic discharge (ESD). The SOD-323 is a
very small package which allows space saving on
high density printed circuit board .
Transil diodes provide high overvoltage protection
by clamping action and have instantaneous
response to transient overvoltages.

In order to meet environmental requirements, ST offers these devices in ECOPACK
packages. These packages have a lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
