SDC36C
TVS Diode Array for
Proximity Switch Input Protection
Description
Features
Circuit Diagram Schematic & PIN Configuration
Revision 04/01/08
The SDC36C is a high-surge transient voltage suppres-
sor (TVS) optimized for protection of sensitive digital
sensors used in proximity switches and industrial
control applications. The SDC36C protects the compo-
nents from over-voltages caused by electrostatic
discharge (ESD), electrical fast transients (EFT), and
tertiary lightning.
The unique design of the SDC36C incorporates two
TVS diodes in a compact package for applications
where board space is at a premium. The single pack-
age provides protection for the I/O line and power
supply rail with high surge capabilities (2 Amps at
t
p
=1.2/50us) and an exceptionally low clamping volt-
age of <47V.
The SDC36C replaces up to two large discrete diodes
providing the designer an easy to implement integrated
solution. The SDC36C is in a 3-pin, RoHS/WEEE
compliant, SOT-23 package. The small size and unique
features of the SDC36C make it ideal for protection of
two, three, and four wire DC high-side proximity
switches.
