Description
The µClamp
®
3601P is a high-surge transient voltage
suppressor (TVS) optimized for protection of sensitive
digital sensors used in proximity switches and industrial
control applications. The µClamp3601P protects the
components from over-voltages caused by Electro-
Fast Transients
Static Discharge (ESD), Electrical F ast Transients
(EFT), and Ter tiar y Lightning
ertiar Lightning.
tiary
The µClamp3601P features a working voltage of 33
volts with a minimum breakdown voltage of 34 volts.
They are rated to handle a continuous forward current
of up to 260mA with a low forward voltage drop of less
than 1 volt (IF = 200mA). They are designed with high
surge capability (2 Amps at t
p
=1.2/50us) and a low
clamping voltage of <60V.
The µClamp3601P is in an 2-pin SLP1006P2 package.
It measures 1.0 x 0.6 x 0.5mm. The leads are spaced
at a pitch of 0.65mm and are finished with lead-free
NiPdAu. Each device will protect one line operating at
33 volts. The small size and unique features of the
µClamp3601P make it ideal for protection of DC high-
side proximity switches in industrial and automotive
applications.
The µClamp3601P is qualified to AEC-Q100 Grade1.

Applications Information
Device Connection for Protection of Two, Three, and
Four Wire Proximity Switches
Digital sensors help to bridge the gap between the
physical world and the digital world in applications such
as computer controlled factory automation. In such
environments, transient voltages can easily disrupt or
damage sensitive sensor inputs. The µClamp3601P
provides transient voltage protection for the digital
sensors to ESD, lightning, and CDE events.
The µClamp3601P is designed to meet the high surge
capability and low clamping voltage needed to protect
the ASIC and control logic used in proximity switches.
The µClamp3601P provides protection for the power
and I/O lines.
