Description
Features
u Transient protection for proximity sensors.
The µClamp®3603T is a high-surge transient voltage
suppressor (TVS) optimized for protection of sensitive
digital sensors used in proximity switches and industrial
control applications. The µClamp3603T protects the
components from over-voltages caused by ElectroStatic Discharge (ESD), Electrical FFast
ast TTransients
ransients
tiar
(EFT), and Ter
ertiar
tiaryy Lightning
Lightning.
The µClamp3603T features a working voltage of 36
volts with a minimum breakdown voltage of 37 volts.
They are rated to handle a continuous forward current
of up to 200mA with a low forward voltage drop of less
than 1 volt (IF = 200mA). They are designed with high
surge capability (2 Amps at tp=1.2/50us) and a low
clamping voltage of <65V.
The µClamp3603T is in a 6-pin SLP1710N6T package.
It measures 1.7 x 1.0 x 0.4mm. The leads are spaced
at a pitch of 0.55mm and are finished with lead-free
NiPdAu. Each device will protect three lines operating
at 36 volts. The small size and unique features of the
µClamp3603T make it ideal for protection of DC highside and low-side 3 wire proximity switches in industrial
and automotive applications.
The µClamp3603T is qualified to AEC-Q100 Grade 1
for Automotive use.

Three Wire Proximity Switches
2-Wire DC Proximity Switch Application
Digital sensors help to bridge the gap between the
physical world and the digital world in applications such
as computer controlled factory automation, automotive spark timing and throttle position sensing amongst
others. In such environments, transient voltages can
easily disrupt or damage sensitive sensor inputs. The
uClamp3603T provides transient voltage protection
for the digital sensors to ensure their operation is not
disrupted by the physical world.
+V
SENSOR
(ASIC)
The uClamp3603T 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 uClamp3603T provides protection for the power
and I/O lines. Typical configurations for the protection
of two and three wire switches are illustrated:

Circuit Board Layout Recommendations for
Suppression of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines
are recommended:
u Place the TVS near the input terminals or connectors to restrict transient coupling.
u Minimize the path length between the TVS and the
protected line.
u Minimize all conductive loops including power and
ground loops.
u The ESD transient return path to ground should be
kept as short as possible.
u Never run critical signals near board edges.
u Use ground planes whenever possible.
