DESCRIPTION
The TSOP5038 is a compact SMD IR receiver for sensor
applications. It has a high gain for IR signals at 38 kHz. The
detection level does not change when ambient light or strong
IR signals are applied. It can receive continuous 38 kHz
signals or 38 kHz bursts.

are optional
to improve the robustnes against electrical overstress
(typical
values
are R

= 0.1 µF).
The output
voltage V

should not
be
pulled down to a level
below

the external circuit.
The capacitive load at the output should
be
less than 2 nF.

ASSEMBLY INSTRUCTIONS
Reflow Soldering
• Reflow soldering must be done within 72 h while stored
under a max. temperature of 30 °C, 60
%
RH after opening
the dry pack envelope
• Set the furnace temperatures for pre-heating and heating
in accordance with the reflow temperature profile as shown
in the diagram. Excercise extreme care to keep the
maximum temperature below 260 °C. The temperature
shown in the profile means the temperature at the device
surface. Since there is a temperature difference between
the component and the circuit board, it should be verified
that the temperature of the device is accurately being
measured
• Handling after reflow should be done only after the work
surface has been cooled off

Manual Soldering
• Use a soldering iron of 25 W or less. Adjust the
temperature of the soldering iron below 300 °C
• Finish soldering within 3 s
• Handle products only after the temperature has cooled off
