DESCRIPTION
The TSOP37... series are miniaturized SMD IR receiver
modules for infrared remote control systems. A PIN diode
and a preamplifier are assembled on a PCB, the epoxy
package contains an IR filter.
The demodulated output signal can be directly connected to
a microprocessor for decoding.
The TSOP374.. series devices are optimized to suppress
almost all spurious pulses from energy saving lamps like
CFLs. The AGC4 used in the TSOP374.. may suppress
some data signals. The TSOP372.. series are provided
primarily for compatibility with old AGC2 designs. New
designs should prefer the TSOP374.. series containing the
newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP372.., TSOP374.. series is designed to suppress
spurious output pulses due to noise or disturbance signals.
The devices can distinguish data signals from noise due to
differences in frequency, burst length, and envelope duty
cycle. The data signal should be close to the device’s
band-pass center frequency (e.g. 38 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP372.., TSOP374..
in the presence of a disturbance, the sensitivity of the
receiver is automatically reduced by the AGC to insure that
no spurious pulses are present at the receiver’s output.
Some examples which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent
lamps with electronic ballasts (see Fig. 13 or Fig. 14)

With Low Modulation
Fig. 14 - IR Signal from Fluorescent Lamp
With High Modulation
Notes
• For data formats with short bursts (less than 10 carrier cycles) please see the datasheet for TSOP373.., TSOP375..
• For Sony 12, 15, and 20 bit IR codes please see the datasheet of TSOP37S40

ASSEMBLY INSTRUCTIONS
Reflow Soldering
• Reflow soldering must be done within 168 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. Exercise 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

RECOMMENDED METHOD OF STORAGE
Dry box storage is recommended as soon as the aluminum
bag has been opened to prevent moisture absorption. The
following conditions should be observed, if dry boxes are
not available:
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
After more than 168 h under these conditions moisture
content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover to
the former condition by drying under the following condition:
192 h at 40 °C + 5 °C / - 0 °C and < 5 % RH (dry air / nitrogen)
or
96 h at 60 °C + 5 °C and < 5 % RH for all device containers
or
24 h at 125 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC® standard J-STD-020 level 3 label is included
on all dry bags.
