DESCRIPTION
1, 4 = GND, 2 = VS, 3 = OUT
The TSSP77P38 series are two lens miniaturized receivers
for Mid range proximity sensor systems. A PIN diode and a
preamplifier are assembled on a lead frame, the epoxy
package acts as an IR filter.
The output pulse width of the TSSP77P38 has an almost
linear relationship to the distance of the emitter or the
distance of an reflecting object. The TSSP77P38 is
optimized to suppress almost all spurious pulses from
energy saving fluorescent lamps.
This component has not been qualified according to
automotive specifications

Vishay Semiconductors
The typical application of the TSSP77P38 is a reflective sensor with analog information contained in its output. Such a sensor
is evaluating the time required by the AGC to suppress a quasi continuous signal. The time required to suppress such a signal
is longer when the signal is strong than when the signal is weak, resulting in a pulse length corresponding to the distance of an
object from the sensor. This kind of analog information can be evaluated by a microcontroller. The absolute amount of reflected
light depends much on the environment and is not evaluated. Only sudden changes of the amount of reflected light, and
therefore changes in the pulse width, are evaluated using this application.

The logarithmic characteristic of the AGC in the TSSP77P38
results in an almost linear relationship between distance and
pulse width. Ambient light has also some impact to the pulse
width of this kind of sensor, making the pulse shorter.

ASSEMBLY INSTRUCTIONS
Reflow Soldering
Manual 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
• Use a soldering iron of 25 W or less. Adjust the
temperature of the soldering iron below 300 °C
• 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
• Handle products only after the temperature has cooled off
• Finish soldering within 3 s
• Handling after reflow should be done only after the work
surface has been cooled off
