Vishay Semiconductors
MECHANICAL DATA
Pinning
1 = OUT, 2 = GND, 3 = V
S
FEATURES
Low supply current
Photo detector and preamplifier in one package
Internal filter for PCM frequency
Improved shielding against EMI
Supply voltage: 2.7 V to 5.5 V
Improved immunity against ambient light
Insensitive to supply voltage ripple and noise
Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
DESCRIPTION
The TSOP48.. series are miniaturized receivers for infrared
remote control systems. A PIN diode and a preamplifier are
assembled on a lead frame, the epoxy package acts as an IR
filter.
The demodulated output signal can directly be decoded by a
microprocessor. The TSOP48.. is the standard IR remote
control receiver series, supporting all major data formats.
This component has not been qualified according to
automotive specifications.

The external components R
1
and C
1
are optional
to improve the robustnes against electrical overstress
(typical values are R
1
= 100 Ω, C
1
= 0.1 µF).
The output voltage V
O
should not be pulled down to a level
below 1 V by the external circuit.
The capacitive load at the output should be less than 2 nF.

Note
(1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating condtions for extended periods may affect the device reliability.
