Fast Infrared Transceiver Module (FIR, 4 Mbit/s)
for 2.7 V to 5.5 V Operation
Description
The TFDU6102 is a low-power infrared transceiver
module compliant to the latest IrDA physical layer
standard for fast infrared data communication, sup-
porting IrDA speeds up to 4.0 Mbit/s (FIR), and carrier
based remote control modes up to 2 MHz. Integrated
within the transceiver module are a PIN photodiode,
an infrared emitter (IRED), and a low-power CMOS
control IC to provide a total front-end solution in a sin-
gle package.

Vishay FIR transceivers are available in different
package options, including this BabyFace package
(TFDU6102). This wide selection provides flexibility
for a variety of applications and space constraints.
The transceivers are capable of directly interfacing
with a wide variety of I/O devices which perform the
modulation/ demodulation function, including
National Semiconductor’s PC87338, PC87108 and
PC87109, SMC’s FDC37C669, FDC37N769 and
CAM35C44, and Hitachi’s SH3. TFDU6102 has a tri-
state output and is floating in shut-down mode with a
weak pull-up.
Features

9.7 mm x 4.7 mm x 4.0 mm
• Operating Temperature - 25 °C to 85 °C
• Storage Temperature - 40 °C to 100 °C
• Transmitter Wavelength typ. 886 nm, supporting
IrDA® and Remote Control
• IrDA® compliant, link distance > 1 m, ± 15 °, win-
dow losses are allowed to still be inside the IrDA®
spec.

• EMI immunity > 550 V/m for GSM frequency and
other mobile telephone bands /
(700 MHz to 2000 MHz, no external shield)
• Split power supply, LED can be driven by a
separate power supply not loading the regulated
supply. U.S. Pat. No. 6,157,476
• Tri-state-Receiver Output, floating in shut down
with a weak pull-up

1) Receive mode only.
In transmit mode, add additional 85 mA (typ) for IRED current. Add Rxd output current depending on Rxd load.

3) The typical threshold level is between 0.5 x VCC2 (VCC = 3 V) and 0.4 x VCC (VCC = 5.5 V) . It is recommended to use the specified
min/ max values to avoid increased operating current.

Current Derating Diagram
Figure 5 shows the maximum operating temperature
when the device is operated without external current
limiting resistor. A power dissipating resistor of 2 Ω is
recommended from the cathode of the IRED to
Ground for supply voltages above 4 V. In that case
the device can be operated up to 85 °C, too.
