Storage

The storage and drying processes for all Vishay transceivers

(TFDUxxxx and TFBSxxx) are equivalent to MSL4. The data

for the drying procedure is given on labels on the packing

and also in the application note “Taping, Labeling, Storage

and Packing”.

CURRENT DERATING DIAGRAM

Figure 6 shows the maximum operating temperature when

the device is operated without external current limiting

resistor. A power dissipating resistor of 2

 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.
