Typical values are for design aid only, not guaranteed nor subject to production testing.
Equivalent to IrDA background light and electromagnetic field test: fluorescent lighting immunity.
IrDA sensitivity definition: minimum irradiance E
the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length.
Maximum irradiance E
intensity in angular range at minimum link length must not cause receiver overdrive distortion and possible ralated link errors. If placed at the
active output interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER). For more definitions see the
document “Symbols and Terminology” on the Vishay website.
Using an external current limiting resistor is allowed and recommended to reduce IRED intensity and operating current when current reduction
is intended to operate at the IrDA low power conditions. E.g. for V
minimized operation at IrDA low power conditions.
Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for the standard
remote control applications with codes as e.g. Phillips RC5/RC6

profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike
(RTS). The Ramp-Soak-Spike profile was developed
primarily for reflow ovens heated by infrared radiation. With
widespread use of forced convection reflow ovens the
Ramp-To-Spike profile is used increasingly. Shown in
figure 2 is Vishay’s recommended profiles for use with the
TFBS4711 transceivers. For more details please refer to the
application note “SMD Assembly Instructions”.
Wave Soldering
For TFDUxxxx and TFBSxxxx transceiver devices wave
soldering is not recommended.
Manual Soldering
Manual soldering is the standard method for lab use.
However,
recommended because the risk of damage is highly
dependent on the experience of the operator. Nevertheless,
we added a chapter to the above mentioned application note,
describing manual soldering and desoldering.
