Description
TSSF4500 is a high speed infrared emitting diode in GaAlAs on GaAlAs double hetero (DH) technology, molded in a clear, untinted plastic package with spherical side view lens.
The new technology combines the high speed of DH– GaAlAs with the efficiency of standard GaAlAs and the low forward voltage of the standard GaAs technology.

FEATUREs
● High modulation bandwidth (10 MHz)
● Extra high radiant power and high radiant intensity
● Low forward voltage
● Suitable for high pulse current operation
● Angle of half intensity ϕ = ± 22

● Peak wavelength
p = 870 nm
● High reliability
● Good spectral matching to Si photodetectors

APPLICATIONs
    Infrared high speed remote control and free air data transmission systems with high modulation frequencies or high data transmission rate requirements.
    TSSF4500 is ideal for the design of transmission systems according to IrDA requirements and for carrier frequency based systems (e.g. ASK / FSK – coded, 450 kHz or 1.3 MHz).
