High Speed IR Emitting Diode in SMD Package
Description
TSMF1000 series are high speed infrared emitting
diodes in GaAlAs/GaAs/GaAlAs double hetero tech-
nology (DH) molded in clear SMD package with dome
lens.
DH chip technology represents best performance for
speed, radiant power, forward voltage and longterm
reliability.
