GaAlAs/GaAlAs Infrared Emitting Diode in SMT Package
Description
TSMF3700 is a high speed infrared emitting diode in
GaAlAs on GaAlAs double hetero (DH) technology in
a miniature PL–CC–2 SMD package.
It has been designed to meet the increasing demand
on optoelectronic devices for surface mounting.
The package consists of a lead frame which is surrounded with a white thermoplast. The reflector inside
the package is filled up with clear epoxy.
