GaAs is considered to be less susceptible to output degradation than GaAlAs. While the effects of degradation on both materials
are insignificant at normal operating currents (10 - 20mA), GaAs is, nevertheless, the preferable choice of material in applications
where high operating currents or temperatures are expected and long-term reliability is critical.
GaAs offers a second advantage of having lower forward voltage characteristics than GaAlAs. If large numbers of devices are to
be placed in series, or if power supply voltage is limited, the selection of GaAs over GaAlAs devices may be the best design
choice.
The two broad classifications of package types are hermetic and plastic. Each offers its own distinct advantages. In many
environments, hermetic packaging may be mandatory. It has excellent resistance to water and other solvents, while offering the
broadest operating temperature range and resistance to thermal shocks. Plastic packaging, in addition to a cost advantage over
the hermetic packaging, exhibits excellent optical properties. Overall emission efficiency is also superior because optical interfaces
are minimized. Finally, resistance to mechanical shock and vibration is excellent because both chip and bond wire are fully
encased in supportive material. Application Bulletin 208 compares these package types.
In addition to the standard products shown, OPTEK leads the industry in custom product capability. Special selections or custom
package designs may be the solution to your unique application problem. Call your local OPTEK representative for more
information.
OPTEK provides product bulk packed in bags, tubes, trays, tape and reel or tape and ammopack. All products are inspected
based upon OPTEK packing requirements as well as EIA-468 when applicable. Add “TR” suffix for Tape and Reel. Add “TA”
suffix for Tape and Ammopack. Tape and Real or Tape and Ammopack are not available on all device types, for more
information call your local representative.
