Mixed Signal Devices for Low/High
TemperatureTask 04-026
Description
Benefits
Reliability assessment of mixed signal devices
under low/high temperatures and dissemination of
this information will impact mission planners and
system designers in terms of proper electronic
component selection, optimal circuit design, and
relaxed thermal constraints.
Earth orbiting and deep space planetary
exploration missions require electronic
components and systems that can operate reliably
and efficiently in extreme temperature
environments far below or above typical
specification temperatures. These missions
include Orbital Space Plane, ISS, Space
Transportation System, Mars exploration rovers,
JWST, Europa Obiter, and Mars Flyer. This task,
through collaborative efforts between NASA
centers and JPL, will establish a database of the
reliability of mixed signal devices for use in
aerospace missions. This will be accomplished
via thorough evaluation of mission-related
devices under extreme temperatures and thermal
cycling. Safe operating areas and degradation
modes or failure mechanisms will be determined
and used to establish risk factors for use of
such devices in cold/hot space applications.

Special Commercial (L) and Aerospace (R)
Transistors for Ultra-Low Temperatures
This knowledge will result in simpler, more
robust, lighter, and more reliable systems for
space missions. These attributes will translate
into low launch costs and increased payload
capacity.
Deliverables

• Survey of NASA projects requiring operation of
  mixed signal devices at low/high temperatures.
• -Data report documenting reliability of selected
  mixed signal devices for extreme temperature
  operation.
