DT-400 Series Silicon Diodes
DT-470/471 Hermetically
Sealed Silicon Diode
The DT-470/471 Silicon Diode temperature
sensors incorporate remarkably uniform
sensing elements that exhibit precise,
repeatable, monotonic temperature
response over a wide range. The elements
are mounted into rugged, hermetically-
sealed packages that have been
specifically designed for proper thermal
behavior in a cryogenic environment.
The result is a family of sensors with
temperature characteristics so predictable,
tightly grouped, and stable that the
sensors in most applications are routinely
interchangeable with one another.
DT-470/471-SD
The Lake Shore SD Package –
The Most Rugged, Versatile
Package in the Industry
The SD package, with direct sensor-to-
sapphire base mounting, hermetic seal, and
brazed Kovar leads, provides the industry's
most rugged, versatile sensors with the best
sample to chip connection. Designed so
heat coming down the leads bypasses the
chip, it can survive several thousand hours
at 500 K (depending on model) and is
compatible with most ultra high vacuum
applications. It can be indium soldered to
samples. If desired, the SD package is also
available without Kovar leads.

DT-414 Unencapsulated Silicon Diodes
The Model DT-414 uses the DT-400 bare
chip Silicon Diode mounted on a flat
substrate. This chip-level sensor offers
minimal thermal mass and minimal
physical size. Die attachment is with silver
epoxy, and the chip is
unencapsulated,
DT-414
leaving the fragile
gold wires exposed.
DT-421 Miniature Silicon Diode
The DT-421 miniature Silicon Diode
temperature sensor is configured for
installation on flat surfaces. The DT-421
sensor package exhibits precise,
monotonic temperature response over
its useful range. The sensor chip is in
direct contact with the epoxy dome,
which causes increased voltage at
4.2 K and prevents full range
Curve 10 conformity. For use
below 20 K, calibration
is required.
