ST. LOUIS, July 31, 2012 — The eTEC series thermoelectric modules from Laird Technologies Inc. enable high-power optoelectronics and laser diodes to maintain peak performance by stabilizing the temperature of the devices during operation. They are assembled using thin-film technology that provides 10 times more heat pumping density per unit area than conventional bulk thermoelectric technology delivers. The ceramic substrates are gold-metallized to allow them to be embedded into densely packed optoelectronics.

The modules’ heat-pumping densities range from 75 to 90 W/cm2 at an ambient temperature of 25 °C. The new models include:

HV14, 18, F0, 0101, GG – 1.4 W in 1 mm2
HV37, 48, F2, 0202, GG – 3.7 W in 6.9 mm2
HV56, 72, F2, 0203, GG – 4.8 Win 10.2 mm2

Constructed with bismuth telluride thin-film technology and thermally conductive aluminum nitride ceramics, the modules are designed for higher voltage and lower, sub-10-W heat pumping applications. Other features include RoHS-compliance, pending Telcordia-compliance and gold metallization for soldering to substrate surfaces.

GLOSSARY
optoelectronics
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
