Miniature thermoelectric coolers for high-temperature optoelectronics

03-08-2021 | Laird | Subs & Systems

Laird Thermal Systems has released its enhanced OptoTEC OTX/HTX Series of miniature thermoelectric coolers intended for high-temperature environments found in industrial, telecom, autonomous and photonics applications. Featuring next-generation thermoelectric materials, the OptoTEC OTX/HTX Series provide a 10% boost in cooling capacity, higher temperature differential and greater efficiency than standard thermoelectric coolers.

The high-performance, solid-state cooling devices are specifically created to control the temperature of heat-sensitive optoelectronic components used in laser diodes, LiDAR, optical transceivers, CMOS and IR sensor applications.

In footprints as small as 3mm X 4mm, the series provides high heat pumping capacity and enhanced temperature stability for optoelectronic applications with tight geometric space constraints. Offering up to 10W of cooling power, the series maintains a temperature differential ΔTmax (Qc = 0) of up to 82C with a hot side temperature at 50C. The product series has passed the Telcordia GR-468 CORE qualification to withstand harsh mechanical and environmental test standards, and manufacturing process controls have been improved to assure high repeatability and long-life operation.

"Temperature stabilisation of optoelectronic components in high-temperature environments is no easy task," said Andrew Dereka, Thermoelectrics product director at Laird Thermal Systems. "Our OptoTEC OTX/HTX series uses new thermoelectric materials and enhanced process controls to meet the demands of the optoelectronics industry by offering higher cooling performance in a miniature form factor."

The series is available in two versions. The OTX thermoelectric cooler is designed for operating temperatures up to 120C, while the HTX thermoelectric cooler uses a higher temperature construction to operate in temperatures up to 150C. Custom configurations are offered to suit metallisation, pre-tinning, ceramic patterns, and solder posts.
