Thermoelectric cooler for photonics

27 April 2011 Circuit & System Protection

Nextreme Thermal Solutions has introduced the OptoCooler HV37 module, the next product in its high-voltage (HV) line of thin-film thermoelectric coolers (TECs) designed to address photonics cooling applications with large heat pumping requirements.

At 85°C, the module can pump 4,5 W or 107 W/cm² of heat in a footprint of only 6 mm² and a height of just 0,6 mm. AT 85°C, it can create a temperature differential (T) of up to 60°C between its hot and cold sides, and operates at a maximum voltage of 7,7 V, making it compatible with commonly found board-level currents and voltages. At 25°C, the device can create a T of up to 50°C with a maximum voltage of 5,9 V.

The OptoCooler HV37 is RoHS compliant and is manufactured using gold-tin (AuSn) solder, which enables assembly temperatures as high as 320°C. These assembly temperatures make the module compatible with industry standard processes for packaging photonics devices that require tight tolerances.
