The OptoCooler HV14 module is the first in a new class of RoHS-compliant high voltage and high heat pumping thermoelectric coolers that are designed for standard electrical power requirements.

At 85°C, the HV14 operates at a maximum voltage of 2.7V and can pump 1.5 watts of heat in a footprint of only 3 mm². The module can create a temperature differential (ΔT) of up to 60°C between its hot and cold sides, making it ideally suited for the cooling and temperature control of optoelectronic devices such as laser diodes and high brightness LEDs.

At the core of the OptoCooler module is Nextreme's breakthrough Thermal Copper Pillar Bump, a structure made from thin-film thermoelectric material embedded into flip chip interconnects (in particular, copper pillar solder bumps) used in electronic and optoelectronic packaging. Thermal bumps act as solid-state heat pumps and can add thermal management functionality locally on the surface of a chip or other electrical component. Based on market demand and recent technology advances, Nextreme has reduced the size of the thermal bump by 75%, thereby increasing voltages by 3X and reducing current draw by the same proportion as compared to devices previously configured with the same number of couples. The net result eliminates the need for special voltage conditioning and reduces the overall electrical current required to operate the device.

The new HV Series removes unique voltage and current requirements as barriers to the integration of thin-film thermoelectrics into electronics. The standard voltages and current operating ranges of the new OptoCooler HV14 fit well within the typical power design criteria for optoelectronic components and systems.

The OptoCooler HV14 is RoHS compliant and is available for order now. Pricing is available upon request.
