Nextreme Thermal Solutions has introduced its OptoCooler HV37 module, the next product in its high-voltage (HV) line of thin-film thermoelectric coolers (TECs) for photonics applications with larger heat pumping
requirements. At 85°C, the OptoCooler HV37 can pump 4.5W or 107W/cm2 of heat in footprint of only 6mm2. The device is only 0.6mm high, making it one of the thinnest heat-pumping TECs in the photonics market today.
At 85°C, the OptoCooler HV37 can create a temperature differential (ΔT) of up to 60°C between its hot and cold sides, and operates at a maximum voltage of 7.7V, making it compatible with commonly found board-level currents and voltages. At 25°C, the device can create a ΔT of up to 50°C with a maximum voltage of 5.9V.
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 HV37 module compatible with industry standard processes for packaging photonics devices that require tight tolerances.
