Nextreme Thermal Solutions is now offering an updated version of its OptoCooler HV14 that enables assembly temperatures as high as 320°C. These assembly temperatures make the HV14 compatible with eutectic gold-tin (AuSn) solder, such as that found in laser diodes, semiconductor optical amplifiers and sensors.
The OptoCooler HV14 module is a high heat pumping thermoelectric device that is designed for standard electrical power requirements. At 85°C, the HV14 operates at a maximum of 2.7V and can pump 1.7W of heat in a footprint of only 3mm². The module can create a temperature differential of up to 50°C between its hot and cold sides, making it suitable to cooling and temperature control of optoelectronic devices such as laser diodes.
