Thermoelectric Cooler
DURHAM, N.C., Oct. 20, 2009 – Nextreme Thermal Solutions Inc. has announced that its OptoCooler HV14 has passed the 3000-g shock test as defined in the MIL-STD 883E Method 2002 Mechanical Shock standard.

The standard establishes uniform methods, controls and procedures for characterizing and screening microelectronic devices suitable for use within government and aerospace electronic systems. This includes basic environmental tests to determine resistance to the effects of natural elements and conditions surrounding government and space operations. The shock test is intended to determine the suitability of the devices for use in electronic equipment that may be subjected to severe shocks as a result of suddenly applied forces or abrupt changes in motion.

Nextreme-3000G.jpgMIL-STD 883E calls for five shock pulses of 3,000 g (peak) with a pulse duration of 0.3 ms in each of the orientations X1, X2, Y1, Y2, Z1 and Z2. The modules showed less than a 5% change in electrical resistance as a result of the stress testing. The test report is available to qualified customers upon request.

The use of thin films in conjunction with the company’s semiconductor-based assembly process reduces the mass of its thermoelectric coolers and makes them more resistant to shock and vibration than standard bulk devices.

The module is a high voltage and high heat pumping thermoelectric device that is designed to operate at standard electrical power requirements. At 85 °C and with a footprint of 3 mm², it operates at a maximum voltage of 2.7 V and can pump 1.5 W of heat. It can create a maximum temperature differential (ΔT) of up to 60 °C between its hot and cold sides with a zero heat load, making it suited for cooling and temperature control of optoelectronic devices such as laser diodes, avalanche photodiodes and high-brightness LEDs.

The device is RoHS-compliant.
