THJP surface mount chips are designed to provide an
electrically isolated thermal conductive pathway to a ground
plane or heat sink while maintaining the electrical isolation of
the device. The devices are constructed with aluminum
nitride substrates in both SnPb and Pb-free wraparound
termination styles. The low capacitance of the device makes
them an excellent choice for high frequency and thermal
ladder applications. Custom sizes available.

HEAT TRANSFER DEMONSTRATION
Chip surface temperature was measured using a FLIR SC645 thermal imaging system under ambient conditions. The devices
were mounted to an FR4 test card designed with a 25 mm x 19 mm copper heat sink. Power was supplied to device to cause
the surface temperature to stabilize at 150 °C. The device was then retested at the same power level with the thermal jumper
connecting the device to the heat sink.
