On releases IGBT power modules

Amongst a flurry of announcements, On Semiconductor has introduced 1.2kV 25, 35, and 50A transfer-moulded IGBT power modules – in converter-inverter-brake (CIB) and converter-inverter (CI) configurations. Transfer-moulded encapsulation extend cycling lifetime for both temperature and power, according to On. The modules consist of six 1.2kV IGBTs, six 1.6kV rectifiers, and an NTC thermistor for system ...

SMD part sucks heat from hot spots

Vishay has released a series of surface-mount thermal jumper chip that transfer heat from electrically isolated components by providing a thermal conductive pathway to a ground plane or common heatsink. Called THJP and branded ThermaWick, they have an aluminium nitride substrate with 170W/mK thermal conductivity. By pulling heat across the electrical isolation barrier, they reduce the temperature ...
