Insulated Gate Bipolar Transistor with NTC Thermistor chip


An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch which, as it was developed, came to combine high efficiency and fast switching

It switches electric power in many applications: variable-frequency drives (VFDs), electric cars, trains, variable speed refrigerators, lamp ballasts, air-conditioners and even stereo systems with switching amplifiers.

Since it is designed to turn on and off rapidly, amplifiers that use it often synthesize complex waveforms with pulse-width modulation and low-pass filters. In switching applications modern devices feature pulse repetition rates well into the ultrasonic range—frequencies which are at least ten times the highest audio frequency handled by the device when used as an analog audio amplifier.


Base on what it mentions for IGBT as above.But you know In IGBT mould there is a very small components on it to measure or control the temperature.

That is Exsense Factory DT series NTC thermistor chip, it has Ag and Au plated. The feature is high accuracy, high reliability and high sensitivity. This type thermistor chip is just suitable for IGBT mould.
