· igbts – fast switching – high current & high voltage what is an isolated gate bipolar transistor? before the development of the igbt, power electronics engineers had two types of device available for higher frequency switching – the bipolar junction transistor (bjt) and the metal oxide field effect transistor (mosfet).
two of the more popular versions are the metal oxide semiconductor field effect transistor (mosfet) and the insulated gate bipolar transistor (igbt). historically speaking, low voltage, low current and high switching frequencies favor mosfets. high voltage, high current and low switching frequencies, on the other hand, favor igbts.

st's power mosfet portfolio offers a broad range of breakdown voltages from –100 to 1700 v, with low gate charge and low on resistance, combined with state of the art packaging. st's process technology for both high voltage power mosfets (mdmesh™) and low voltage power mosfets (stripfet) ensures an enhanced power handling capability, resulting in high efficiency solutions.
in general, a conventional power mosfet's r ds(on) increases sharply with the breakdown voltage rating due to an increase in the thickness of the drift region required to support the high
