Insulated gate bipolar transistor (IGBT) is usually used in combination with power diode in power electric circuit because it has no reverse blocking ability. In order to reduce cost and parasitic inductance. the freewheeling diode and IGBT are integrated by process method. and a reverse blocking insulated gate bipolar transistor (RB-IGBT) is thus proposed. https://bbmbatteryes.shop/product-category/108/
