QCA150AA120 is a dual Darlington power transistor module which has series connected high speed, high power Darlington transistors. Each transistor has a reverse paralleled fast recovery diode. The mounting base of the module is electrically isolated from semiconductor elements for simple heatsink construction,

● IC＝150A, VCEX＝1200V
● Low saturation voltage for higher efficiency.
● High DC current gain hFE
● Isolated mounting base
