QCA50B and QCB50A are dual Darlington power transistor modules which have series-connected high speed, high power Darlington transistors. Each transistor has a reverse paralleled fast recovery diode.

● IC 50A, VCEX 400/600V
● Low saturation voltage for higher efficiency.
● Isolated mounting base
● VEBO 10V for faster switching speed.
