QCA150A and QBB150A is a dual Darlington power transistor module with two high speed, high power Darlington transistors. Each transistor has a reverse paralleled fast recovery diode.

● QCA150A…Series-connected type
  QBB150A…Separate Type
● IC＝150A, VCEX＝400/600V
● Low saturation voltage for higher efficiency.
● Isolated mounting base
● VEBO 10V for faster switching speed.

(Applications)
  Motor Control（ VVVF）, AC/DC Servo, UPS, Switching Power Supply, Ultrasonic Application
