QCA50AA100 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 50A, VCEX 1000V
• Low saturation voltage for higher efficiency.
• High DC current gain hFE
• Isolated mounting base

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