Diodes - Rectifiers - Arrays

DA204KT146 is a type of diode, rectifier arrray. It includes 16 individual integral diodes, able to easily provide a full-wave bridge rectifier. It is mainly used as a voltage regulator in power supplies, as well as motor controllers, UPS (Uninterruptible Power System), and automotive electrical systems. DA204KT146 is often found in power supplies of servers, video cards, and LCD monitors.

Typical Applications

DA204KT146 is extremely versatile and typically used for such applications as:

  • DC to DC voltage conversion
  • Full wave bridge rectifier
  • Battery charger
  • DC motor control
  • AC voltage regulation
  • DC adapter

Device Structure

DA204KT146 is a 4-phase bridge rectifier that includes 16 diodes in a 4x4 package. It has a built-in, error-free safety feature wherein the all 16 diodes are connected directly between the anode and cathode circuit, allowing the device to act as either a rectifier or a full wave bridge rectifier. DA204KT146 also has an extremely efficient heat dissipation, due to its ceramic packaging, making it suitable for high power applications.

Working Principle

DA204KT146 works on a simple principle of rectifying alternating current (AC) to direct current (DC). The alternating current’s continuous waveform is pushed to the rectifier, and then converted to a pulsing direct current. When the waveform of the current is at its peak, the anodes of the rectifier become positively charged and pulls the electrons towards it, creating a pulsed output as the circuit passes through the alternating current inputs.

As the current passes through the device, the 16diodes act as an obstruction, pulling electrons from anode and pushing them to the cathode. This creates a polarity change and the current flow is continuously curbed, keeping the device operating steadily. This polarity change is what allows it to switch between AC to DC rectification circuits.

Conclusion

DA204KT146 is a versatile component, finding application in motor control, full wave bridge rectifier, power supplies, and more. Its ceramic packaging and built-in safety feature make it perfect for high power applications. The integral 16 diodes enable it to convert AC to DC currents, and adjust the polarity change whenaltering between the circuits.
