Diodes - Rectifiers - Arrays

Diodes, rectifiers and arrays are an important part of many electronic systems. Diodes are used to regulate the flow of current within a device, while rectifiers are used to convert alternating current (AC) to direct current (DC). Arrays are multi-element, multiplexed rectifier circuits used to efficiently store and convert AC or DC power. In this article, we will explore the application field and working principle of a 20CTH03STRL diode array.

What is a 20CTH03STRL Diode Array?

The 20CTH03STRL is a three phase bridge rectifier array manufactured by Shindengen Electric Mfg. It is designed to provide a continuous current of up to 20 amperes. The device is rated for a peak repetitive reverse blocking voltage of 600 volts. It is made of 600 volts NPN-type transistors, and has a low power dissipation and high current carry.

Application Field

The 20CTH03STRL diode array is used in various electronic applications. It can be used as a bridge rectifier in AC/DC power supplies, as well as in frequency converters and switching regulator circuits. It is also used as a three-phase bridge rectifier in motor control applications. Additionally, the device can be used to bridge the gap between two battery supplies in highly efficient battery chargers.

Working Principle

The diode array is made up of three diodes arranged in a bridge formation. When an AC source is applied to the array, the diodes act like switches, which are alternately turned off and on as the input voltage varies. When a voltage is applied to one side of the bridge, diodes D1 and D2 are forward-biased, while diodes D3 and D4 are reverse-biased. This creates two loops of current, one flowing through D1 and D2 and the other through D3 and D4. When the input voltage changes polarity, the diode polarities reverse and the direction of current flow changes. The resulting output is a rectified DC voltage.

Advantages

The 20CTH03STRL array has a number of advantages over traditional rectifier circuits. It has a high current capacity, a low voltage drop, low internal consumption, and high noise immunity. Additionally, it can be used in high-frequency switching applications. Overall, the device provides excellent performance and high reliability in a variety of applications.

Conclusion

The 20CTH03STRL diode array is a three-phase bridge rectifier array designed to provide a continuous current of up to 20 amperes. It is used in various electronic applications, such as AC/DC power supplies, frequency converters, motor control applications, and battery chargers. The device has a high current capacity, low voltage drop, low power dissipation, and high noise immunity. In conclusion, the 20CTH03STRL diode array provides excellent performance, reliability, and flexibility in a wide range of applications.
