Diodes, rectifiers and arrays are useful in a variety of applications, from current regulation to lighting control. One of the most popular components of this type is the DB4X313F0R.

Application

The DB4X313F0R is a high-voltage rectifier array intended for use in applications such as high-voltage AC power supply circuits and cinema projection systems. It features a maximum surge forward current of 6.7 amperes and a reverse voltage rating of 400 V RMS. The device also has a variety of protection features, including over-current, over-voltage, under-voltage and open-wire protection.

Design

The DB4X313F0R is a four-pin device, with one anode and three cathode pins. The anode is the center of the device, and the cathode pins are grouped together adjacent to the anode. The device has a powerful rectifier bridge design, allowing it to handle power up to 400 Volts RMS. The device can also handle a wide range of input frequencies, making it suitable for applications that require higher-power handling and universal frequency control.

Working Principle

The DB4X313F0R is designed with a number of protection features, allowing it to prevent damage from various conditions. These protection features include current, over-voltage, under-voltage and open-wire protection. If the device is subjected to excessive current, the over-current protection will immediately shut down the device. Similarly, if the device is subjected to a voltage exceeding the maximum rating, the over-voltage protection will limit the output voltage.

Likewise, the device can prevent damage from low-voltage conditions by engaging its under-voltage protection system, which limits the power draw on the device. Finally, the open-wire protection feature will detect any open wires in the circuit and shut the device off if it is necessary.

Conclusion

The DB4X313F0R is an ideal choice for applications requiring high-power handling and universal frequency control. This device features a rectifier bridge design and a wide range of protection features, which ensure reliable operation and prolonged life. Furthermore, the device is suitable for use in a variety of applications, including high-voltage AC power supplies and cinema projection systems.
