The QRF1220T30 rectifier array is a silicon based solid-state device which has the ability to block high voltage and current, whilst allowing conduction in the opposite direction. The device is available in a 3 pin configuration, with the addition of mounting holes and pins for easy attachment, allowing the device to be utilized in a number of applications and across an array of industries.

Rectifier diodes, such as the QRF1220T30, rectify alternating current (AC) to direct current (DC) allowing for a variety of rectifier applications. The diodes also provide protection from excessive current by simply blocking the excess current back towards its source, or in the reverse direction of the diode.

The QRF1220T30 rectifier array is commonly found in a 3-pin configuration with each terminal providing a source of alternating current, the terminal positive and negative is provided with a source of direct current. The continuous forward current rating of the device is 30 Amperes and it has a peak reverse voltage of 200V. The device is also equipped with a surge overload rating of 200 amperes giving it excellent thermal stability.

These types of rectifier diodes can be used in a variety of applications. As the QRF1220T30 device is a rectifier, it can be used in a circuit to rectify AC to DC, to rectify direct current, to provide protection from short circuit or excess current, and for grounding applications. It can also be used in a variety of industrial applications including: Motors, battery charging, solar panels, DC to AC inverters, and Uninterruptible Power Supplies (UPS).

The working principle of a QRF1220T30 rectifier diode is fairly simple. The device has two terminals, a positive and a negative terminal. Alternating current is supplied to the device from the positive terminal, and then blocked from reversing direction by the diode, resulting in only a one-way flow of current. As the direct current is then sent to the negative terminal, the two terminals are at a constant potential relative to each other with no potential difference.

The QRF1220T30 rectifier array is an essential device for applications requiring protection from excessive current and for providing direct current from AC sources. The device is widely used in a range of applications and industries, due to its ability to efficiently and reliably rectify alternating current back to direct current.
