QRD1420T30

QRD1420T30 is a rectifier bridge manufactured by On Semiconductor, incorporated in a PowerDI package and intended to have application in low power electronic circuits. This part includes 30V peak repetitive reverse and forward voltage(VRRM/VRFM), a forward current of up to 1.5A(IFM), an average rectified forward current of up to 1.4A(IAR), and a non-repetitive peak surge current of up to 16A(I2t).

The rectifier bridge is also designed with a reverse recovery time of up to 10ns, a storage time of up to 150ns, and an operating junction temperature of up to 150 degrees Celsius, allowing for operation in high-power applications. The QRD1420T30 is specially designed to offer a wide range of power handling capabilities, and because of its high current ratings, it can be used in a variety of low power applications.

This rectifier bridge is intended to be used in a variety of applications including AC/DC power supplies, switching power supplies, and in DC/DC converters. It can also be used in applications which require fast diode recovery times and low forward voltage drops or heat dissipation. The QRD1420T30 is compatible with both switch-mode and traditional linear power supplies and can be used to rectify both AC and DC voltage sources.

The working principle of the QRD1420T30 is based on the factor that, when the rectifier is forward biased, current flows from the anode to the cathode terminal, creating a potential difference across the device. At the same time, when the device is reverse biased, the diode does not allow current to flow. This behavior is closely related to the operation of the four diodes in the rectifier bridge.

In addition, the QRD1420T30 also contains a dual-polarity protection feature, which allows it to protect the rectifier bridge against over-voltage conditions and short circuits. The rectifier bridge provides a low voltage drop when in forward biased, which helps reduce heat dissipation, resulting in more efficient operation. Moreover, the QRD1420T30 is designed with a low thermal resistance, which helps reduce device temperatures and allows for increased efficiency in power handling.

In summary, the QRD1420T30 is a rectifier bridge designed to be used in low power applications and to provide protection against over-voltage and short circuit conditions. This device offers a wide range of power handling capabilities and has a low voltage drop when in forwardbiased. The four diodes in the bridge work together to rectify both AC and DC voltage sources, and the dual-polarity protection feature helps ensure reliable, safe operation.
