VS-20CTQ045-N3

The VS-20CTQ045-N3 is a diode rectifier array for high frequency switching power applications, noted for its low forward voltage drop and high continuous reverse current, designed for use in circuits requiring high frequency, high reliability and high isolation. This diode rectifier array offers a wide range of capabilities, such as high temperature operation, low capacitance and high efficiency.

Application field and Working Principle

The VS-20CTQ045-N3 diode rectifier array is commonly used in automotive, industrial and lighting applications, primarily in switched-mode power supplies (SMPS). It also finds use in applications such as sensor-triggering circuits, signal processing, and medical imaging.

In a SMPS, the VS-20CTQ045 is used to switch a power source from the DC positive input voltage to the output voltage. As current flows from the input source to the output, it is rectified by the diode. The reverse-biased diode acts as a barrier, allowing only current to flow in one direction and blocking any current from flowing in the opposite direction. The VS-20CTQ045 diode rectifier has a high voltage rating for protection against over-voltage reverse transients and spikes. The low forward voltage drop reduces power loss in the circuit and achieves high efficiency.

When the device is switched on, current will flow through the device in the forward direction. The device includes an over-temperature shutoff feature to protect the device from excessive heat and prevent damage. The diode rectifier also includes ESD protection circuits to protect against electrostatic discharge. The isolation between input and output helps to prevent instability in the circuit.

The VS-20CTQ045-N3 offers a range of features to reduce power loss and voltage overshoot and reduce noise, including transient protection and soft-start capability, and integrated temperature compensation to reduce impedance and reduce power dissipation.

The device is designed to work in a wide range of temperatures, up to 175°C, and is RoHS compliant for use in Europe and the United States.
