VT2080CHM3/4W

The VT2080CHM3/4W is a series of high-speed rectifiers and arrays. It is produced by Vincotech, a semiconductor specialist providing power modules and discrete components with a focus on intelligent power applications. This semiconductor series is part of the company’s portfolio targeting lighting, power infrastructure, motion, and communications markets.

Rectifiers and arrays generated by the VT2080CHM3/4W are designed for high-frequency applications, achieving a frequency of up to 4 MHz. They are developed using high-reliability, alloyed, and optimized electrodes for power handling and temperature control. The devices are compliant with RoHS and Halogen-free environmental regulations.

The VT2080CHM3/4W series promotes a high efficiency and inclusion of soft recovery, providing a reduction of noise and a low Reverse Recovery Time (t_rr) of 30 ns. To improve its operation and performance, the rectifiers and arrays present a high surge current over voltage and temperature ranges, as well as a Junction-to-Case Thermal Resistance R_thJC value of 0.45 °C/W. In addition, the series supports both low and full voltage reverse operations.

The main application field of the VT2080CHM3/4W series is in automotive, railway and industrial systems. Typical applications include DC/DC converters, AC/DC converters, power supply applications, motor drives, fully-controlled switches, snubber applications, etc. The series also provides a high current capability for protecting power sources and for initiating low Current Interrupts (CIIs).

The working principle behind the VT2080CHM3/4W is based on the Schottky diode principle. Schottky diodes are basically silicon-barrier rectifiers and work as a two-terminal device, with a p-n junction diode between the two electrodes. They are mostly used as a rectifier and present some advantages compared to conventional p-n junction diodes such as high speed to turn on, low forward voltage drop and low reverse leakage.

The VT2080CHM3/4W allows current flow in only one direction with a closed circuit. Through the p-n junction diode, the device produces a forward voltage drop, allowing the current to start to flow. The relation between this voltage drop and the applied current is the base of the rectifier’s operation. The diode exhibits a high resistance to the current flow when a negative voltage is applied to the Anode (A) of the component, and a low resistance in the opposite direction.

In conclusion, the VT2080CHM3/4W series is a widely used component in many of the electrical and electronic circuits, mainly in the automotive, railway and industrial systems. Its series of high-speed rectifiers and arrays are designed to reach high frequencies and present a focusing on intelligent power applications, as well as a high surge current over voltage and temperature ranges. Additionally, the Schottky diode principle of the series is the base of its operation, allowing the diode to produce a forward voltage drop and permitting current flow in only one direction.
