It is an integrated bridge array that can be used to implement a variety of conversion functions. The package contains 16 individual diodes in a 4 rows – 4 columns array configuration. Its electrical and physical features include a low forward voltage drop, low leakage currents, low reverse recovery times, low thermal resistance, and a high junction temperature.

Application Field

The VS-VSKJ250-16PBF can be used in an array of applications that require a bridge configuration rectifier as a replacement for standard four-terminal rectifiers. It is well-suited for use in a variety of high-frequency rectifier circuits in such applications as power supplies, motor drives, DC-DC converters and inverters, battery charging systems and other rectification circuits.

Working Principle

The working principle of the VS-VSKJ250-16PBF is straightforward. It contains four pairs of diodes. Each pair is placed orthogonal to the other pairs in the array. In order to operate as a bridge rectifier, this diode array requires two external resistor networks and a capacitor to form a full wave bridge rectifier circuit. The first resistor network is connected to the input terminal, and it is used to provide the current limiting for the rectification process. The second resistor network is connected to the output terminal, and it is used to provide the necessary load for the circuit. Finally, a capacitor is connected between the two resistor networks in order to smooth out the ripple in the rectified output voltage.

When a full wave rectifier circuit is formed, the four diodes that make up the rectifier simultaneously draw in power from the input terminal. As diodes are bidirectional devices, each individual diode conducts in alternate half-cycles of the input waveform, while blocking current in the other half-cycle. As a result, the combined effect of the diodes is to rectify the waveform into a DC voltage at the output terminal.

Conclusion

The VS-VSKJ250-16PBF is an ideal package for use in full wave bridge rectifier circuits due to its low forward voltage drop and low thermal resistance. Its small size makes it perfect for use in a variety of battery charging and other power conversion applications. Thanks to its built-in bridge array configuration and integrated resistors, the diode array is capable of performing a wide range of rectification functions with minimal effort from the user.
