VSKD320-12

Diodes – Rectifiers – Arrays

The VSKD320-12 is a diode rectifier array, specifically designed to assist in a wide range of applications. Generally, diode rectifier arrays are used to adjust, limit, and protect the output of pulse-width modulated (PWM) controllers by providing isolation, voltage regulation and ESD protection. This array can take a current rating of up to 5A and features an ultra-low dropout (UDO) rectifier with a single-channel forward current capability of up to 30V. This makes it suitable for use in a wide array of applications, including automotive electronics, industrial controllers, telecoms, and many more.

Applications

The VSKD320-12 can be used in a wide range of applications, including but not limited to;

• Automobile electronics
• Industrial controllers
• Telecoms
• Power supplies
• USB charging ports
• Battery backup systems
• High power converters
• Medical devices

The device is well suited to applications where accuracy is of the utmost importance. It has a high level of accuracy due to its single-forward channel, which provides precision voltage/current regulation and protects against voltage/current transients. This makes it ideal for use in applications such as automotive, industrial and telecoms industries.

Working Principle

The VSKD320-12 diode rectifier array includes an ultra-low dropout (UDO) rectifier with a single-channel forward current capability of up to 30V. It also features a low-noise low-dropout (LDO) precision voltage-reference circuit, which provides excellent accuracy with very low output deviations. This enables it to maintain precise voltage regulation, even under extreme conditions.

The device enables the user to adjust the voltage level at the output terminals of the main-inductor power switch with a simple, efficient, and accurate method. This helps to reduce the power dissipation of the main-inductor switch, and hence overall power losses. Furthermore, the device reduces the number of externally connected components by providing overcurrent and short circuit protection as well as overvoltage protection.

The array also features ESD protection, which prevents transients and other EMI sources from damaging the electrical components. This is especially useful in applications such as user interfaces, which are potentially exposed to electrostatic discharges. This protection mechanism enables the array to operate reliably in noisy environments, as well as helping to prolong product life.

Conclusion

The VSKD320-12 diode rectifier array is capable of providing efficient, accurate, and reliable voltage/current regulation. It is well suited to a wide range of applications including automotive, industrial and telecoms industries, thanks to its high level of accuracy, ESD protection, and effective thermal dissipation. In addition, it can reduce the number of externally connected components, thereby increasing efficiency and reducing manufacturing costs.
