Diodes are semiconductor devices that allow current to travel in only one direction. They are used in many applications, such as rectification, voltage regulation, as switches, and to protect circuits from overloads. Rectifiers are circuits or components used to convert alternating current (AC) to direct current (DC). These are mainly used in power supplies and signal processing devices. Diodes can be used to construct rectifier circuits, in order to block or pass current in the desired direction. Arrays are collections of individual components to form a single unit, which can be controlled or operated together. It may also refer to several input/outputs connected in a parallel or series configuration.

The VS-VSKD270-12PBF is a Diode Array from Vishay Semiconductor. It is a surface-mount rectifier featuring an 8-pin simplified perpendicular form factor package, and is suitable for use in a wide range of applications. It consists of two series-connected, discrete rectifying diode circuits, with each circuit capable of supporting the reverse blocking voltage of 27 V. By allowing forward currents up to 1.2 A, its compact size and surface-mountable design makes it useful for a wide range of applications.

Working Principle

The VS-VSKD270-12PBF is a dual-opposed surface-mount rectifier with two discrete rectifying diodes connected in series to provide a blocking voltage of 27 V. Its forward current rating is up to 1.2 A. It operates according to the same principles as a single diode rectifier. In the on-state, when a forward voltage is applied, electrons easily pass through the diode and a current flows through the diode. In the off-state, when a reverse voltage is applied, the barrier formed by the depletion layer prevents the reverse flow of electrons, so the current is blocked. In the on-state, the forward voltage drop is around 0.7 V.

Application Fields

The VS-VSKD270-12PBF is suitable for a wide range of applications including:

• Signal processing/filtering
• Power management
• Lighting systems
• Automotive electronic systems
• Power supplies
• Battery charging
• Switching applications

Due to its low forward voltage drop, the VS-VSKD270-12PBF is well-suited to a variety of hot-swappable and high-efficiency switching applications, where fast transitions between states are required. It can also be used in applications where high-speed switching is needed, such as in power supplies, motor controls, lighting, and other applications where current flows need to be regulated and/or switched rapidly.

The VS-VSKD270-12PBF can also be used in power management applications, such as in laptops, cell phones and other portable electronic devices, as well as for other low-voltage, high-power applications. It can also be used in automotive electronic systems, such as in the light dimmer circuit of a car, as well as in power supplies, battery charging and other applications.
