The VS-12F80 is a variation of the single-phase surface mount bridge rectifier, characterized by a low forward voltage drop and fast reverse recovery time. It is widely used in switching power adapters, battery chargers, computers and many industrial control applications. It is designed to provide substantial reduction in power losses when installed in medium- and high-power applications.

Construction and features

The VS-12F80 is a single phase bridge rectifier with a maximum operating temperature of 150°C. It is available in a small surface-mount package with a junction-to-lead thermal resistance of 0.45°C/W. The device is characterized by a fast forward voltage drop of 1.2V at 5A, a reverse current of 2mA at a reverse voltage of 15V and a recovery time of 25ns. It has low noise, low ESR and offers quick switching speed. The package also features high-speed reverse recovery characteristics, eliminating the need for snubber circuits.

Applications

The VS-12F80 is suitable for use in a wide range of switching power adapters and DC chargers, such as in printers, laptops, and cell phones. It is also well-suited for use in medical and industrial equipment and applications including light dimmer systems, UPS systems, elevator controls, and power supplies.

Working principle

The VS-12F80 works by allowing current to flow in only one direction when forward-biasing the anode and cathode. When the voltage is reversed, the diode enters a high-resistance or blocking state. This is known as the reverse-biased or blocking state.In the forward state, current flows through the device from the anode to the cathode. During the reverse state, current is blocked from the cathode and is unable to flow through the diode, thus protecting the device from possible damage due to reverse voltage. The operation is similar to that of a regular rectifier, with the exception that the reverse recovery time is much faster. This allows for faster switching of the diode, resulting in less switching losses, and higher efficiency.

Conclusion

The VS-12F80 is an efficient and reliable single-phase bridge rectifier. It is designed for use in medium- and high-power applications, and features a low forward voltage drop, a fast reverse recovery time, low noise, and a low ESR. It is suitable for use with switching power adapters, battery chargers, computers, and many industrial control applications.
