This device features high surge capability and high rectification efficiency, making it a suitable choice for many DC applications including welding inverters, power supplies and other power-conversion equipment.

General Descriptions

The VS-87HF120 is a full-wave bridge rectifier composed of two integrated power diodes, each rated with a maximum peak repetitive reverse voltage of 1200V. Its maximum forward surge current rating is 8A, maximum forward voltage drop is 1.25V at 2A, and maximum bridge current is 8A. Its operating junction temperature range is -40°C to 125°C, allowing it to thrive in a wide range of applications and environments.

Application Field and Working Principle

The VS-87HF120 is designed for applications that require large amounts of power, such as motor-starting circuits and welding inverters. Its high efficiency and surge capability make it a perfect choice for these applications.The VS-87HF120 rectifier works by converting AC power to DC power. The alternating current from the AC source passes through the bridge and is converted to unidirectional current in the form of DC power.The device uses two diodes connected in opposite directions that switch on and off as the current passes through them. When the current passes through the first diode, it will forward bias it and allow it to conduct. As the current flow then reverses direction, the second diode will become forward biased and allow the current to flow through it. This process is repeated, creating a unidirectional current.The VS-87HF120 rectifier also features a number of protection devices, such as an in-line fuse and a protective circuit that limits the output current and keeps the device from overheating.

Conclusion

The VS-87HF120 single diode bridge rectifier is a popular device that is suitable for a wide variety of applications due to its high surge capability, high efficiency, and protection features. It is perfect for motor-starting circuits and welding inverters, and its wide operating temperature range allows it to thrive in many different environments.
