Diodes - Rectifiers - Arrays

The VS-HFA08TA60C-M3 bridge rectifier is designed for active PFC boost diode applications. This part feature low forward voltage drop and recovery time, low forward power loss and inverted return that are ideal for use in PFC circuits. The device consists of a planar structure made of ultra-high performance silicon material and performs rectification of the high voltage alternating current (AC) line input.

Application fields

Applications include switch mode power supplies (SMPS), lighting, motor drives, AC/DC converters, appliances, power elimination in inverters and other circuit applications where the rectified current and voltage is applied. The PFC boost diode is used in applications where the rectified current and voltage need to be matched in order to prevent over-voltage, under-voltage or thermal over-load.

Working principle

The VS-HFA08TA60C-M3 bridge rectifier operates using the principle of reverse biased currents in the two ports which are in series. The anode voltage of one port is applied to the anode of the other port and the cathode voltage of both ports is connected. This creates a feedback loop, which limits the current flow in the reverse direction and prevents power dissipation in the device. This also ensures fast recovery time and low forward voltage drop and prevents thermal overload.

The device also features an inverse return voltage which is applied to the AC input when a forward current is passing and this causes a voltage buildup in the AC input. This makes sure that the device only accepts the desired differential voltage which prevents over-voltage or under-voltage issues. This feature also works in cases of high impedance in the AC input.

Conclusion

The VS-HFA08TA60C-M3 bridge rectifier is a modern device which is designed for active PFC boost diode applications. It features low forward voltage drop and recovery time, low forward power loss and inverted return which means it is ideal for use in PFC circuits as it prevents over-voltage, under-voltage or thermal over-load. With its fast recovery time and reverse biased currents, it is highly reliable for providing power elimination in inverters and other circuit applications.
