FR85MR05 application field and working principle

The FR85MR05 is a super fast recovery type of single-phase rectifier diode, commonly used for fast-acting rectification, switching, and for clamping. It features an ultra-fast recovery time of 175ns, an average forward current of 8A as well as a peak surge current rating of 90A.

General information

The diode type specified by this type number is a single-phase rectifier. It has a high-speed rectification feature with reverse voltage (VR) ratings of 50V and 200V. It also has a moderate forward current rating of 8A, though a peak surge current of 90A. It also has a very fast recovery time of 175ns, which is optimal for switching.

Applications

This part is often used in switching applications, such as protection circuitry and clamping applications. It can also be used for the fast-acting rectification of AC signals in power supplies, lighting, and battery-charging systems. The fast 175ns recovery time of this diode makes it suitable for high-frequency switching and pulse application.

Working principle

As with other diodes, when it is forward-biased above its threshold voltage, it starts to conduct current and blocks the negative voltage signal. When it is reverse-biased, it stops conducting and starts blocking the positive signal. The fast recovery time of the FR85MR05 allows the diode to switch between conducting and blocking in a matter of nanoseconds.

The power loss through the diode occurs due to the current it passes. This is due to the small voltage drop which occurs while the diode is conducting current. The power loss through the diode is known as the forward voltage drop and it is proportional to the current that is being conducted through the diode. The lower the forward voltage drop, the lower the power losses.

Conclusion

The FR85MR05 single-phase rectifier diode is designed for fast-acting rectification, switching, and clamping applications. It features an ultra-fast recovery time of 175ns, a moderate forward current of 8A, and a peak surge current rating of 90A. This diode is suitable for protection circuitry, high-frequency switching, and pulse application. In addition, it features a low forward voltage drop for low power loss. Therefore, the FR85MR05 is a good choice for fast-acting rectification and switching applications.
