Discussion Overview

The discussion centers around the use of RF101 diodes in low-frequency recovery circuits, specifically exploring whether they can effectively replace standard rectifier diodes in such applications. Participants discuss the implications of diode characteristics, including voltage drop and thermal performance, in the context of a specific project involving high voltage requirements.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes that RF101 diodes are less common and questions their suitability for low-frequency recovery circuits, emphasizing the importance of withstand voltage.
  • Another participant raises the concern that the voltage drop across the RF101 may be higher than that of a common rectifier diode, which could lead to increased heat generation.
  • There is a suggestion that the RF101 could replace an IN4001 rectifier diode, but the implications of this replacement are not fully explored.
  • Participants discuss the need for an understanding of electrical and safety issues due to the high voltage involved in the project.
  • One participant expresses a lack of understanding regarding circuit diagrams, indicating a potential barrier to deeper technical discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the suitability of the RF101 diode as a replacement for rectifier diodes, and there are varying levels of understanding regarding the technical aspects of the project.

Contextual Notes

The discussion lacks detailed circuit diagrams and specific performance metrics for the RF101 diode compared to standard rectifier diodes, which may limit the ability to fully assess the proposed substitution.

How to use RF101 Diode? How to understand recovery diode and rectifier diodes
Hello! This is my first post.
Problem to use RF101 Diode: There is little RF 101 diode that I can search for.

And I have a project about the recovery circuit. but the frequency of the rectifier circuit is very low, it only has requirements for the withstand voltage. As long as the withstand voltage can meet, it can definitely be substituted, and fast recovery diodes are also used for rectification, that is, in the secondary rectification part of the switching power supply, due to the frequency High, only use fast recovery diodes for rectification, otherwise the overall efficiency of the power supply will be reduced due to excessive diode losses, and the diodes will be burned in severe cases. In addition, the price of fast recovery diodes is much more expensive than rectifier diodes. The higher the withstand voltage, the more expensive it is, so it is generally not used with fast recovery second-generation tubes.
Is there anyone who have ideas for it? Thanks in advance.

And I have a project about the recovery circuit.
Welcome to PF.
What project do you have?
Do you have a circuit diagram?
 
the project is whether the recovery diode can take a replacement of rectifier diodes? I do not have a circuit diagram! Because I can not understand them.:sorry:
 
The voltage drop across the RF101 is higher than the drop across a common rectifier diode. That may not be a problem if used to rectify a low current at high voltage.
The RF101 may operate hotter than the original diode.

What part number rectifier diode will the RF101 replace?

Is this a repair of one unit?
Or, will many units be manufactured?

Since this problem involves high voltages, you need to involve an engineer who does understand the electrical and safety issues.

Yes, it is.
 
I got it.
Thanks a lot!
