How to measure the quality of fast recovery diode? When the fast recovery diode circuit failure, to measure the quality of fast recovery diode, this time how to do? In the amateur condition, the multimeter can be used to detect the one-way conductivity of fast recovery diode, ultra-fast recovery diode, and the internal open-circuit, short-circuit fault, and can measure the forward conduction voltage drop. If equipped with Megohm meter, can also measure the reverse breakdown voltage. Below let Ling Xun electronic take you to know how to detect the fast recovery diode.

In fact, the fast recovery diode and plastic packaging silicon diode detection method is the same, that is, the first RX1K block to test its one-way conductivity, the general forward resistance of several thousand euros, the reverse resistance is infinite; Again with RX1 block retest, general forward resistance for a few euros, reverse resistance is still infinite. If the measured resistance values are ∞ or 0, then the measured tube is damaged. The detection method of fast recovery diode is basically the same as the above method, but it must first determine which pin is the common end, and then use the above method to detect each fast recovery diode.

The Difference Between a Schottky Diode and a Fast Recovery Diode

Schottky diodes are Schottky barrier diodes, or Schottky diodes, based on the barrier formed by the contact of metals and semiconductors. In this article LX MICRO will introduce the difference between a schottky diode and a fast recovery diode.

How to Properly Apply Schottky Diode and Choose The Type

Replace the Schottky diode with the original model, because different models Schottky forward voltage drop VF and reverse breakdown voltage VR, reverse leakage current IR are different. For example, replacing MBR2045 with MBR20100, although the reverse breakdown voltage of MBR20100 is higher than that of MBR2045, does not seem to be a problem. But the forward voltage drop of MBR20100 is higher than that of MBR2045. If it is used in set-top box power circuit, it will cause + 5v and + 12V voltage deviation too much, and the power consumption will be higher than before.

SiC Schottky Compared to Normal Schottky Diode

The common Schottky diode, known as Silicon Schottky diode, is a metal-to-semiconductor diode such as MBR2045CT, MBR20100CT, and so on. It has the following advantages (or characteristics) :1.One of the advantages of silicon Schottky diode over PN junction devices is the low forward conduction voltage and low conduction loss.2.Another important performance Schottky diode is its low reverse recovery time (TRR) of 0.01 microseconds3.Silicon Schottky diode behave more like an ideal switch than PN junction devices.

Why Fast Recovery Diodes Have Higher VF

Fast recovery diode withstand voltage is above 200V. 20A fast recovery diode in the same TO-263 package, the VF at 200V is below 1V, the VF at 300V is 1.1, and the VF at 400V is 1.3. From this, we can see that the higher the withstand voltage, the higher the VF, this conclusion is valid. For those of you who still have doubts, we can also discuss the comparison between fast recovery diodes and Schottky diode.
