Introduction

The UPR20E3/TR13 is a single rectifier diode designed for performing voltage regulation. It is designed for applications requiring high current, low reverse leakage and low forward voltage drop, making it suitable for applications such as ultra-fast operating switching mode power supply (SMPS) applications and LED light driver circuits. This rectifier has a maximum repetitive peak reverse voltage of 20V, a maximum forward current of 0.3A, a maximum forward voltage drop of 1.1V, and a maximum reverse current of 10uA.

Application Field

The UPR20E3/TR13 single rectifier diode can be used in a wide range of electronic applications, including:

• Applying voltage regulation to audio amplifiers
• Switching Mode Power Supplies
• LED Lighting Drivers
• High voltage barriers
• DC-DC Converters

In each of these applications, the diode is used to limit the voltage to the desired levels for best performance.

Working Principle

The UPR20E3/TR13 single rectifier diode works on the principle of resistance. In order to achieve the desired level of voltage regulation, it needs to have a certain level of resistance between its two legs. This resistance level is determined by the diode\'s forward voltage drop and reverse leakage.

When the diode is forward biased (i.e., when the voltage applied to its anode is higher than that applied to its cathode), current flows in the direction of the anode. The forward voltage drop of the diode is the voltage needed to forward bias the diode enough to allow current to flow. This voltage drop is usually around 1.1V for a UPR20E3/TR13 diode.

The reverse leakage of the diode is the current that flows back in the opposite direction when the diode is reverse biased (i.e., when the voltage applied to its anode is lower than that applied to its cathode). The reverse leakage of the UPR20E3/TR13 is typically around 10uA.

The combination of these two parameters, the forward voltage drop, and the reverse leakage allow the diode to be used for voltage regulation. By controlling the amount of voltage applied to the diode, the desired level of resistance can be achieved, allowing the diode to regulate the voltage at the desired level.

Conclusion

The UPR20E3/TR13 single rectifier diode is an ideal solution for a wide variety of voltage regulation applications, due to its high current, low forward voltage drop and low reverse leakage. It can be used in a variety of electronic circuits, including audio amplifiers, SMPS, LED lighting drivers, high voltage barriers and DC-DC converters, for best performance.

The diode works on the principle of resistance, with its forward voltage drop and reverse leakage determining how much resistance is needed for a given application. By applying the correct voltage to the diode, the desired level of resistance can be achieved, allowing the diode to regulate the voltage at the required level.
