UF5408 Recovery Diode Datasheet, Pinout, Features and Applications
Hi Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to UF5408.
The UF5408 is an ultra-fast recovery diode that comes with quick recovery time. It is mainly used to rectify the sine waves. Upon rectifying the signal it converts the AC signal into a DC signal. This diode provides the DC signal to the electronic device since most of the electronic devices operate on the DC signal.
Just stay with me for a little while as I’ll discuss the complete Introduction to UF5408 covering datasheet, pinout, features, and applications of this component UF5408.
Let’s get started.
Introduction to UF5408
- The UF5408 is a recovery diode that carries quick recovery time and is mainly used to convert the AC signal into DC signal.
- Upon turning the AC signal to the DC signal diode requires a certain amount of time during which this rectification happens. This time is known as recovery time. And this diode exhibits an extremely good recovery time of 75ns.
- The average rectified current of UF5408 is 3A and the peak repetitive reverse voltage is 1000V. The maximum reverse current is recorded at 0.010mA and the maximum RMS reverse voltage is 700V.

UF5408 Pinout
- The UF5408 diode comes with two terminals called anode and cathode. The current moves from the anode to cathode.
- The following figure represents the pinout diagram of UF5408.
- The anode side is positive through which current enters the diode and the cathode terminal is negative through which current leaves the diode.
- You can identify the cathode side simply by looking at the diode. The area with the grey colored band is the cathode side and the other is the anode.
UF5408 Working
- The time of each cycle of the signal is inversely proportional to the frequency of the signal. The more the time of the cycle, the shorter the frequency of the signal and vice versa.
- The following figure shows the comparison of the recovery time of normal diode and fast recovery diode.
- When time is shorter it means the frequency of the signal is very high and less time the diode requires to recover from each cycle.
- At very high frequencies it becomes very difficult for the diodes to quickly recover from each cycle. In such cases, the normal diode fails to quickly recover the signal since it finds it hard to swiftly respond to such short duration spikes.
- A fast recovery diode like UF5408 is applied in such cases to quickly respond to these short duration spikes and recover the signal.
- An ordinary diode takes microseconds to recover and is suitable for low-frequency applications. However, in high-frequency applications, a fast recovery diode is used that comes with a recovery time of a few nanoseconds.
UF5408 Features
- Average Rectified Current (Io) = 3.0A

UF5408 Applications
- Used for the rectification of the signal.
- Widely used in high-frequency applications.
- Can be employed as a charge controlled switch.
