• Laptop and mobile power supplies
• UQM power module
• Telecommunication power supplies
• Photovoltaic systems
• High frequency switching power supplies

Working principle

The UGF8FT-E3/45 single fast recovery diode works by allowing current to flow in one direction only. An electric current is generated when the diode is forward biased and prevents current from flowing in the opposite direction when the diode is reverse biased. The ultrafast switching time of the UGF8FT-E3/45 single fast recovery diode is achieved by a special alloy construction within the diode. This construction allows for faster current reversals by reducing the time taken for minority carriers to get to the junction.

In addition, the UGF8FT-E3/45 single fast recovery diode has a low forward voltage drop, which means that the device can switch more quickly and efficiently. This reduces the power loss during switching, which leads to increased efficiency. Furthermore, the low forward voltage drop means that the voltage across the switch is of lower magnitude, reducing device stress and therefore improving the device’s reliability.

The recovery process of the UGF8FT-E3/45 is also very fast. The device’s low reverse current and fast recovery time mean that it can be used as a rectifier in applications that require a fast response time. Furthermore, the low reverse current also means that the device can be used as an indicator in fault diagnosis systems.

In summary, the UGF8FT-E3/45 single fast recovery diode is suitable for a wide range of applications such as AC/DC converters, UPS systems, and telecommunication power supplies. The device has low forward voltage drop and ultrafast switching time, allowing it to switch current quickly and efficiently while also improving reliability.
