Diodes - Rectifiers - Single

The introduction of the SF5400-TR comes from the semiconductor family of single-phase rectifiers, with their respective delivery parameters, making this type of diode the ideal element for all applications that require bidirectional current or pulsed voltage.

This diode is an electronic component characterized by a very low forward voltage drop and relatively low temperature coefficients, which makes it suitable for reverse polarity protection, DC converters, controlled rectifiers high efficiency switching power supplies, solid-state relays, DC-DC converters.

The traditional TO-220AB package offers a simpler solution for increased power, thermal reliability, and cost effectiveness.

SF5400-TR application field

The SF5400-TR is designed to be used in the same applications as SCHOTTKY DIODES, in addition to other applications that require:

• Low forward voltage drop.
• Low leakage current.
• High operating temperature.
• High switching speed.
• Low power dissipation.

The applications are limited to the specified parameters, such as the maximum rated reverse voltage and the maximum permissible power dissipation and temperature operation.

In general, this type of rectifier is used when low forward voltage drop, low power dissipation, and low leakage current are required. Furthermore, its switching time implies that it is suitable for high-frequency applications.

Working principle of SF5400-TR

The working principle of the SF5400-TR diode is based on the behavior of the currentthrough the diode when it is connected in forward or reverse voltage.

When a forward voltage is applied across the anode and cathode terminals, the current flows through the diode junction. The forward voltage drop (VF) is low, so the current flow is high. This low VF is usefulin applications where the diode must carry high current and dissipate low power.

When a reverse voltage is applied across the diode, the current through the diode junction is blocked. This behavior is beneficial for applications where the diodeare subjected to reverse voltage. The reverse leakage current (IR) of the SF5400-TR is low, makingit suitable for use in applications where very low leakage current is required.

Conclusion

The SF5400-TR is a single-phase rectifier with a low forward voltage drop, low leakage currentand high operating temperature, making it an excellent choice for the applications requiring theproperties mentioned above. This diode presents high reliability, good thermal stability and longlife.

In conclusion, the SF5400-TR is a reliable, cost-effective solution for applications requiringlow forward voltage drop, low leakage current and high operating temperature. It is suitable forDC converters, high efficiency switching power supplies, solid-state relays, DC-DC convertersand reverse polarity protection.
