Diodes - Rectifiers - Single

The SE20PDHM3/85A is a silicon rectifier diode designed to provide excellent performance in a wide range of applications. It is commonly used as a rectifier in applications such as power supplies, chargers, and other power control systems. It has multiple advantages over traditional rectifier diodes, such as faster switching speeds, lower on-state resistance, and greater current handling capability. Additionally, the SE20PDHM3/85A is able to provide effectively zero reverse recovery current, eliminating the need for a snubber circuit and reducing power dissipation.

Application Field

The SE20PDHM3/85A rectifier diode is primarily used in power control applications, such as power supplies, chargers, and switching power converters. It is able to support a wide range of input voltages and currents, making it suitable for use in a variety of rectifier circuits. Additionally, the diode has a low forward voltage drop, allowing it to operate effectively at high frequencies and high temperatures. The low forward voltage drop also reduces power dissipation.

The SE20PDHM3/85A is also suitable for use in high-power applications, such as motor control and other switching power supplies. Its low on-state resistance and high current handling capability make it well-suited for use in power converters that require high switching speeds and high current handling levels. Additionally, its low reverse recovery current reduces power dissipation and improves efficiency.

Working Principle

The SE20PDHM3/85A is a silicon rectifier diode which works by allowing current to flow in only one direction. It consists of two semiconductor layers, one being an anode and the other being a cathode. The anode is the positive terminal while the cathode is the negative terminal. When the applied voltage is positive with respect to the cathode, current will flow from the anode to the cathode. When the applied voltage is negative with respect to the cathode, there will be no current flow.

The SE20PDHM3/85A uses a unique PN junction to create a low forward voltage drop when conducting. This allows it to support a wide range of input voltages and currents, as well as high operating frequencies and temperatures. Additionally, the diode has a low reverse recovery current, eliminating the need for a snubber circuit, and reducing power dissipation. This makes it suitable for use in high-power, switching applications.

Conclusion

The SE20PDHM3/85A is a valuable addition to the family of rectifier diodes. It offers many advantages over traditional rectifier diodes, including a wide range of supportable voltages and currents, faster switching speeds, lower on-state resistance, and greater current handling capability. Additionally, its low reverse recovery current eliminates the need for a snubber circuit, reducing power dissipation and improving efficiency. This makes it suitable for use in a variety of applications, including power supplies, chargers, and other power control systems.
