SE15FD-M3/I

The SE15FD-M3/I is part of the family of single-phase rectifiers and is designed for a variety of applications. It consists of a diode and a freewheeling diode in a single package, typically used for power supplies, battery chargers, electronic ballasts, and bridge rectifier circuits. It’s designed to handle heavy transients up to 400V and can be used for a wide range of voltage applications.

About the Product

The SE15FD-M3/I is a rectifier diode package with a maximum rated average forward current of 3A, a non-repetitive peak forward surge current of 10A, reverse voltage of 200V, and reverse recovery time of 200ns. It is coated in heat-resistant epoxy resin to increase its thermal and electrical stability. The package is designed to dissipate heat effectively, ensuring the temperature of the device doesn\'t exceed the operating level.

Applications

The SE15FD-M3/I is ideal for a range of applications, including:

• Power supplies
• Battery chargers
• Electronic ballasts
• Bridge rectifier circuits

These types of applications require a rectifier which can effectively handle high voltage transients, and the SE15FD-M3/I is capable of delivering this. Its high current rating provides exceptional performance, allowing it to handle up to 400V with ease.

Working Principle

Rectifiers are commonly used in power electronics, and they work by converting AC power into DC power. The working principle behind the SE15FD-M3/I is very simple. The diode package consists of two diodes; the anode connects to the positive terminal and the cathode to the negative terminal. When an AC voltage is applied to the package, the diodes will conduct during alternate half cycles of the AC voltage and provide a full-wave DC power output.

The two diodes of the package combine to form a bridge rectifier circuit, resulting in the formation of a full-wave rectified voltage. This rectified voltage has a ripple, which is caused by the alternate reverse-biasing of the diodes. In order to reduce the ripple and to get a smoother DC voltage, a filter capacitor is usually added in parallel to the rectifier output.

Advantages

The SE15FD-M3/I has many advantages, some of which include:

• Easy installation
• Protection against thermal and electrical overloading
• Capable of handling up to 400V
• High current rating
• Low conduction and switching losses

This diode package is an excellent choice for a range of power electronics applications, as it offers reliable performance, high efficiency, and easy installation. Furthermore, it is designed to dissipate heat effectively and protect itself against thermal and electrical overloads, making it a very safe and reliable device.

Conclusion

The SE15FD-M3/I is an excellent choice of rectifier package for a variety of applications. It is capable of handling heavy transients up to 400V and offers a range of advantages, including easy installation, high current rating, and thermal and electrical protections.
