Diodes - Rectifiers - Single

S2D13-F is a single-phase rectifier module, which includes two S2D13-F rectifier and one thermistor for over-temperature protection. This small and compact module is optimized for use in small power applications like PC power supplies, DC/DC converters, rechargeable battery chargers, solar power systems and other high efficiency applications where current > 1A. It features zero reverse recovery current, reverse voltage protection, and fast turn-on time.

Application Field

The S2D13-F is an ideal rectifier for applications that require current up to 1A without compromising on performance or reliability. It is also suitable for use in many telecommunications applications where current and temperature must be managed tightly. Apart from that, the S2D13-F is also well suited for automotive applications, where fast turn-on times are highly desirable.

The S2D13-F offers a trade-off between minimal power dissipation and fast switching speed, making it suitable for a variety of applications. It can be used as a power rectifier for power supplies, as a current limiter for inrush current protection, or as an AC/DC rectifier for DC/DC converters. Additionally, the S2D13-F can also be used as a bridge in combination with other diodes for a variety of other applications.

Working Principle

The S2D13-F single-phase rectifier module is equipped with a pair of S2D13-F diodes, which are reverse connected and offer a low forward voltage drop. In order to provide a stable output voltage, each of the two diodes is driven with a dedicated rectifying circuit. This ensures that the current flows both ways in each diode, while the two diodes are synchronized with each other. This results in a low voltage drop and fast turn-on time.

The S2D13-F rectifier module also features a thermistor for over-temperature protection. This thermistor monitors the temperature at the rectifier module and acts as a Constant-Current Limiting (CCL) device when the temperature rises too high. Once the temperature reaches a certain value, the thermistor will reduce the current current, thus preventing further temperature rises.

Finally, the S2D13-F rectifier also features a reverse voltage protection, which prevents the diode from conducting in reverse and damaging the rectifier module. This is especially important in sensitive applications like power supplies or DC/DC converters, as the diode would otherwise need to be manually disconnected in order to prevent the module from the damage.

Conclusion

In conclusion, the S2D13-F single-phase rectifier module is an ideal solution for small power applications such as PC power supplies, DC/DC converters, rechargeable battery chargers, solar power systems and other high efficiency applications. It offers excellent performance and reliability, and features a thermistor for over-temperature protection, a reverse voltage protection and fast switching speed. Therefore, it is an ideal choice for a wide variety of applications.
