SL43HE3/9AT

Application Field

The SL43HE3/9AT is a highly efficient, rugged and reliable single-phase full-wave silicon rectifier. It is widely used in a variety of power applications including power rectifiers and electronic projects. The device is suitable for use in light, medium and heavy-duty applications, where efficiency and reliability are of paramount importance.

Working Principle

The SL43HE3/9AT consists of four high-power rectifier diodes that are connected in a full-wave bridge configuration. The device operates in a symmetrical manner to rectify both positive and negative half-cycles of the alternating current waveform, which allows the device to produce a stable and consistent direct current output. The entire device is encapsulated in a hermetically sealed package to protect it from external environmental factors and ensure that the output waveforms remain stable under a wide range of operating conditions.

The diode bridge rectifier works by allowing current to flow through only one direction at a given time. When the input voltage waveform rises above the zero line, the two top diodes in the bridge are forward biased, allowing the current to flow across the bridge from the anode to the cathode. When the waveform falls bellow the zero line, the bottom two diodes of the bridge become forward biased, allowing the current to again flow from the anode to the cathode. This process repeats itself every half-cycle, resulting in an output waveform that is a perfect reproduction of the input waveform but with a positive direct current offset. The resulting DC output from the device is very consistent and can be used for a variety of applications such as powering electronic circuits.

Conclusion

The SL43HE3/9AT by STMicroelectronics is a highly efficient single-phase full-wave rectifier suitable for a wide range of power applications. The device features four diodes that are connected in a full-wave bridge configuration, which allows the device to produce an output waveform which is a perfect replica of its input but with a positive direct current offset.
