The SS8P3LHM3/87A from Advanced Semiconductor is a single-phase, 400V, 8.3A full-wave bridge rectifier. This device features a low forward voltage drop, high reverse energy capacity, low reverse leakage current, and fast recovery time. As such, it is a great choice when high power efficiency and reliability are key requirements.

Application Fields

The SS8P3LHM3/87A is perfect for general-purpose AC-to-DC rectification in appliances, power supplies, or other engineering designs that require efficient and reliable power conversion. This device is also well suited for powering AC-DC switching power supplies, low-voltage lighting, and high-voltage applications in the automotive, industrial, and consumer markets.

Overview of Working Principles

The SS8P3LHM3/87A is a full-wave bridge rectifier, meaning that it rectifies an AC waveform into a DC waveform by coupling four diodes in a series loop in a way that allows both the positive and negative portions of the waveform to be rectified. It is a bridge rectifier because it is composed of four diodes arranged into two head-to-tail branches across the two terminals. In order to accomplish this, each diode must allow current to flow in one direction and block current from flowing in the other while maintaining low forward voltage drop and high reverse energy capacity.

Forward Voltage Drop and Reverse Voltage Recovery

The forward voltage drop of the SS8P3LHM3/87A is typically around 0.7 V at 8.3A and its reverse voltage recovery time is also low. This is vital for efficient and reliable power conversion, as a low forward voltage drop reduces power loss and a low reverse voltage recovery time ensures that the power converter does not waste time switching between conducting and blocking states.

Reverse Leakage Current

The reverse leakage current of the SS8P3LHM3/87A is also low and helps ensure high efficiency. Reverse leakage current is the current that flows in the reverse direction when the forward current is blocked, and it can be significant and cause power loss. By keeping the reverse leakage current as low as possible, the SS8P3LHM3/87A is able to offer the most efficient power conversion possible.

Conclusion

The SS8P3LHM3/87A from Advanced Semiconductor is a single-phase, 400V, 8.3A full-wave bridge rectifier. This device is a great choice for AC-to-DC power conversion as it boasts a low forward voltage drop, fast recovery time, and low reverse leakage current. With these features, the SS8P3LHM3/87A is able to provide efficient and reliable power conversion for a wide range of applications.
