Introduction: The SE20PDHM3/84A is a single rectifier diode. It is manufactured by STMicroelectronics, one of the leading semiconductor companies on the market. This diode is intended mainly for general-purpose high-efficiency applications, both DC and AC. The diode has an 80V maximum reverse voltage and a maximum forward current of 54A.

Application Field: The SE20PDHM3/84A can be used in many types of applications, such as for power factor correction, rectification, snubbing, overvoltage protection, applicator instruments, and voltage switching. This diode is particularly suitable for automotive, industrial and consumer endurance applications due to its high efficiency, fast switching, and low power dissipation. It can also be used in solar inverters, automotive chargers, refueling systems, and power supplies.

Working Principle: The SE20PDHM3/84A works by using a PN-junction, which acts as a rectifier. The junction allows current to flow in one direction, while blocking the opposite direction. The forward voltage drop across the rectifier corresponds to the energy lost in the conversion process. This is usually a small amount, usually in the range of 0.2-0.4 volts. The junction also features a reverse breakdown voltage, which varies depending on the specific application. When the applied voltage exceeds the breakdown voltage, current flows in the reverse direction.

Conclusion: The SE20PDHM3/84A is a single rectifier diode that is suitable for many different applications. It features an 80V maximum reverse voltage and 54A maximum forward current. It is intended mainly for general-purpose applications, both DC and AC. The working principle of the SE20PDHM3/84A is based on a PN-junction rectifier, which allows current to flow in one direction while blocking the opposite direction. The junction also has a reverse breakdown voltage that varies depending on the application. In conclusion, the SE20PDHM3/84A is a useful and efficient diode for many purposes.
