SE20PGHM3/85A is a four-phase bridge rectifier that is used to rectify currents in power supplies and other applications. Its rectification efficiency is high, and the third-harmonic suppression effect is excellent. Generally, it is installed in enclosed cabinets, and its excellent cooling characteristics enable it to work even in radial ambient temperatures up to 85 degrees Celsius.

The SE20PGHM3/85A has four rectifying controllable diodes that are connected in a bridge form, including two main thyristors and two antiparallel diodes. When positive and negative half waves appear on two of the anodes and two of the cathodes, the thyristors conduct and the antiparallel diodes are reversed connected. The peak voltage across the device can be up to 1600V and the maximum current output depends on the ambient temperature.

The application of SE20PGHM3/85A lies in the rectification of power supply voltage. By rectifying AC (alternating current) supply voltage into DC (direct current), it can drive the power circuit to carry out certain functions. Additionally, this rectifier can also be used in wide-area monitor systems, telecom power systems, industrial power systems, and solar energy systems. With its high temperature resistance and excellent cooling characteristics, this device is reliable and durable.

The working principle of SE20PGHM3/85A involves the operation of its four rectifying controllable diodes. Two anodes and two cathodes are left floating, and one anode and cathode are connected to the AC power input, the other two the DC output. When the voltage across the two input nodes change polarity, the two diagonal thyristors will conduct current and the two antiparallel diodes are driven into reverse connection. Therefore, the current is successfully rectified and blocks the direct current, while allowing the alternating current to flow through.

The SE20PGHM3/85A is an ideal choice when it comes to rectifying power supply voltage and supplying the power circuit with DC current. It can work stably in harsh environments with its excellent cooling characteristics, and it is reliable, durable and cost-effective. Therefore, this product is widely used for a variety of applications, such as wide-area monitor systems, telecom power systems, industrial power systems, and solar energy systems.
