This component is part of the Bridge Rectifier series manufactured by STMicroelectronics and operates in the -40°C to +125°C ambient temperature range. This component has an avalanche voltage V_A of 150V, a forward voltage drop V_F of 1.1V and a junction temperature of T_j of 175°C.

Application Fields

The EGD20DHE3/73 is well suited for general purpose applications such as low-voltage power supplies, DC-DC converters and on-board charging circuits. This device is also suitable for consumer, industrial, automotive and telecommunications applications. Furthermore, the EGP20DHE3/73 is particularly used for UPS areal power supply, solar energy storage power supplies and metering electronics.

Working Principle

The EGP20DHE3/73 is comprised of four high-reliability diodes connected in a bridge configuration. It acts as a full-wave rectifier meaning it converts alternating current into direct current. When the source voltage of the AC voltage is positive, it passes through the diode D1 and then to the load. Conversely, when the source voltage is negative, it passes through the diode D2 in reverse bias and then to the load.

It is worth mentioning that diodes always conduct electricity in one direction only and the amount of current that flows through them is regulated by a resistor or a capacitor. The capacitors act as filters in the full-wave rectifiers and helps to smooth out the pulse from the rectified waveform to enable a steady DC output. In addition to this, it also reduces the amount of voltage ripple.

Conclusion

To conclude, the EGD20DHE3/73 is classified as a single-phase, full-wave bridge rectifier with a peak repetitive reverse voltage of 73V and a maximum average forward current rating of 15A. This component is suitable for general purpose, consumer, industrial, automotive and telecommunications applications and provides the advantage of full wave rectification with a low voltage ripple. The resistor or capacitor filter acts to provide a steady DC output with reduced voltage ripple.
