Single rectifier diodes are frequently used in electronics to convert alternating current (AC) to direct current (DC). The FGP20BHE3/73 is an example of this type of diode with a 3 Amp (A) average forward current rating and 200 volts (V) repetitive peak reverse voltage rating. This diode is suitable for many applications, ranging from switch mode power supplies to consumer electronics. This article will discuss the FGP20BHE3/73 application field and working principle.

Application Field

The primary applications for the FGP20BHE3/73 diode are in switch mode power supplies and other places where a high forward current rating is required. It can be used in low power hot swap circuit systems, such as those found in computer network routers, to protect the circuit from inadvertent damage. The diode is also suitable for LED display power supply design and other consumer electronics. In addition, it can be used for radio frequency (RF) power amplifier design, as well as for filtering and rectifying power signals.

Working Principle

Rectifier diodes such as the FGP20BHE3/73 function by allowing current to flow in only one direction. This is accomplished by the diode’s PN junction, which is created by doping the diode’s semiconductor material. This doping forces the current to flow in the same direction, creating an asymmetric voltage drop across the device. When AC voltage is applied to the diode, the positive cycles of the wave are free to flow across the diode’s junction, but the negative cycles are blocked. This causes the diode to effectively change the AC input into DC output.

The FGP20BHE3/73 has a 3 A average forward current rating and a repetitive peak reverse voltage rating of 200 V. This means that the diode is suitable for use in circuits with up to 3 A of current and 200 V of alternating current. The diode’s junction capacitance is also important to consider, as it affects how quickly the diode can respond to changing voltages. The higher the junction capacitance, the lower the diode’s response time.

Conclusion

The FGP20BHE3/73 single rectifier diode is an ideal choice for a variety of applications, such as switch mode power supplies, LED display power supply design, and RF power amplifier design. The device’s 3 A average forward current rating and 200 V repetitive peak reverse voltage rating make it suitable for a wide range of low power hot swap circuit systems and other circuitry. Additionally, its junction capacitance can affect its response time, which is important to consider when designing a circuit.
