Introduction to RSFJL MHG Application Field and Working Principle

RSFJL MHG is a type of single phase rectifying diode commonly used in high frequency applications such as digital circuit power supply, switching power supply, UPS power supply, etc. As a component of electronic circuit, its role is to conduct the current in one direction but prohibit the current in the opposite direction.

RSFJL MHG Operating Characteristics

RSFJL MHG has the following operating characteristics: an average forward current of 0.2A and peak forward current of 1.0A. Its reverse voltage is 135V, and its maximum capacitor dissipation power is 40mW. In addition, its peak reverse surge current is 25A. Its total internal capacitance is 3.2pF, and its operating temperature range is - 40 ° C to 125 ° C.

RSFJL MHG Applications

RSFJL MHG is used extensively in high frequency switching circuits and other power conversion applications. It can be used as a rectifier diode in AC/DC power supply. For example, it can be used in the reverse load protection circuit of the DC power supply, which can protect the circuit from the reverse input AC power. It can also be used in the voltage stabilization circuit, which can raise the voltage level and make the voltage stable.

In addition, RSFJL MHG can be used in high frequency switching circuits such as switching power supply, digital control chip power supply or LED control system, so as to effectively convert AC voltage into DC voltage. Under the conditions of constant switching frequency, the current through RSFJL MHG does not lead to the increase of power dissipation, thus improving the power conversion efficiency.

Working Principle of RSFJL MHG

RSFJL MHG is made up of two semiconductor junction layers of opposite polarities. The anode side is connected to the positive end, and the cathode side is connected to the negative end. When the forward voltage is greater than the reverse voltage, the anode-cathode PN junction enters the conduction state. The current in this direction is called forward current, and the forward voltage is called forward voltage.

When the reverse voltage exceeds the breakdown voltage, the voltage and current of the diode will increase sharply, forming a negative spike. This abrupt increase in current is called surge current, and the breakdown voltage is called reverse breakdown voltage. When the forward voltage or reverse voltage exceeds the absolute maximum values, the operating temperature of the diode may rise, resulting in thermal damage.

Conclusion

RSFJL MHG is widely used in high frequency applications such as AC/DC power supply, switching power supply and digital control chip power supply. Its role is to conduct the current in one direction but prohibit the current in the opposite direction. Its working principle is that when the forward voltage is greater than the reverse voltage, the anode-cathode PN junction enters the conduction state, and when the reverse voltage exceeds the reverse breakdown voltage, the voltage and current of the diode will increase sharply, forming a negative spike.
