Working Principle

The working principle of the SB140A-E3/73 rectifier is based on the properties of PN junctions. PN junctions are formed when two different types of silicon, such as N-type and P-type, are brought into contact with each other. When a voltage is applied, electrons and holes are generated at the junction. Electrons move from the N-type silicon to the P-type silicon, and holes move from the P-type to the N-type silicon. This movement of charge creates a region of electrical neutrality and leads to the formation of the PN junction.

The SB140A-E3/73 then uses this junction to form a full-wave rectifier circuit. When an AC voltage is applied to the rectifier, the PN junction will switch the current on and off in accordance with the polarity of the voltage. This allows the rectifier to convert alternating current to direct current by allowing current to flow in one direction only.

Conclusion

The SB140A-E3/73 is a silicon rectifier that is used in a variety of applications. Its maximum junction temperature is 175°C and its maximum reverse voltage is 800 volts. The SB140A-E3/73 utilizes a PN junction to form a full-wave rectifier circuit, which converts alternating current to direct current. This is an effective and reliable component that is suitable for a range of applications.
