Diodes – Rectifiers – Single

The SJPJ-H3VL rectifier diode is one of the common and widely used diodes in the world today. It is a silicon diode with a built-in bridge rectifier circuit and is used for low- frequency applications. The SJPJ-H3VL rectifier diode is ideal for producing a stable DC voltage from a mains AC voltage supply and is used for a wide range of applications.

Application Field

The SJPJ-H3VL rectifier diode is popularly used in DC power supplies, in AC/DC converters, in AC/DC motor speed controllers, in audio equipment, in industrial equipment, and in any application where a stable DC voltage is needed. It is also used as a rectifier diode in AC/DC rectification circuits, and it is used as a rectifier switch in circuit protection applications.

Working Principle

The SJPJ-H3VL rectifier diode’s working principle involves a bridge rectification circuit that is included on the chip. The bridge rectification circuit is composed of four diodes which are connected in series to form a bridge. The AC input voltage is applied to the bridge rectification circuit, and when a positive half-cycle of the AC voltage is applied, the two middle diodes are forward biased and the two other diodes are reversed biased. This allows the current to flow through the two forward biased diodes only, resulting in rectification of the AC input voltage. The output of the bridge rectification circuit, which is the DC voltage, is then applied to the load.

In addition to the bridge rectification circuit, the SJPJ-H3VL rectifier diode also includes components such as a thyristor and an Insulated Gate Bipolar Transistor (IGBT). The thyristor is used to provide voltage isolation and protection from voltage transients, while the IGBT is used for switching off the device when it is not in use.

Conclusion

The SJPJ-H3VL is a rectifier diode that is widely used in low-frequency applications where a stable DC voltage is required. It is ideal for applications such as DC power supplies, AC/DC converters, AC/DC motor speed controllers, audio equipment, and industrial equipment. The rectifier diode includes a bridge rectification circuit and includes components such as a thyristor and an IGBT to provide voltage isolation and protection from voltage transients.
