Diodes - Rectifiers - Single: S25GR Application Field and Working Principle

The S25GR Diode rectifier is a single diode rectifier with a reverse recovery time of 200ns. It is a general-purpose silicon rectifier and is widely used in many applications such as full-wave rectification, motor control, and power electronic lighting systems. S25GR is designed to provide an economical and reliable method of rectifying the power frequency AC voltage in consumer and industrial power supplies.

Features and Benefits of S25GR

The S25GR provides a number of unique features. This includes low forward volt drop, fast switching times (200ns), low leakage current, and a high surge-current capability. It\'s low-forward volt drop reduces switching losses in the converter AC-DC converters while its fast switching times ensure that the rectifier can respond quickly to step changes in the input voltage. The low leakage current and surge-current capability provide reliable and safe operation in a wide range of applications.

Applications for S25GR

S25GR is used in a wide range of applications, including motor control, power electronic lighting systems, power supplies, and other current and voltage converters. It can be used in single-phase and three-phase motor control, including AC-DC and DC-AC converters. It can also be used in a wide range of industrial electronics and consumer electronic circuits, such as home appliances, telecommunications, and automotive systems. In power supplies, S25GR provides a fast and reliable rectification technique for AC voltage.

Working Principle of S25GR

The S25GR diode rectifier works by taking AC voltage and rectifying it into DC voltage. The device consists of two diodes connected in antiphase, effectively creating a full-wave rectification circuit. On the positive half of the AC wave, the forward biased diode conducts and the reverse biased diode blocks the current flow. On the negative half of the wave, the reverse biased diode conducts and the forward biased diode blocks the current flow. When AC voltage is applied to the diode, current flows through one diode and not the other. This allows the circuit to effectively convert alternating current into direct current.

Conclusion

The S25GR Diode rectifier is an economical and reliable way to rectify AC voltage. The device features a low forward volt drop, fast switching times, low leakage current and a high surge-current capability. It can be used in a wide range of applications, including motor control, power electronic lighting systems, power supplies, and other current and voltage converters. This makes the S25GR a versatile and reliable diode rectifier.
