Diodes - Rectifiers - Single - SF63GHA0G application field and working principle

The SF63GHA0G diode series is a single-terminal, low-saturation rectifier diode, which is designed and manufactured by the Sanyo Semiconductor Corporation. It is the ideal solution for switched mode power supplies, DC-DC converters, and motor control applications. The SF63GHA0G series rectifier diodes provide very low reverse leakage current, low forward voltage drop, and wide temperature ranges. Additionally, these diodes possess high surge capability and no short-duration reverse recovery.

Application Field

The SF63GHA0G diode series has wide application in power supply systems. It can be used in many different applications as a rectifier element. These applications include, but are not limited to: AC to DC converters, DC DC converters, motor control for robotics and automation, static converters, switching, rectifying and clamping circuits, transient voltage suppressors and fuses. The SF63GHA0G series is ideal for voltage regulation and clamping besides being used to produce rectified outputs from AC signals. It is suitable for a wide range of currents from 3A to 60A.

Working Principle

The SF63GHA0G diode series operates according to the PN junction diode principle. This kind of diode consists of two layers of semiconductor material, P-type and N-type, joined together to form a PN junction. When the PN junction is forward biased, the electrons are pushed towards the P-type side and holes are pushed towards the N-type side, creating a current across the two sides. When the PN junction is reverse biased, the holes and the electrons are kept away from each other, creating very little current across the two sides. This kind of device is ideal for use in rectifier applications, as well as for protection from transient voltages.

Performance Characteristics

The SF63GHA0G diode series provides low reverse leakage current, low forward voltage drop and wide operating temperature range from -40°C to +125°C. Additionally, these diodes possess high surge capability, meaning that they can sustain large inrush currents for short periods of time without getting damaged. The SF63GHA0G series rectifier diodes also have no short-duration reverse recovery, meaning that they remain in their off state until the voltage reaches its reverse recovery threshold. This is important for providing short switching times in electronic circuits.

Conclusion

The SF63GHA0G diode series is an ideal solution for applications in which a low-saturation rectifier is needed. It provides low reverse leakage current for improved efficiency, low forward voltage drop for reduced power losses, and wide temperature range for applications in extreme environments. In addition, its surge capability and lack of reverse recovery time make it suitable for use in many applications, from voltage regulation and clamping to switching, rectifying and clamping circuits.
