Working Principle of FR103G R1G

The FR103G R1G diode is a single-phase, glass-passivated junction rectifier that is designed to handle high currents and temperatures. The device firmly rectifies the alternating current (AC) into direct current (DC) with minimal losses. A diode’s working principle relies on the junction region, which acts as an electrical barrier between the two p-type and n-type semiconductor materials. When direct current is applied to this junction region, it behaves as an insulator and prevents the current from flowing in the reverse direction. However, when alternating current is applied to this junction region, the junction region behaves like a conductor and allows the current to flow.

The FR103G R1G diode is capable of handling currents up to 10 A, with a voltage rating of up to 1000 V. Its excellent thermal stability and wide operating temperature range make it well suited for industrial applications that require temperature robustness. Additionally, its low forward voltage drop, low reverse leakage current, and low junction capacitance allow the device to operate at high frequencies, making it perfect for applications where fast switching is necessary.

Conclusion

The FR103G R1G diode is a high-quality, single-phase rectifier designed for use in high-temperature applications. Its excellent thermal stability, wide operating temperature range, low forward voltage drop and low junction capacitance make it ideal for use in power supplies, motor speed control and lighting dimmers. Additionally, its ultra-low reverse leakage current and low capacitance allow it to be used in DC-DC converters, where a high level of performance is required.
