Diodes are widely used in electrical engineering as semiconductor rectifier components that can rectify alternating currents into direct currents. Generally, diodes are divided into two major categories according to the number of their electrodes: single diodes and double diodes. The single diode includes RL103-N-2-1-BP. This article will focus on the application field and working principle of RL103-N-2-1-BP.

RL103-N-2-1-BP Application Field

The RL103-N-2-1-BP diode is a kind of single rectifier diode which consists of PN junctions. This device has high-efficiency power rectification and excellent surge resistance. Generally, it is mainly applied in various kinds of lighting systems, such as allowing night vision, brand-lighting, and backlight modulating. With fine heat dissipation and stable performance, it is also widely used in LED lighting and LED spotlight. The RL103-N-2-1-BP diode is particularly suitable for the driven power of high output power LED. In addition, it is also suitable for TV power supply, charger rectifier, high-power output galvanometer driver as well as multi-harmonic filter.

RL103-N-2-1-BP Working Principle

The RL103-N-2-1-BP single diode consists of a PN junction. It is constructed from a N-type semiconductor substrate and a P-type semiconductor layer. The N-type semiconductor substrate is a substrate through which electrons can move freely, and the P-type semiconductor layer is a substrate through which holes can move freely. When a voltage is applied, the current direction is reversed for the diode is a one-way conductor. The conduction effect exists on a low forward voltage (Vf) and disappears on a high forward voltage (Vf). The peak inverse voltage (PIV) defines the maximum allowable reverse voltage. Moreover, the RL103-N-2-1-BP single diode also has an anode and a cathode. When the anode is connected to the positive end of the power supply and the anode is connected to the negative end of the power supply, the diode will be in the on state, and vice versa. This is a basic way of controlling the flow of electric current.

The RL103-N-2-1-BP single diode is also featured by its low operating temperature (25 °C) and temperature coefficient (0.7-1.1mV / °C). The diode is designed to provide fast response and excellent surge resistance up to 20A which can ensure high efficiency power rectification. In addition, its cathode output falling edge time is 1.33us and its cathode output rising edge time is 1.77us.

Conclusion

The RL103-N-2-1-BP is a single rectifier diode which consists of PN junctions. It is mainly used for various kinds of lighting system, LED drive, TV power, charger rectifier and multi-harmonic filter. With high efficiency power rectification, fine heat dissipation, stable performance, and fast response, the RL103-N-2-1-BP diode is an ideal choice for modern electrical engineering.
