Introduction

Rectifier diodes arrays are used to provide efficient and cost-effective solutions for regulating electronic circuits by ensuring current flow in one direction only. The 1SS379 and LF rectifier diode arrays are widely employed in many modern electronic applications to protect delicate components and control circuit flows.

1SS379 Rectifier Diode.

The 1SS379 rectifier diode array is a single component, made up of four identical Schottky barrier diodes with an integrated resistor network, allowing it to pass high direct current while maintaining low resistance. The component features a very low forward voltage drop and an extremely low reverse leakage current, making it suitable for use in power supplies, and DC-DC converter applications.

1SS379 Application Field and Working Principle

The 1SS379 is used to protect electronic circuits and control electronic current flows. The component works by allowing current to flow from the anode to the cathode, but not in the reverse direction, ensuring that delicate components in the circuit are not damaged by backflow current. When a positive voltage is applied to the anode, electrons from the negative terminal flow to the anode, and then, due to the negative voltage of the cathode, the electrons flow away from the cathode, in the same direction as the positive voltage at the anode. This way, the current in each diode element flows in the same direction, allowing the current flow to remain stable. The integrated resistor network in the 1SS379 helps to reduce losses in the circuit, allowing current to be directed more efficiently and ensuring that the 1SS379 provides low forward voltage drop and low reverse current leakage. This helps to reduce power consumption and ensures reliable operation of the circuit. The 1SS379 is often used in systems that require high power handling, such as DC-DC converters, as its efficient current flow and low losses significantly reduce energy wastage and allow the system to operate reliably for longer.

LF Rectifier Diode

The LF rectifier diode array is a two element bridge rectifier, composed of a pair of Schottky diodes. The component has a low forward voltage drop, a high reverse breakdown voltage and a low reverse leakage current, making it suitable for numerous electronic applications.

LF Application Field and Working Principle

The LF is used to protect electronic components from current overloading and ensure stable current flows. The component works by allowing current to flow from the anode to the cathode, but preventing the flow in the reverse direction. The LF has a high reverse breakdown voltage, which helps to protect delicate components from reverse current flows. This is achieved by limiting the current to the maximum allowable rating without having to rely on the overvoltage protection provided by the anode-cathode junction. When a positive voltage is applied to the anode, electrons flow from the anode to the cathode through the duo of diodes. The low forward voltage drop of the LF means that the current flows with high efficiency and minimal losses. In addition, the LF also has a low reverse leakage current, which ensures that the current passing through the circuit is stable and that delicate components in the circuit are not damaged by backflow current. The LF is often used in power supplies and DC-DC converters, due to its efficient current flow and low losses, providing reliable power supply with minimal power consumption. The LF is also used in a wide range of other applications, such as automotive, telecom and aerospace systems.

Conclusion

In conclusion, the 1SS379 and LF rectifier diode arrays are efficient and cost-effective solutions for controlling electronic current flows, providing high current handling and reliably stable operation. The components feature low forward voltage drops and low reverse leakage currents, improving circuit performance, and significantly reducing power consumption. The two rectifier diodes arrays are suitable for a variety of electronic applications, including DC-DC converters, power supplies and automotive, telecom and aerospace systems.
