Diodes - Rectifiers - Single

SD2114S040S5R0 is a single rectifier diode. It is a low-forward-voltage diode that consists of a chip, an anode, a cathode and a metallurgic lead-frame. Its features include low-turn-on voltage and high forward surge capability.

Application Field

SD2114S040S5R0 is widely used in power supplies, DC power converting, electronic Fuses and LED lighting applications. It can be used for bridge full-wave rectification, free-wheel protection in DC power converting systems, and a control switch in battery-management systems. This rectifier diode can also act as a fast-acting AC clamp in electronic Fuses and a rectification diode in LED lighting applications.

Working Principle

When the voltage applied across the anode and cathode is above a certain level, SD2114S040S5R0 acts as an open circuit, allowing an electric current to pass up to its maximum operating current limit, however, when the voltage drops below a certain level, it acts as a closed circuit, stopping current flow. The peak inverse voltage (PIV) rating of this diode should not be exceeded.

SD2114S040S5R0 has a junction-mounted die enclosed in a plastic package which ensures low-forward voltage drop, low-leakage current, high thermal cycling performance, and fast switching. In single rectifier applications, this diode is an ideal choice to provide protection against influx of negative voltages.

In forward conduction mode, this rectifier has high surge capability, low-turn-on voltage, high-current levels and low power dissipation, thus allowing for higher power output and improved efficiency.
