ES3B is a high-precision, low-voltage, low-power rectifier diode with high stability and high reliability. It\'s a device used to convert AC voltage into DC, or to limit and control the voltage oscillation. Its working principles are based on the rectifier effect, which means the power flow is always from anode to cathode. The ES3B can withstand voltage up to 74V and current up to 3A. It is mainly used in power supplies, light fixtures and other device requiring electrical polarity control.It has a very low forward voltage which makes it suitable for use in high-precision control systems. The small size makes it very suitable for use in small and narrow spaces. In addition, it is also suitable for applications where the power level is not very high. In operation, the ES3B rectifier passes the current through a single rectifier circuit consisting of a diode, a capacitor, and a resistor. The diode is responsible for generating the current flow between the two opposite terminals, while the capacitor connected in parallel can reduce the reactance and also adjusts the capacitance. The resistor is also connected in series, which allows for efficient control of the amplitude of the AC current.During the positive half-cycle, the current flow is between the anode and cathode, and a reverse-voltage protection is provided by the capacitor. When the AC current is applied to the diode, it turns the diode on and passes the current through the circuit. The capacitor starts to charge and reduces the voltage between the anode and cathode. When the AC current drops down to negative value, the diode conducts and the retroactive voltage is blocked by the capacitor. The main benefit of using the ES3B rectifier is how well it can handle high input voltages and currents without taking up too much space. This makes it ideal for applications that require a high precision, low voltage, and low power operation where space is limited. It also provides excellent protection against voltage spikes, which improves its overall reliability. Overall, the ES3B rectifier is an excellent choice for applications where power levels are not very high, space is limited, and the goal is to maintain a stable voltage. Its low forward voltage and efficiency allow it to handle high input voltages and currents efficiently and reliably. Its small size makes it well suited for use in small and narrow spaces, and when combined with its reverse-voltage protection feature, it provides superior reliability and performance.
