Diodes – Rectifiers – Single

The SD840-B is one of the most versatile and dependable Single Diode Rectifier (SDR) components in the electronics market today. By utilizing state-of-the-art production technology, the SD840-B offers designers numerous advantages compared to competing products. Its compact size, low power consumption and wide temperature operating range makes it an ideal choice for most applications.

The SD840-B is capable of withstanding up to 1 Amp forward constant current and can be used in both DC and AC applications. It features a maximum reverse voltage rating of 400V, making it suitable for a wide range of design needs. The wide operating temperature range of the SD840-B allows it to be used in even the most extreme environments.

The SD840-B’s application field is wide and varied. It can be used as a rectifier in DC/AC power supply systems, power systems of electrical devices, a DC/DC converter, or to build voltage regulators. It can also be used in various light applications, including automotive lighting systems, traffic lights, and illuminating street signs. It can also be used in electrical energy storage systems.

The working principle of the SD840-B is quite simple. When an electrical charge is applied to the circuit, the current flows through the anode and cathode of the diode. The anode voltage is always one volt higher than the cathode voltage due to the anode’s higher potential and the diode’s built-in resistance. The current only runs one way, though the diode and is known as the forward bias. When the current hits the cathode and the reverse bias is increased, the diode will become reverse- biased and no current will flow. This is known as the blocking effect.

The SD840-B also features a temperature-proof encapsulation that protects the device from heat and water, which increases its durability and reliability. Additionally, its double Schottky barrier structure provides improved reverse recovery, making it suitable for high-frequency circuits. This device also offers high inrush surge current capability, making it ideal for use in switching regulator circuits.

In short, the SD840-B is a reliable and dependable single diode rectifier that can be used in numerous applications and environments. Its low power consumption and wide operating temperature range combined with its highly durable, robust design make it an ideal choice for most applications. The simple working principle and temperature-proof encapsulation also make it a reliable and long-lasting product.
