Diodes - Rectifiers - Single

The S30640 rectifier diode is a component that is most commonly used in the electronic and electrical industry. It is a three-terminal component and is available in two different packages, including standard DO−41 and SMA packages. The S30640 is a high voltage, fast rectifier diode, which is capable of dissipating up to 1.50 watt.

Application Field

The S30640 is primarily used as a rectifier in a variety of applications, including high voltage and high current circuits, such as AC/DC converters and power supplies. It is also used to protect sensitive equipment from voltage and current fluctuations, as well as to equalize the voltage distribution across a circuit. Other applications of the S30640 include overvoltage protection in automotive, lighting and telecommunication systems, and electromagnetic interference protection.

Working Principle

The S30640 rectifier diode works by allowing the current to flow in one direction only − from the anode to the cathode. The anode acts as a positive terminal and the cathode acts as a negative terminal. When the anode to the cathode is positive, the current flow is through the diode and the diode is said to be forward biased. In this state, the diode will drop a forward voltage and allow the current to flow. Conversely, when the anode to the cathode is negative, the current flow is blocked and the diode is said to be reverse biased. In this state, the diode will block the current, preventing it from flowing.

The current through the S30640 is limited by its rated maximum current. This value will determine the amount of current that can be passed through the diode. Higher values are generally used for applications where higher-power devices are connected, such as those which require higher amounts of current. The Voltage Drop of the S30640 is also slightly higher than other rectifier diodes due to its higher forward voltage rating.

The S30640 also features a high surge tolerance and low junction capacitance, making it ideal for applications requiring high surge protection. Additionally, it has a high stability rating, allowing it to withstand temperature variations and fluctuations in ambient temperature.

In terms of safety, the S30640 is compliant with both the Restriction of Hazardous Substances (RoHS) directive and the European Union Energy-related Product (ErP) directive. This ensures that the component is safe for use in any electronic product.

Conclusion

The S30640 is a high voltage rectifier diode that is used primarily for protecting sensitive equipment from voltage and current fluctuations, equalizing voltage distribution across a circuit, and providing overvoltage protection in various applications. It is a three-terminal component, available in standard DO−41 and SMA packages, and is capable of dissipating up to 1.50 watt. It is also compliant with both RoHS and ErP directives, ensuring its safety for use in electronic products.
