DL4933-13-F: Overview

DL4933-13-F is a single rectifier diode, i.e. a diode that allows current to flow in one direction only. It is designed to be used in a wide range of applications as both a blocking and switching device. DL4933-13-F is a glass passivated chip with a plastic package, featured by its high surge current capability, high conductivity and low forward voltage drop.

Applications

DL4933-13-F is suitable for many medium- and large-scale power conversion applications, such as AC-DC converters, graphical power supplies, uninterruptible power supplies (UPS), switch mode power supplies, as well as inverters and motor controllers. DL4933-13-F is also used by OEMs for their end-products in the home appliance, industrial automation and automotive industries.

Operating Principle

The operating principle of DL4933-13-F is governed by the PN junction phenomenon. It is formed by the junction of a positively charged semiconductor and a negatively charged semiconductor. This creates a built-in, asymmetrical electric field. When the forward voltage is applied across the diode, the field pulls electrons from the negatively charged side to the positively charged side, creating a current that flows through the device. However, when the polarity of the voltage is reversed, the applied electric field is blocked, preventing any external current from flowing through the diode.

Technical Characteristics

DL4933-13-F has a nominal forward current rating of 1.3A and successfully withstands repetitive peak reverse voltage of 800V. The device is designed to be used in a wide range of temperature environment, with an operation range covering -55℃ to +125℃. Other technical features of DL4933-13-F include: low forward voltage drop (0.48V at 1.3A); a high surge current capability of 35A (peak and forward); short reverse recovery time of 0.2µs; and a recovery time of 5ns.

Conclusion

DL4933-13-F is a single rectifier diode ideal for a wide range of power conversion applications. It has a high surge current capability, low forward voltage drop, and is capable of operating in a wide range of temperature environment. The device is increasingly being used by OEMs for a number of applications in home appliance, industrial automation, and automotive industries. Furthermore, its PN junction operating principle makes it perfect for medium- and large-scale, AC-DC, graphical power supplies, uninterruptible power supplies, switch mode power supplies, as well as inverters and motor controllers.
