Introduction

The S3D-13 is a single-channel, full-wave rectifier with a three-terminal design. This diode operates in the avalanche mode, providing an efficient, low-voltage alternative to applications requiring a voltage regulator or voltage protection. The S3D-13 offers a high peak current capacity, low reverse leakage current, and low forward voltage drop, allowing it to be used in a variety of applications, including computer and telecom equipment, appliances, solar cell and lighting systems, and battery-powered systems.

Application Fields

The S3D-13 diode is ideal for applications requiring a low-loss, high-efficiency voltage rectifier. It can be used as the primary rectification stage for DC/DC converter applications, eliminating the need for a transformer or capacitor-isolated rectifier circuit. The S3D-13 is also suitable for in-circuit and stand-alone voltage regulation and surge protection.The S3D-13 is an ideal choice for powering CPU, motherboard, and SWAP applications in computer and telecom equipment. It is also well-suited for battery-powered applications, providing an efficient surge protection element as well as low-voltage, low-loss DC/DC rectification. Due to its low forward voltage drop and high peak current capacity, the S3D-13 can also be used in many solar cell, lighting, and appliance applications.

Working Principle

The S3D-13 is a three-terminal full-wave rectifier that employs avalanche breakdown technology and provides forward voltage drops as low as 0.6 V typically. This low voltage drop enables the device to provide efficient rectification, allowing it to be used in computer and telecom equipment, solar cells and lighting systems, and battery-powered systems.When an appropriate forward voltage is applied across the S3D-13’s anode and cathode terminals, a single, continuous avalanche breakdown occurs. This avalanche breakdown results in a fast switching action and stabilizes the forward conduction with a minimum of power dissipation.The S3D-13 is designed with a built-in reverse bias lockout feature, allowing it to protect against impulse transients. When the reverse voltage exceeds a certain threshold, the S3D-13 automatically turns off, preventing the leakage current from passing through the device and the associated circuit.

Conclusion

The S3D-13 diode provides an efficient and reliable solution for a number of applications. Its low forward voltage drop and high peak current capacity make it suitable for use as a DC/DC converter, as well as for in-circuit and stand-alone voltage regulation and impulse protection. The S3D-13 is an ideal choice for powering computer and telecom equipment, as well as solar cells, lighting systems, and battery-powered applications. Its three-terminal design ensures reliable operation, providing a low-loss, low-voltage alternative to applications that require voltage regulation or protection.
