TVS diodes, also known as Transient Voltage Suppressors and Varistors, are used to protect circuits from electrical overvoltages or overcurrents. The VDRS05C230BSE is a typical member of this family, and one which is widely used for various applications. In this article, we\'ll discuss the application field and working principle of this TVS diode.

Application Field

The VDRS05C230BSE is a bidirectional TVS diode, and is designed to absorb transient voltage spikes in medium and low voltage applications. It features a low capacitance of 5pF, which makes it suitable for applications where high frequency noise needs to be filtered. This TVS diode can clamp transient voltage spikes up to 70V in peak pulse power of 2000W for 8/20 microseconds. It can stand up to 150V of continuous working voltage in normal operation.

The VDRS05C230BSE is designed for use in low voltage and current applications such as mobile phones, digital cameras, portable computers, and general electronic components. It can also be used in high-frequency circuits such as RF modules, and in circuits with high temperature environments, such as automotive and industrial applications.

Working Principle

The basic principle of the VDRS05C230BSE is as follows: when it is subjected to an overvoltage, its internal resistance increases. This increases the power dissipation which in turn gets dissipated as heat. Because of this, it acts as a clamp for the overvoltage, diverting it from the circuit and protecting it from damage. This makes the diode suitable for use in protection of various electrical components from damage due to overvoltage.

The VDRS05C230BSE also has a high ESD (Electrostatic Discharge) protection capability. This is due to its wide operating voltage range and its high capacitance, which improves its performance in filtering high frequency transients. The diode is also designed for low-current applications, which makes it optimal for use in various types of microcontroller applications.

In summary, the VDRS05C230BSE is a bidirectional TVS diode designed to protect against overvoltage and ESD in various applications. Its high capacitance makes it suitable for use in high-frequency circuits, while its low capacitance protects against low-frequency transients. Due to its low current operation, it is also suitable for use in many types of microcontroller applications.
