CDSOT236-T24 Application Field and Working Principle

TVS Diodes are a type of semiconductor used to protect electrical and electronic equipment from transient electrical surges or spikes in voltage. The CDSOT236-T24 is a low cost, dual-channel, low capacitance, electro-static discharge (ESD) protection diode. This particular type of diode is designed specifically for high density ESD protection applications in consumer electronics products, such as mobile phones, tablets, and mobile USB interfaces. In this article, we will discuss the application field and working principle of the CDSOT236-T24.

Application Field

The CDSOT236-T24 has a low capacitance of only 0.16 pF in each channel, making it ideal for very high density ESD protection applications. As a result, it is widely used in a variety of consumer electronic devices, such as mobile phones, tablets, and mobile USB interfaces. It is also suitable for other applications, such as set-top boxes, DVD players, digital cameras, and PDAs. In addition, it is well suited for applications where low capacitance and high durability are desired, such as in automotive products.

Working Principle

The working principle of the CDSOT236-T24 is based on a Zener diode structure. A Zener diode is a diode that breaks down when the reverse voltage across the diode exceeds a predetermined level. The CDSOT236-T24 is designed so that it can break down when exposed to an ESD pulse of up to 4kV. In this way, it can protect the connected device against electrical surges and spikes.

When an ESD pulse is applied, the CDSOT236-T24 acts as a Zener diode and breaks down, clamping the voltage across its terminals to a predefined level. This clamps down the voltage and prevents it from damaging the connected electronic device. After the pulse has passed, the CDSOT236-T24 recovers and returns to its normal, off-state.

Conclusion

In conclusion, the CDSOT236-T24 is a low cost dual-channel electro-static discharge protection diode designed for high density ESD protection applications. It has a low capacitance of only 0.16 pF in each channel, making it ideal for consumer electronics products, such as mobile phones, tablets, and mobile USB interfaces. The CDSOT236-T24 is based on a Zener diode structure, and works by clamping the voltage across its terminals to a predefined level when exposed to an ESD pulse, thus protecting the connected device.
