TVS - Diodes: CPDT-24V Application Field and Working Principle

A TVS - diodes or transient voltage suppressor diode is a high-speed, high-power member of the semiconductor diode family which is specifically designed to protect electronic circuits from damaging transients such as electromagnetic interference, or voltage spikes.The CPDT-24V is a fast-acting, dual-stage 24-volt bidirectional TVS diode. It can be used in circuits that require protection from transients caused by switching circuitry such as in automotive or industrial systems. The device features a junction-to-cathode breakdown voltage of 24V, maximum peak pulse current rating of 80A, and an adjustable clamping voltage between 20V and 24V.

CPDT-24V Application Field

The CPDT-24V is suitable for a wide range of applications, including automotive and industrial systems where transients resulting from switching circuits are present. It is ideal for use in data lines and power lines, as well as sensitive electronic equipment. This device can be used to protect power/data port circuits, as well as automotive sensors and other electronic components that need protection from transients.

CPDT-24V Working Principle

The CPDT-24V utilizes a combination of two protection devices, the polymer diode and the avalanche diode, to provide both low-level transient protection and high-level overvoltage protection. The polymer diode, also known as the TVS diode, acts as a v-shaped voltage clamp, limiting the transient voltage to a predetermined level.The avalanche diode is triggered when the transient exceeds the voltage level of the polymer diode. This results in a rapid breakdown of the junction, redirecting the transient to ground and limiting it to a safe voltage. This action provides fast, effective protection for a wide variety of electronics, including automotive applications.

Conclusion

The CPDT-24V is a bidirectional, fast-acting TVS diode featuring a junction-to-cathode breakdown voltage of 24V and an adjustable clamping voltage between 20V and 24V. It can be used in a wide range of applications, including automotive and industrial circuits, to provide protection from transients resulting from switching circuits. It utilizes a combination of the polymer diode and the avalanche diode to provide both low-level transient protection and high-level overvoltage protection, making it an effective tool to safeguard sensitive electronic equipment.
