TVS - Diodes

A transient voltage suppression diode, or TVS diode, is an electronic component used to protect other components in a circuit from the effects of voltage spikes, which can be caused by lightning, electrostatic discharge, or fluctuations in the local alternate current. The CDNBS16-T36C is a TVS diode specifically designed for medium level power supplier or household electronic circuits, such as computers, TV sets, and cell phones. In this article, we will discuss the application field and working principle of the CDNBS16-T36C.

Application Field

The CDNBS16-T36C is specially designed for medium power supplier or household electronic circuit application due to its thin, flat contour where a large how-power transformer can be present. It utilizes two layers of aluminium oxide to provide a better uniform breakdown voltage, and its integrated surge-current absorption capability is enhanced with a unique bond wire bridge design. Its dielectric strength is increased with a slimmer physical profile, allowing the CDNBS16-T36C to fit in tight spaces. Due to its optimized thermal resistance, the CDNBS16-T36C can handle high surge currents with a minimum operating temperature rise.

Working Principle

The CDNBS16-T36C is designed to protect other components in a circuit from voltage spikes by clamping the voltage to a safe level. When a high voltage surge occurs, the TVS diode is activated, allowing a current to flow, but preventing the voltage from exceeding the voltage rating of the TVS diode. The TVS diode has two metal layers: a cathode and an anode. The cathode is connected to ground, while the anode is connected to the voltage source. When a surge occurs, the current is redirected through the TVS diode instead of the protected component, and the voltage is clamped to the voltage rating of the TVS diode.

In operation, the CDNBS16-T36C works in two distinct modes: avalanche breakdown and temperature-sensitive. In the avalanche breakdown mode, the diode is designed to respond quickly to high voltage spikes, eliminating them before they can damage the protected component. In the temperature-sensitive mode, the diode can be designed to reverse bias and lower its voltage tolerance as temperatures increase. This feature allows the diode to provide a more consistent level of protection for the protected component in more demanding environments.

The CDNBS16-T36C also provides improved safety protection due to its integrated internal isolation barrier. This barrier isolates the protected component from any negative voltage spikes, protecting it from electrical shock or short circuits. Moreover, the thermal resistance of the CDNBS16-T36C allows for better cooling and provides for higher surge current capacity.

The CDNBS16-T36C is also an environmental friendly TVS diode due to its energy-efficient design. It utilizes an optimized copper bridge construction to provide improved current handling and higher thermal resistance over other TVS diodes, allowing it to handle higher surge currents and minimizing energy losses.

Conclusion

The CDNBS16-T36C is a TVS diode specifically designed for medium power devices or household electronic circuits. It has an optimized physical profile, which increases its dielectric strength and allows for better cooling. It also provides improved safety protection, due to its integrated internal isolation barrier. The CDNBS16-T36C is energy-efficient and can handle high surge currents with a minimum operating temperature rise, making it an excellent choice for protecting electronic components and devices from voltage spikes.
