TVS-Diodes, or Transient Voltage Suppressors, are a power-dissipating electronics component designed to protect sensitive electronic components from excessive voltage. The CD214A-T78CALF is a unidirectional (biased) voltage suppression diode that can effectively protect against overvoltage spikes in a system. It is a cost-effective way to handle overvoltage transients and is commonly used for telecommunications, laptop computing, automotive, and industrial control systems.

The CD214A-T78CALF is made from a specially formulated planar technology that provides excellent performance characteristics for overvoltage protection. The diode has low capacitance, which allows the device to remain in the OFF-state for longer when an overvoltage event occurs. This ensures that the device will not switch to the ON-state until the voltage has dropped back to a safe level, providing an effective protection against overvoltages. The device features a low standoff voltage of 14V, which is suitable for many common applications.

The working principle of the CD214A-T78CALF is based on the two-junction, or Zener, breakdown. When a voltage is applied to the diode, a small amount of current will flow through the diode as the electrons gain enough energy to cross the two junctions. As the voltage increases, the current will increase, until it finally reaches a threshold and the diode will breakdown. At this point, the diode will remain in the ON-state until the voltage drops back to a safe value. This functionality prevents any further damage from overvoltage transients.

The CD214A-T78CALF is designed for a wide range of applications. It can be used for DC and AC line protection, lightning protection, application power supply, overvoltage protection, and inrush current suppression. In addition, it is a good choice for applications with high noise levels, such as automotive and industrial controllers. Its excellent surge capability ensures that even in the most challenging scenarios the device will continue to provide effective protection.

The CD214A-T78CALF is an excellent example of a reliable and cost-effective voltage suppression diode from Longting. Its wide application range and excellent surge capability make it a popular choice for many systems which require dependable overvoltage protection. Additionally, its low capacitance provides a high immunity to noise, making it an ideal choice for applications such as automotive and industrial controllers.
