TVS - Diodes

TVS diode, or transient voltage suppressor, is an essential device used in the protection circuit of electrical and electronic systems. The utility of the TVS is to absorb the voltage spikes generated due to lightning and line transients, and protect the system from being damaged by the over voltage or over current conditions.The BZG04-12TR3 is a unidirectional TVS diode that comes in a SOD-123F package. It is primarily used in the protection of over voltage transients generated due to inductive switching. The device features a low clamping voltage for surge suppression, and is designed to protect electronic components from damage due to surge currents.The BZG04-12TR3 can be used in a variety of application fields, such as automotive systems, consumer electronics, industrial electronics, and power supplies. The device is specifically designed for high speed switching applications, and can be used in a wide range of environments, from -55°C to 125°C.The device features a reverse limiting voltage of 12V, and a very low capacitance for minimal signal distortion. The peak pulse power is 400 W at 8/20μs waveform, and its maximum rated peak pulse current is 2A. The BZG04-12TR3 has reverse leakage current of a maximum 3μA at 12V typ.The working principle of the BZG04-12TR3 is very simple: when an electrical system is subject to a voltage surge, the device responds to it by raising its capacitance. This rapidly reduces the overvoltage above a certain threshold and absorbs the surge, thus keeping the system safe from any damaging levels of electricity. The device achieves this by utilizing the intrinsic property of the junction between two different materials, and the special characteristic of the material that connects them.When the TVS comes into contact with an overvoltage, a large reverse-bias current flows across the junction. This current is called a “clamping current,” and it prevents the voltage from exceeding the device’s clamping voltage. The device also has a recovery time, which is the time it takes for it to return to its normal condition after absorbing the overvoltage. The TVS diode is an incredibly efficient form of protection from overvoltage and overcurrent conditions, making it an invaluable part of many electrical and electronic systems. The BZG04-12TR3 is a particularly effective device, offering enhanced protection in a wide range of applications, and it\'s ability to handle high speeds without signal distortion makes it ideal for high-speed switching applications.
