TVS - Diodes

A Transient Voltage Suppression (TVS) diode is an electronic component that is designed to protect other devices from overvoltages and protect circuits from transient voltage spikes. These devices are commonly used in communications, consumer electronics, automotive and industrial applications.

The BZW04-28BHR1G is a bidirectional, high-power TVS diode that provides high levels of voltage and current protection for applications ranging from consumer electronics to automotive and industrial. It offers superior ESD and device protection up to 25kV when used in combination with appropriate other EMC components. The device is suitable for use in high-reliability applications such as automotive and industrial electronics, and is capable of sustaining more than 25,000 ESD strikes.

The BZW04-28BHR1G is a monolithic overvoltage suppressing diode with a rated breakdown voltage of 28V. The device has an ESD rating of 25kV and a response time of 10ns. It is capable of handling pulse current up to 800mA, with a maximum working voltage of 26V and a leakage current of 0.1mA. The diode is designed to provide an exceptional level of protection against electrical transients, surges, and ESD.

The working principle of the BZW04-28BHR1G is relatively simple. The diode is a bidirectional device that is designed to conduct only during an overvoltage or ESD event. When the voltage exceeds the breakdown threshold of the diode, it triggers a protective action by quickly conducting the energy away from the device being protected. This helps to prevent device damage caused by transients or surges. The diode draws a very small amount of current while in its normal "off" state, so it does not interfere with normal operation.

The BZW04-28BHR1G is typically used to protect electronic equipment and modules from overvoltage and ESD events. It is a reliable and cost-effective solution for applications such as automotive, consumer, and industrial electronics. The diode is also used to provide ESD protection in a variety of applications, including digital and analog circuits, personal electronics, and RF circuits.

The BZW04-28BHR1G is a robust and reliable device that is designed to provide a high level of protection from both overvoltages and ESD events. It has a wide operating temperature range and can handle up to 800mA of pulse current. The device is a cost-effective solution for a wide range of applications, from consumer electronics to industrial and automotive applications.
