TVS (transient voltage suppression) diodes are designed with various technologies to protect sensitive electronics from overvoltage transients, such as those caused by lightning, heavy industrial machinery, power surges, static discharge, etc. A particularly popular solution is the ADG467BRS-REEL, a mixed technology TVS diode that combines both Zener and avalanche technologies to offer superior transient protection.

The ADG467BRS-REEL is a transient voltage suppressor diode with bidirectional operation. It can withstand up to 65v of ESD (electrostatic discharge) without damage and is reverse-biased to resist voltage transients up to 17.5v. The device can withstand a high peak current of up to 500A in a unidirectional mode, which makes it suitable for use in applications that require protection from lightning-induced surge events.

The diode\'s Zener mode offers a high breakdown voltage of 17.5V with a low clamping ratio of 1.4 to 1. The reverse-biased avalanche effect provides voltage and current spacing to protect against double breakdown events, further alleviating the failure risk of the device when faced with high energy transients. When combined, these two mechanisms provide an effective method of transient voltage protection for sensitive components.

The ADG467BRS-REEL is ideal for use in automotive, industrial, and consumer applications that require protection from high voltage transient events. Its wide operating temperature range of -55℃ to +150℃ makes it a great choice for extreme weather conditions, and it is also RoHS compliant which makes it suitable for sensitive applications. Additionally, the device is rated to operate up to a frequency of 10GHz, making it a suitable choice for high frequency electrical and electronic applications.

The working principle of the ADG467BRS-REEL is characterized by the reverse-biased avalanche effect, which causes the diode to clamp the voltage across it when the peak current reaches a certain threshold. This prevents the voltage from exceeding a predetermined level and in turn, protects the connected components from damage due to high energy transients. The Zener mode, on the other hand, provides protection from low energy transients while keeping the device\'s voltage across the breakdown voltage level of 17.5v, ensuring that the diode is never subjected to a major breakdown. Both of these components work together to provide superior protection from voltage transients.

In conclusion, the ADG467BRS-REEL is a highly effective TVS diode that offers superior protection from transients. Its combination of Zener and avalanche technologies ensure maximum protection from various types of transients, while its wide operating temperature range and RoHS compliance make it suitable for a variety of applications. Furthermore, the device can be used in high frequency applications up to 10GHz, making it a great choice for a wide variety of needs.
