The 1.5KE8.2A 12.1V 7.79V 7.02V DO-201 TVS ROHS manufactured by Yageo is a transient voltage suppressor consisting of a pair of back-to-back zener diodes in a DO-201 package. It is designed to protect a circuit from destructive voltage spikes, such as those caused by electrostatic discharge, inductive switching, or static charge. The DO-201 package allows for a lower profile than other packages, making it ideal for compact applications. Additionally, it is RoHS compliant making it suitable for use in products that must comply with RoHS regulations.
