MicroelectronicsJIP61089B is a Gas Discharge Tube (GDT) SOP-8 RoHS (Restriction of Hazardous Substances) manufactured by JieJie Microelectronics. This component is used to protect a circuit, system, or device from overcurrents and overvoltage transients. It consists of two electrodes sealed in a glass tube filled with a gas mixture of argon, nitrogen, and hydrogen. When operating voltage is reached, the GDT will operate to shunt the excess energy away, thus providing an overcurrent protection for the system. The JIP61089B has a wide range of cut-off voltage levels, from 5V to 150V, and has a rated surge current of up to 5kA. It is a RoHS compliant product, meaning that it meets the European Union’s environmental standards.
