5.0SMDJ58A with TVS SMC (DO-214AB) RoHS is a surface mount transient voltage suppressor (TVS) diode created by Yageo that is designed as an overvoltage protection component. It is composed of two ultra-fast single breakdown structures, allowing it to provide protection against overvoltage transients. The SMD version has this component in the form of SMT devices and is marked with an SMDJ code. This specific device has a breakdown voltage of 5 volts and a peak pulse power rating of 1500 watts. It is RoHS compliant, which means that it is free of hazardous substances.
