The SMDJ6.0CA is an electronic part manufactured by Yageo that consists of two components: a Transient Voltage Suppressor (TVS) and a Surface Mount Diode (SMC). The TVS is a DO-214AB package, a small, rectanglular package that is commonly used for diode, triac, thyristor, and other components. The SMC is a 6.0 Amp, bi-directional, self-conducting, surface mount diode. It is compliant with RoHS, meaning that it does not contain any hazardous substances such as lead, cadmium, mercury, and other toxic materials.
