The SMCJ210A with 340V 237V 210V SMC(DO-214AB) TVS ROHS is a bidirectional transil diode manufactured by Yageo. It is designed to protect sensitive electronic components, such as ICs, processors, gate arrays and other sensitive devices, from electrical overstressing due to electrostatic discharge (ESD) and voltage transients. This device features a robust and fast response to voltage transients up to 34V, and suppresses standard ESD pulses exceeding 8kV in contact discharge mode. Its low capacitance and low forward voltage make it ideal for high speed data interfaces. The DO-214AB package is compatible with automated assembly processes and is RoHS compliant.
