The SMCJ54CA with SMC TVS ROHS, manufactured by TWGMC, is an unidirectional, surface mount transient voltage suppressor (TVS) device. It is designed to provide protection against voltage transients caused by dampened static discharges, surge, and induction. This device is designed to hold off up to 6000W peak and 200W steady-state power while operating in a range from 6.0V to 170V. The device is constructed using Thermally Enhanced Low Capacitance (TELEC) diode, which is designed to have low capacitive loading and ideal for multimedia and signal line protection. It is also RoHS compliant, lead-free, and halogen-free.
