Radio CompanyThe 1.5SMC220A is a transverse voltage surge stopper (TVS) diode manufactured by Leshan Radio Company. It is based on the Super MiniMELF (SMC) package, specifically DO-214AB. This component is RoHS-compliant, meaning it meets certain restrictions on the use and amount of hazardous substances contained within the product. This TVS diode is designed to suppress transverse voltage surges with a maximum peak pulse power dissipation of 220W. It features a low capacitance of 2.8pF, fast response time of 2.5ns, and low leakage current of 400nA. The 1.5SMC220A has a reverse stand-off voltage of 1.5V, a breakdown voltage of 11V, and a clamping voltage of 19V. It is recommended for applications such as USB ports, Ethernet ports, audio lines, and consumer electronics.
