The DO-214AB (SMC) package is a standard surface-mount footprint with a large copper pad for heat sinking. Hand-solderable with a hot-air station or reflow oven — the package body is big enough to work with tweezers and a fine tip. No power line protection means it is designed for signal and low-impedance power rails, not AC mains.","metaTitle":"1.5SMC18CAHM3/I TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC18CAHM3/I bidirectional TVS diode, 1500W peak pulse, AEC-Q101 qualified, 15.3V standoff, DO-214AB.
