The single bidirectional channel handles positive and negative transients in one package — useful where the protected line sees symmetrical surges, such as AC-coupled data interfaces or ungrounded DC rails. ## Package and deployment context Housed in a DO-214AB (SMC) surface-mount package, the large tab area conducts heat to the PCB copper pour — keep the pad size per the datasheet recommendation to stay within the 1500 W peak capability at the rated pulse width. Surface-mount assembly — no through-hole lead forming; the part reflows with standard SnPb or SAC solder profiles. Availability and current pricing are verified per inquiry.","metaTitle":"Littelfuse 1.5SMC16C TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5SMC16C Zener TVS, 1500W peak pulse, 13.6V standoff, 23.63V clamp, DO-214AB.
