The SMC/DO-214AB package is the surface-mount form factor for this power class — the exposed pad on the cathode side must be properly soldered to the PCB pad for thermal relief during clamping events; the 1.5 kW rating assumes adequate heatsinking through the board copper. Power line protection is listed as No, meaning this part is not configured for direct bus-bar or line-to-line protection — it protects a single node from transients on the signal or power rail. Strip packaging indicates tray or loose-reel orientation common for prototyping and small-batch builds — confirm with your CM that the pick-and-place feeder configuration matches the SMC body width before committing to volume assembly.","metaTitle":"Diotec 1.5SMCJ15A TVS Diode, 1500W Peak, 15V","metaDescription":"Diotec 1.5SMCJ15A unidirectional TVS diode, 1500W peak pulse, 15V standoff, 24.4V clamping.
