The clamping voltage peaks at 274V at the rated 5.5A peak pulse current — this is the voltage the protected circuit must survive without damage. The single bidirectional channel replaces two unidirectional devices in series, saving board space and reducing part count on the BOM. ## Active production — no end-of-life concerns For a BOM cost engineer, this removes the single-source risk flag that comes with an NRND or obsolete TVS — the part can be specified without planning a near-term replacement spin. ## DO-214AB footprint and thermal path Housed in the DO-214AB (SMC) package, the 1.5SMC200CA is a surface-mount device with a large copper paddle on the cathode side (for unidirectional variants) that doubles as the primary heat path. For this bidirectional part, both terminals are electrically symmetric, but the package body still conducts pulse energy into the PCB copper pour. The 1500W peak pulse rating assumes the junction starts at 25°C; derate the peak power above that per the datasheet curve.","metaTitle":"Littelfuse 1.5SMC200CA TVS Diode, 1500W, 274V Clamp","metaDescription":"Littelfuse 1.5SMC200CA bidirectional Zener TVS diode, 1500W peak pulse power, 274V clamping, DO-214AB.
