1500W bidirectional TVS — 185V standoff rail clamp
The 1.5SMC220CA TR13 PBFREE: The single bidirectional channel handles both positive and negative surges on the same line, so a single device protects a signal pair or a DC rail referenced to ground. No power-line protection — this is for signal or low-power bus clamping, not AC mains.
Peak pulse current and thermal range
The 150°C maximum junction temperature gives headroom for high-ambient environments like an outdoor telecom cabinet or an engine-bay ECU, where the TVS shares board space with hot-running components.
DO-214AB SMC — standard reflow footprint
The SMC body handles the 1500W pulse without exceeding the package's thermal limit, and the copper pad area under the cathode tab sets the junction-to-ambient thermal resistance. Supplied on Tape & Reel (13-inch reel) — ready for automated pick-and-place assembly. No special dry-storage requirements beyond the standard MSL level for the package.
