Surface mount mounting with Tape & Reel packaging, compatible with standard pick-and-place and reflow assembly. The bidirectional construction means no polarity marking to worry about — the part clamps equally in both directions, which simplifies PCB layout and reduces orientation errors during placement. ## Rework and handling notes The DO-214AB package reworks cleanly under hot air — the body is large enough to grip with tweezers without slipping, and the solder pads are visible for alignment. No hidden thermal pad underneath, so the part lifts without cooking the board if you preheat the pad area first. Operating temperature range of -55°C to 150°C means the part survives typical reflow profiles without moisture sensitivity issues, though standard MSL handling applies. No power line protection rating — this is a signal-line device, so don't use it on mains or high-energy circuits where the pulse energy exceeds the 1500W rating. The 1.5SMC series is a mature, widely used TVS family, so second-source alternatives exist from other major TVS manufacturers for BOM hedge if needed.","metaTitle":"1.5SMC43CA Littelfuse TVS Diode, 1500W, 36.8V Standoff","metaDescription":"Littelfuse 1.5SMC43CA bidirectional TVS, 1500W peak pulse, 36.8V standoff, DO-214AB.
