DO-214AB SMC — board-fit and storage
The 1.5SMC27AS_R1_00001: The SMC footprint is larger than the smaller SMA/SMB siblings, which helps spread the transient heat into the PCB copper — the pad area under the cathode tab directly sets the thermal impedance for repetitive pulse events. Standard MSL handling applies; store the reels dry to avoid moisture-related popcorning during reflow. The package is rated for general-purpose applications with no power-line protection feature — it is a straight transient suppressor, not a filtered or coordinated protector.
