The 1.5SMC51AS_R1_00001: This means a 48V nominal rail sees the TVS remain high-impedance under normal operation, then clamp a surge at roughly 70V—well below the typical 80-100V abs-max of downstream switching regulators or DC-DC converters in that rail class.
Surface-mount in DO-214AB, the part suits automated pick-and-place assembly.
Submit an RFQ against your BOM quantity.
This means the TVS can dissipate a 1.5 kW surge lasting one millisecond without damage—sufficient for protecting a 48V DC bus against transients from inductive loads or coupled lightning surges.
