Parametric fit for the BOM line
The 1.5SMC18AS_R1_00001: The minimum breakdown voltage of 17.1 V sets the threshold where the device starts conducting — anything below that and the TVS stays off, so the protected rail sees no leakage penalty at normal operating voltage. The 59.5 A peak pulse current (Ipp) at the 10/1000 µs test waveform tells you the surge-handling capacity: a 1500 W TVS at this clamp voltage can absorb a single-event surge of that magnitude without exceeding the junction temperature limit of -55°C to 150°C. It is a single-channel unidirectional device with no power-line protection rating — suited for signal or DC rail clamping where the surge polarity is known, not for AC mains or bidirectional applications.
Package and board-level integration
The DO-214AB (SMC) footprint is a common TVS package with a large copper pad on the cathode side for thermal conduction — the board layout should match the recommended land pattern in the Panjit datasheet to keep the thermal impedance low enough for the 1500 W pulse. Supplied in Tape & Reel (TR) and Cut Tape (CT) options, it is compatible with standard pick-and-place assembly and reflow profiles for the SMC body size.
