The 1.5SMC7.5A_R1_00001: Junction temperature runs to 150°C, which gives thermal headroom for short bursts before the clamping characteristic shifts.
The SMC (DO-214AB) package is a standard surface-mount outline — reflow profile follows the lead-free solder window, and the tab solder joint carries the majority of the thermal path to the board. Tape-and-reel and cut-tape options cover both production run and prototype quantities; the part is unidirectional so polarity at assembly matters — the cathode stripe on the body marks the active polarity.
