SMC package and surface-mount profile
The 1.5SMCJ150CA_R1_00001: The SMC (DO-214AB) package is a standard reflow-solderable body for TVS diodes on industrial power supplies and protection boards — the cathode bar is clearly marked with a stripe for orientation, which matters on a bidirectional part because the orientation stripe still identifies the cathode band; for a bidirectional TVS the stripe marks the reference cathode regardless of surge direction. Tape-and-reel packaging is the standard reel format for SMT assembly lines; cut tape is also listed for prototype quantities.
