The 1.5SMC33AT3G: No official successor or pin-compatible cross-reference is documented from Littelfuse.
Unidirectional Zener construction (single channel) is typical for DC rail protection where the transient polarity is known — the cathode band on the DO-214AB package must be oriented to the positive rail.
