The 1.5SMC27A-M3/9AT: The unidirectional configuration (single channel) is intended for DC rail protection where the transient is always above the rail voltage; for AC or bidirectional lines, a bidirectional variant would be needed.
The DO-214AB footprint is shared by many 1500 W TVS diodes from other manufacturers (e.g., Littelfuse, STMicroelectronics), but pin-compatibility depends on the specific electrical ratings — confirm the standoff voltage, breakdown range, and clamping voltage match your design before substituting.
