The 1.5SMC47C: It clamps transients at 68.04 V maximum with a 40.2 V reverse standoff, and breaks down at a minimum of 42.35 V.
The DO-214AB footprint and 1500 W rating are common across the 1.5SMC family, so a parametric cross-reference (same package, same standoff voltage range) is feasible but requires verifying the clamping and breakdown thresholds against the original design margin.
DO-214AB (SMC), also referred to as SMCJ in the supplier device package field. It is a surface-mount package with a standard footprint for 1500 W TVS diodes.
