Breakdown begins at 56.7 V minimum, which means the clamping window opens above that threshold and the TVS conducts to ground, clamping the overvoltage before the protected node exceeds its rating. At the peak pulse event, the clamping voltage ceiling is 91.1 V maximum — this is the voltage the downstream circuit actually sees at 16.5 A peak pulse current. For a 51 V rail, the clamping ratio is roughly 1.79×, which is the normal range for a unidirectional Zener TVS in this class. The DO-214AB (SMC) package is the standard surface-mount package for 1500 W bidirectional and unidirectional TVS diodes — the foot pattern matches every major brand's SMC offering, so a second-source search at RFQ is straightforward.
