This part is now listed as obsolete by the manufacturer. For existing designs, sourcing runs through independent distribution channels — availability and pricing are confirmed per RFQ against the BOM line. ## Clamping and breakdown thresholds The 9.1A peak pulse current rating (10/1000µs) defines the surge it can absorb before the clamping voltage exceeds the downstream device's abs-max rating. The DO-201AA axial package (DO-27 footprint) is through-hole mounted — the leaded body dissipates pulse energy into the board copper better than a surface-mount equivalent of the same power class. ## Sourcing an obsolete AEC-Q101 TVS The 1.5KE120CAHE3/51 carries AEC-Q101 qualification — the stress and reliability screening required for automotive-grade discrete semiconductors. The bulk packaging (51 pieces per bag) and axial lead form mean the parts store well in standard ESD bins — no moisture sensitivity level concern, no dry-bake requirement before reflow. Confirm the BOM position count and the mating hole pattern before committing the order.","metaTitle":"Vishay 1.5KE120CAHE3/51 TVS Diode, 1.5kW, 102V Standoff","metaDescription":"Obsolete Vishay 1.5KE120CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 102V standoff, AEC-Q101.
