The 12.8 V reverse standoff voltage means the protected rail sits below the clamping threshold during normal operation, and the 14.3 V minimum breakdown ensures the device triggers before the downstream silicon sees damage. ## Last Buy — sourcing a line that is closing Vishay has flagged this part as Last Buy, meaning the manufacturer is no longer accepting new orders beyond a defined window. For a BOM that already carries this order code, the procurement decision is time-constrained: secure the last-time-buy quantity or plan the replacement now. The through-hole DO-201AA axial package (also listed as DO-27) suits point-to-point wiring or PCB mounting with a simple through-hole footprint — no special pad geometry needed beyond the lead spacing.","metaTitle":"Vishay 1.5KE15CA-E3/51 TVS Diode, 1.5 kW, 12.8 V Standoff","metaDescription":"Vishay 1.5KE15CA-E3/51 TransZorb TVS, 1500W peak pulse, 12.8V standoff, 21.2V clamp, DO-201AA.
