This part is in a Last Buy lifecycle phase — the manufacturer has announced end-of-life, and remaining inventory is being drawn down. ## Parametric Fit for 5.8 V Rail Protection The 10.5 V clamping ceiling keeps downstream silicon within its safe operating area during a surge event. The 143 A peak pulse current rating (10/1000 µs) corresponds to the 1500 W power rating — a direct indicator of the surge it can absorb before the junction exceeds its thermal limit. Packaged in a DO-201AA (DO-27) axial-lead through-hole case, it mounts into a standard 0.100-inch pitch hole pattern. ## Sourcing Reality for a Last-Buy Part Vishay has placed the 1.5KE6.8CA-/51 into Last Buy status. No official successor order code is recorded on this listing. The remaining supply flows through independent distribution and surplus channels — each lot is date-code specific and confirmed at RFQ. For a production BOM, the prudent move is to qualify a pin-compatible alternative from the same TransZorb family (same DO-201AA package, same 1500 W power class) while this order code is still findable. The parametric cross — 5.8 V standoff, 10.5 V clamp — is the anchor for the replacement search.","metaTitle":"Vishay 1.5KE6.8CA-E3/51 TransZorb TVS, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE6.8CA-E3/51 TransZorb TVS diode, 1500W peak pulse, 5.8V standoff, 10.5V clamp, DO-201AA axial.
