For a board that already uses this TransZorb part in production, the Last Buy designation means the BOM line needs a last-time-buy quantity decision now. Sourcing through independent distribution channels is the practical path once Vishay's own inventory clears; we can quote against an RFQ for the remaining available stock. ## Transient protection envelope — 1500 W peak pulse The reverse standoff voltage of 5.8 V means the diode stays transparent below that DC rail — it only conducts when a transient exceeds the threshold, protecting downstream silicon. This is a unidirectional Zener-type TVS (one channel), so it clamps positive transients referenced to ground. ## DO-201AA axial package — board-fit note Through-hole axial package (DO-201AA / DO-27), supplier device package 1.5KE. The leads are tin-plated copper; the body is molded epoxy with a color band indicating the cathode. Board assembly uses standard wave-solder or hand-solder profiles — no special reflow profile needed. The axial lead form factor means the part can be mounted standing upright or laid flat against the board. The 1.5KE series is a common footprint across multiple voltage variants, so a single PCB pad pattern serves the whole family.","metaTitle":"1.5KE6.8A-E3/51 Vishay TransZorb TVS, 1500W, 6.8V","metaDescription":"Vishay 1.5KE6.8A-E3/51 TransZorb Zener TVS diode, 1500W peak pulse, 5.8V standoff, DO-201AA.
