Breakdown voltage min is 12.4 V, so a 12 V rail riding at 12.6 V during a fault will trigger the avalanche before the clamp hits 18.2 V — the margin is tight but within spec for transient suppression, not continuous overvoltage. ## Last-buy lifecycle — sourcing what Vishay no longer builds Vishay has placed the 1.5KE13CA-/51 into Last Buy status — the manufacturer is no longer accepting new orders beyond the final procurement window. For a BOM line that depends on this exact TVS, the remaining supply is what independent distribution holds. ## Through-hole axial package — board-fit and temperature range Housed in the DO-201AA / DO-27 axial leaded package, the 1.5KE13CA-/51 mounts through-hole — the lead bend and spacing match the standard 0.375-inch (9.5 mm) lead form used in point-to-point and PCB layouts for high-surge TVS diodes.","metaTitle":"1.5KE13CA-E3/51 Vishay TransZorb TVS, 1500W, 11.1V","metaDescription":"Vishay 1.5KE13CA-E3/51 bidirectional TVS diode, 1500W peak pulse, 11.1V standoff, DO-201AA.
