The 1.5KE package code is the same for the entire series; the axial leads fit standard 0.100-inch pitch holes. ## Last Buy — sourcing reality for the BOM line Vishay has marked the 1.5KE200CA-/51 as Last Buy. This means the manufacturer is no longer accepting new orders beyond a defined window; remaining stock is finite and moving through independent distribution. For a production line that depends on this specific TVS, the procurement decision is time-sensitive.","metaTitle":"1.5KE200CA-E3/51 Vishay TVS, 1500W Bidirectional, DO-201AA","metaDescription":"Vishay 1.5KE200CA-E3/51 bidirectional TVS, 1500W peak pulse, 171V standoff, 274V clamp.
