The through-hole DO-201AA / DO-27 axial package (1.5KE footprint) is a legacy form factor still widely used in high-reliability and retrofit designs where the board already has the hole pattern. ## Last Buy — sourcing for the BOM line Vishay has placed the 1.5KE36CA-/51 in Last Buy status. This means the manufacturer is no longer accepting volume orders for ongoing production; the remaining stock in the distribution channel is the final inventory. If a replacement is needed for a new design, a parametric search for a bidirectional TVS with a 30.8 V standoff, 1500 W peak pulse, and DO-201 package will yield candidates from the same TransZorb family or competing lines. The existing board layout and hole pattern are the binding constraints.","metaTitle":"1.5KE36CA-E3/51 Vishay TVS, 1500W, 30.8V Standoff","metaDescription":"Vishay 1.5KE36CA-E3/51 TransZorb TVS diode, 1500W peak pulse, 30.8V standoff, bidirectional.
