The protection window is defined by three voltages: reverse standoff at 11.1V (the rail voltage the diode does not conduct at), breakdown minimum at 12.4V (where clamping starts), and maximum clamp at 18.2V at peak pulse current. A 12V nominal rail that sees transients up to 18V will be held below the downstream component's abs-max rating — the 18.2V clamp is the ceiling the load sees during the event. Vishay has placed the 1.5KE13A-/51 into Last Buy status — the manufacturer is no longer accepting new orders beyond a final purchase window. This is not an obsolete part that vanished overnight, but the clock is running: once the LTB window closes, the only source will be surplus and independent distribution inventory. For a BOM that uses this exact order code, the procurement decision is whether to buy the lifetime quantity now or plan a cross-reference to a still-active TVS with the same 11.1V standoff and 1500W rating in an axial DO-201 package. ## Through-hole axial package and board integration The DO-201AA / DO-27 axial package is a through-hole leaded form factor — the body sits above the board, and the leads are bent and soldered into plated through-holes. This is a legacy footprint common in power supplies, industrial controls, and automotive modules where the TVS is hand-inserted or wave-soldered. The 1.5KE package suffix means the device marking matches the 1.5KE series standard.","metaTitle":"1.5KE13A-E3/51 Vishay TVS, 1500W, 11.1V Standoff","metaDescription":"Vishay 1.5KE13A-E3/51 TransZorb TVS, 1500W peak pulse, 11.1V standoff, 18.2V clamp.
