Last-buy status — plan your BOM now
The 1.5KE62CA-E3/51: Vishay has flagged the 1.5KE62CA-/51 as Last Buy. That means the manufacturer is winding down production — the window to place final orders is closing. If this part is on your BOM, the smart move is to secure your lifetime buy quantity now, or identify a drop-in replacement before the line goes dark.
What the 1500W rating means on the bench
At that pulse, it clamps at 85 V max while shunting 17.6 A. The 53 V reverse standoff means it sits across a 48 V nominal rail and stays out of the way until a transient pushes past 58.9 V breakdown. It is bidirectional, so polarity does not matter — one part handles positive and negative spikes on the same line.
Through-hole axial — field-swappable
DO-201AA / DO-27 axial package, through-hole mount. That is a soldered-in part, not socketed, but the leads are thick enough to survive a couple of rework cycles if you need to swap it on a bench. No lab-grade hot-air station needed — just a soldering iron and a steady hand. The junction temperature range is -55°C to 175°C, so it lives happily in hot enclosures or outdoor gear.
