That 1500 W figure is the maximum dissipation for a 1 ms pulse — it does not mean the part handles 1500 W continuously. On a 12 V rail, this clamps a transient well below the downstream regulator's abs-max, so the board survives a load-dump event without the regulator letting go. Vishay has flagged this part as Last Buy. That means the manufacturer is winding down production — there is a finite window to place final orders before it goes end-of-life. ## Package and rework reality Through-hole DO-201AA (also DO-27) axial package — two leads, no orientation ambiguity. The body is epoxy-encapsulated with a tin-plated copper lead frame. Rework is straightforward: clip the leads, desolder the stubs, and solder in a fresh part. No hot-air station needed, no pad-lifting risk.","metaTitle":"Vishay 1.5KE7.5A-E3/51 TransZorb TVS, 1500W, 6.4V Standoff","metaDescription":"Vishay 1.5KE7.5A-E3/51 TransZorb Zener TVS diode, 1500W peak pulse, 6.4V standoff, DO-201AA.
