This means a 48 V or 56 V DC rail sees no conduction below the standoff voltage, then the device starts clamping at breakdown and holds the transient to 92 V — a safe margin for downstream semiconductors rated for 100 V or higher. ## Last-buy status and sourcing posture Vishay lists this part in Last Buy status — the manufacturer is closing out the production run. Available through independent distribution channels against an RFQ; the last-time-buy window is active, so BOM lines using this TVS should be sourced now or a replacement qualified. ## Temperature envelope and board integration Through-hole axial DO-201AA package: the leads are 0.96 mm diameter, designed for wave-solder assembly or hand-solder rework. The bulk packaging means the part is loose in a bag, not taped and reeled — factor this into pick-and-place planning if you need machine-insertable format. ## What the 1.5 kW rating means for the BOM The 1500 W peak pulse power is rated for a 10/1000 µs exponential waveform — a standard lightning-surge test pulse per IEC 61000-4-5. At the 92 V clamp, the peak current is 16.3 A; a shorter 8/20 µs surge (common in ESD testing) would see a higher peak current capability because the pulse energy is lower.","metaTitle":"1.5KE68A-E3/51 Vishay TVS, 1.5kW, 92V Clamp","metaDescription":"Vishay 1.5KE68A-E3/51 TransZorb TVS, 1500W peak pulse, 58.1V standoff, 92V clamp.
