The 77.9 V minimum breakdown voltage gives a guard band above the 70.1 V standoff — the diode stays transparent during normal line operation but fires before the rail exceeds the safe operating area of the load. ## DO-201AA axial — board-level transient protection Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE82A-/54 mounts into a standard 0.100-inch pitch hole pattern. The wide temp window means no derating is needed at 85 °C ambient for the full 1500 W rating. ## Active lifecycle — sourced per RFQ The base product number is 1.5KE82; the -/54 suffix denotes the lead-free termination and the tape-and-reel packaging option. No pin-compatible second source is formally cross-referenced, but the TransZorb family covers the same DO-201 footprint across voltage grades.","metaTitle":"Vishay 1.5KE82A-E3/54 Zener TVS Diode, 1500W, 70.1V","metaDescription":"Vishay 1.5KE82A-E3/54 TransZorb TVS diode, 1500W peak pulse, 70.1V reverse standoff, 113V clamping.
