The part is obsolete, so procurement runs through independent surplus channels — availability and pricing are confirmed at the time of an RFQ. No pin-compatible successor is listed on the record. ## What the ratings mean for the BOM The 73.8 V minimum breakdown is where clamping starts; the 118 V maximum clamp at 12.7 A is the voltage the downstream circuitry sees during the pulse. The 1500 W peak pulse power is the rating into an 8/20 µs or 10/1000 µs waveform at 25 °C — derate for ambient above that. The single bidirectional channel means the part clamps both polarities equally — useful on AC signal lines or DC rails where reverse-voltage events are possible. ## Package and board integration The DO-201AA (DO-27) axial package is a through-hole form factor with a 0.052-inch diameter lead. The leads are tin-plated copper; the body is epoxy-molded. Solder into a 0.040-inch plated through-hole on a standard FR-4 board — the lead bend radius should be at least twice the lead diameter to avoid cracking the glass passivation at the body exit. The Tape & Box (TB) packaging ships the parts in a box with the leads oriented in one direction, suitable for hand-insertion or selective-wave soldering. The 1.5KE series shares the same footprint as other DO-201AA TVS diodes from Vishay and competitors — the pad layout is standard.","metaTitle":"Vishay 1.5KE82C-E3/73 TransZorb TVS, 1500W, 118V Clamp","metaDescription":"Vishay 1.5KE82C-E3/73 1500W bidirectional TVS diode, 73.8V breakdown, 118V clamp, DO-201AA axial.

The 1.5KE series from Vishay is broad — a parametric search for DO-201AA, 1500 W, bidirectional, 66.4 V standoff yields electrically similar parts, but the exact order code is not cross-referenced to a specific replacement.
