The 1500 W rating means it can handle a 12.7 A, 118 V pulse for 1 ms without failing short. ## Where it fits on the board The junction temperature range spans -55°C to 175°C, covering outdoor telecom cabinets, industrial power supplies, and automotive aftermarket modules that see under-hood heat. Because it is unidirectional (one channel), it protects a single DC rail — positive to ground. Bidirectional clamping requires two parts back-to-back or a different order code. The 66.4 V standoff sits just above a nominal 48 V or 60 V bus, so it holds off the normal operating voltage and only conducts during an overvoltage event. For BOM lines that require this exact number, the available stock sits in independent distribution and surplus channels. Quantities are lot-specific, and traceability to the original Vishay date code is confirmed at quote time. A new-design-in should specify the current-production equivalent from the same TransZorb family.","metaTitle":"Vishay 1.5KE82-E3/73 TransZorb TVS, 1500W, 66.4V Standoff","metaDescription":"Obsolete Vishay 1.5KE82-E3/73 TransZorb TVS diode, 1500W peak pulse, 66.4V standoff, 118V clamp.
