1.5 kW peak pulse in a DO-201AA axial package
The 1.5KE100A-E3/73: Reverse standoff voltage is 85.5 V; breakdown occurs at a minimum of 95 V, so a 48 V or 60 V rail riding at nominal sees no leakage until the transient pushes the line above the standoff threshold.
Active production — sourcing posture
Vishay lists this part as Active in the product lifecycle, meaning the die and assembly lines are still running; no last-time-buy window or obsolescence notice is in effect. The DO-201AA (DO-27) axial-lead package is a through-hole form factor that mates with standard 0.040-inch diameter plated-through holes — the lead bend and body length match the common TVS footprint used across the 1.5KE family.
