Obsolete — sourcing through independent channels
The 1.5KE150-E3/54: Available through independent surplus and broker channels. Quantities are lot-specific; availability and pricing confirmed at RFQ time. No stock-holding claim — sourced per request against the BOM line.
1500 W peak pulse — 215 V clamp ceiling
Reverse standoff voltage is 121 V typical, meaning the diode draws negligible leakage below this rail voltage. Breakdown occurs at a minimum of 136 V, triggering conduction to clamp the transient. Single unidirectional channel — protects one rail or signal line against positive-going transients. No power line protection (bidirectional) capability; use two devices back-to-back for AC line applications.
DO-201AA axial — through-hole board fit
Housed in the DO-201AA (DO-27) axial leaded package, through-hole mount. The 1.5KE series supplier device package code is 1.5KE. Store the reels dry; the axial leads are tin-plated and solderable per standard wave or hand-solder profiles.
