Lifecycle reality for a BOM line
The 1.5KE24AHE3/51 is listed as Obsolete by Vishay. For a BOM that already carries this order code, the procurement path is through independent distribution or surplus channels — not the factory's standard supply line.
Key clamping and breakdown parametrics
Reverse standoff voltage is 20.5 V; breakdown occurs at a minimum of 22.8 V.
Automotive qualification and operating envelope
The junction temperature range spans -55°C to 175°C, covering the full automotive ambient with margin.
Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mount. The 1.5KE package footprint is standard across the series — the same board layout accepts any 1.5KE voltage variant. Bulk packaging; no reel or tape for automated insertion.
