Active production — no last-time-buy pressure
The 1.5KE20AHE3_B/C: For a BOM that already qualifies this part, the supply chain does not need a last-time-buy plan or a substitute qualification cycle.
Automotive-grade TVS with AEC-Q101 traceability
The Automotive grade tag on the spec line confirms the part is intended for vehicle-level transient protection, not just commercial or industrial use.
1500 W peak pulse — what the rating means for the clamp
At the clamping voltage of 27.7 V, the device handles 56 A of peak pulse current before the junction exceeds its thermal limit.
Through-hole axial package for board-level surge protection
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE20AHE3_B/C mounts through-hole — the lead bend and body length are standard for this power class, so the footprint matches existing TVS layouts on telecom and automotive boards.
