Obsolete – plan your BOM move
That means onsemi has stopped production and will not accept new orders. Any stock you find is the last of the pipeline — no further manufacturing runs. The field shows 'current', which reflects a legacy catalog listing. The authoritative status from the manufacturer is Obsolete. For a production BOM, this part is a single-source risk that needs a qualified replacement or a last-time buy.
What this TVS does in your circuit
The 1.5KE36AC is a 1500 W peak pulse power TVS diode in the 1.5KE series, designed to clamp voltage transients on power rails, signal lines, or DC buses. The '36' in the order code indicates the reverse standoff voltage — 30.8 V typical — and the 'A' suffix means it is a unidirectional device with a 5 % tolerance on breakdown voltage.
Sourcing an Obsolete part – what to expect
Because the 1.5KE36AC is Obsolete, distributors and brokers may still hold remnant stock, but quantities are finite and declining. We can source and quote this order code against your BOM quantity — confirm availability and current pricing at quote time. For volume or long-term production, a pin-compatible TVS from the same 1.5KE family (e.g., 1.5KE36A, 1.5KE36CA) is the natural first check, though the exact suffix matters for polarity and tolerance.
