The 1.5KE15A B0G: The 12.8 V reverse standoff voltage means it stays transparent on a 12 V nominal rail — no leakage or conduction during normal operation — and only starts conducting when the line exceeds the 14.3 V minimum breakdown threshold.
Supplied in bulk packaging — no tape-and-reel, so it is a hand-insert or wave-solder part for prototype runs and low-volume production.
