Product details

Active production — still a current BOM line

The 1.5KE350A B0G: It remains a valid line-item for new builds and replacement orders.

300V standoff, 482V clamp — the protection envelope

Breakdown occurs at 333V minimum; the clamp voltage peaks at 482V at the 3.2A peak pulse current (10/1000µs waveform).

DO-201 axial — board-fit for leaded layouts

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE350A B0G is a through-hole part intended for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The bulk packaging means it ships loose in tubes or bags — no tape-and-reel, so hand-insertion or tube-fed auto-insertion is the assembly path.

Frequently asked questions
