17.1 V rail protection, 27.7 V clamp ceiling
The 1.5KE20A A0G: Its 27.7 V maximum clamping voltage at 56 A peak pulse current (10/1000 µs waveform) means a downstream device rated for 30 V sees a safe voltage during a surge event.
DO-201 axial — board-level fit
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE20A A0G mounts through-hole on a PCB or terminal block. The DO-201 footprint is a standard across the 1.5KE series, so the same board layout accepts the full voltage range without a pad change.
Active lifecycle, no EOL watch
The part ships in Tape & Box (TB) packaging, suitable for hand-insertion or selective soldering lines. No reel or carrier-tape compatibility issues with standard through-hole feeders.
