Product details

What the 1.5 kW rating means for your protection budget

The 1.5KE18A-G: At the rated 59.52 A peak pulse current, the clamping voltage stays within the 25.2 V ceiling — the part absorbs the transient without letting the rail exceed that level.

Through-hole DO-201AA (DO-27) axial package with the supplier device package designated DO-201. The axial leads suit point-to-point wiring or through-hole PCB mounting where the lead bend radius is controlled to avoid stress on the glass passivation.
