Product details

Obsolete — sourced through independent channels

Littelfuse has designated the 1.5KE480-B as Obsolete, meaning the manufacturer no longer produces it.

1500 W transient clamp — 408 V standoff to 690.9 V clamping

The 432 V minimum breakdown voltage defines the threshold where the device starts conducting — between the 408 V working voltage and the clamp ceiling, this window protects downstream silicon from transients on a 400 V DC bus or similar high-voltage rail.

DO-201 axial package — wide temperature range

Through-hole mounting in a DO-201AA / DO-27 axial package (supplier device package DO-201), supplied in bulk.
