Product details

Key ratings for the protection decision

The 1.5KE150: The 128 V reverse standoff voltage means the line it protects should normally stay below this level; clamping begins at 135.45 V minimum breakdown and holds the transient to 217.35 V maximum at the 7.3 A peak pulse current.

Package and board integration

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE150 mounts into a 0.052-inch diameter hole on the PCB. The DO-201 footprint is standard across the 1.5KE series, so a single board layout serves the full voltage range if the BOM needs to swap protection levels.
