Product details

Obsolete — sourced through independent channels

The 1.5KE250-E3/54: The DO-201AA axial package (also known as DO-27) is a through-hole footprint that survives reflow alongside leaded components.

Clamping voltage and trigger thresholds

The minimum breakdown voltage of 225V ensures the device does not avalanche prematurely on nominal rail transients. The 4.2A peak pulse current (10/1000µs) is the current the device can safely shunt. For a given surge energy, the clamping voltage multiplied by this current gives the peak power — 1500W is the product of these two ratings.
