Product details

Obsolete — sourcing the 1.5KE100ARL4 for sustainment

The 1.5KE100ARL4 is marked Obsolete by onsemi. For sustainment of existing designs, procurement should evaluate remaining distributor inventory or a form-fit-function replacement.

1500W Zener TVS — protection window and package

The reverse standoff voltage is 85.5V, with a minimum breakdown of 95V and a maximum clamping voltage of 137V at the peak pulse current of 11A. The DO-201AD axial package is through-hole mounted and suits general-purpose transient suppression across industrial and telecom power rails.

The through-hole axial package is straightforward to hand-solder or wave-solder; no MSL concerns apply.
