1500W bidirectional Zener TVS — obsolete, last-time-buy sourcing
The 1.5KE110CA-T: It clamps at 152V maximum and has a reverse standoff voltage of 94V, making it suitable for protecting 94V DC rails from transient overvoltage events. This part is officially obsolete per the manufacturer's lifecycle status.
Clamp voltage and breakdown window
The breakdown voltage range starts at 105V minimum, with the clamping ceiling at 152V at the rated 9.9A peak pulse current. The 94V standoff means the device remains non-conducting under normal 94V DC bus conditions, only clamping when the transient exceeds the breakdown threshold. The DO-201AA axial package (also known as DO-27) is through-hole mounted, compatible with standard 0.040-inch diameter lead holes on a PCB or terminal strip.
Sourcing an obsolete TVS for sustainment
With the 1.5KE110CA-T marked obsolete by Diodes Incorporated, no official successor order code is listed. The base product number 1.5KE110 covers a family of unidirectional and bidirectional variants at this voltage rating. For new designs, a parametric search on 94V standoff, 1500W peak pulse, and DO-201 package will yield active alternatives from multiple manufacturers.
