Temperature range and package durability
The 1.5KE110CA R0G: The DO-201AA (DO-27) axial-lead through-hole package provides a robust mechanical connection and good heat sinking through the leads — the large junction area needed for 1500 W peak pulse dissipates heat effectively into the PCB copper or wiring. Through-hole mounting simplifies manual assembly and rework, and the axial leads allow the diode to be inserted into a board or wired point-to-point in a panel. No power line protection is claimed — this is a signal- or low-power-rail TVS, not a mains surge suppressor.
Sourcing and lifecycle posture
The Tape & Reel packaging (R0G suffix) indicates it ships on a reel suitable for automated pick-and-place, though the through-hole body typically requires hand or wave soldering.
