P600 axial package — through-hole fit
The 5KP100A/B: The P600 axial package is the standard through-hole form factor for TVS diodes in this power class — it mounts on a 0.4-inch lead spacing and solders into a PCB hole pattern that has been in broad production for decades, making it a natural fit for legacy equipment repair and new industrial panel builds alike. General purpose is the stated application class — YAGEO does not list AEC-Q qualification on this part, so it is positioned for standard industrial and telecom protection rather than automotive or high-reliability screening programs.
