The 1.5KE62CA_R2_00001: The 53 V reverse standoff means it sits across a 48 V rail without conducting; the 58.9 V minimum breakdown is the point it starts clamping. Bidirectional construction (single device, one junction) protects against both positive and negative transients — useful on AC-coupled signal lines or DC rails where reverse polarity is a risk.
Package and rework reality
DO-201AE axial through-hole package — the leads are thick enough to handle the surge current without fusing, and the body stands up to a hot-air station for removal and replacement. No moisture sensitivity level to track; the -65 to 175 °C operating range means it survives wave solder and reflow without derating.
Obsolete — sourcing path
Marked obsolete by Panjit. The DO-201AE footprint is common across the 1.5KE family, so a parametric match (same standoff, same package) from another brand may fit without a board change.
