What this 1.5kW Zener TVS covers on the rail
The 1.5KE12A_R2_00001: The 10.2V standoff means it sits across a 12V nominal rail without conducting in normal operation, then clamps transients to 16.7V — enough headroom for most downstream regulators rated to 20V or higher. Packaged in a DO-201AE axial leaded body, it is a through-hole part suited for point-of-use transient suppression on power input stages or DC bus lines where board space is not the constraint.
Obsolete — sourcing through independent channels
For existing BOM lines, this part is available through independent surplus and broker channels.
