Clamping performance and fit
The 1.5KE13CA-T: The 11.1 V reverse standoff means the diode conducts negligible leakage below that rail voltage — suitable for protecting a 12 V nominal supply line where the normal operating voltage stays under 11.1 V.
Obsolete — sourcing through independent channels
Diodes Incorporated has marked the 1.5KE13CA-T as obsolete. No pin-compatible alternative is documented from the original manufacturer, so a BOM revision or board spin may be required if a functional replacement is needed.
Package and board integration
Housed in a DO-201AA / DO-27 axial leaded package (DO-201 supplier device), the through-hole mounting is straightforward for point-to-point wiring or PCB insertion.
