Diodes Incorporated lists the 1.5KE13A-B as obsolete. For existing BOM lines, this part is available through independent surplus and broker channels.
With an 11.1V standoff, this TVS protects 12V nominal rails (including automotive 12V systems) from transients. The 18.2V clamp ensures downstream components see voltage below their absolute maximum ratings during a surge event.
No official pin-compatible successor or cross-reference is listed by Diodes Incorporated for this obsolete part. For a replacement, a functional equivalent with similar standoff and clamping voltages in the same DO-201 package would need to be evaluated against the BOM's surge requirements.
It is rated for 1500W (1.5kW) peak pulse power at the 10/1000µs waveform. The peak pulse current at that waveform is 82A.
Standard Diodes Incorporated documentation for the 1.5KE13 series may apply; confirm at order time.
