Protection window for an 11.1V rail
The 1.5KE13AT/R: Its 11.1V reverse standoff voltage means it stays transparent on a nominal 11V or 12V DC bus, only clamping when the line exceeds the 12.4V minimum breakdown threshold. The maximum clamping voltage is 18.2V at the rated 82A peak pulse current — this is the voltage the protected circuit must survive during a surge event.
Surge current and junction temperature margin
At 82A peak pulse current, the device shunts the surge to ground while holding the clamp at 18.2V max. The single unidirectional channel means this part clamps only one polarity; reverse-bias protection requires a second device or a bidirectional variant.
Through-hole DO-201 footprint and sourcing posture
Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE13AT/R mounts through-hole — a standard footprint shared across the 1.5KE family. The Tape & Reel packaging suits automated insertion for volume builds. It is quoted to order against BOM quantities through independent distribution, with availability confirmed at RFQ time.
