1500W pulse — what the clamping voltage means for your rail
The 1.5KE68CA-B: The 58.1V reverse standoff voltage means the protected DC rail should stay below that level during normal operation; the device remains transparent until a transient pushes the line past the 64.6V minimum breakdown threshold.
DO-201 axial — board-level fit and thermal environment
Housed in the DO-201AA (also known as DO-27) axial-lead through-hole package, the 1.5KE68CA-B mounts into a standard 0.040-inch diameter hole pattern.
Single bidirectional channel — symmetrical protection without polarity worry
A single bidirectional channel means the same device clamps positive and negative transients symmetrically — no need to orient the part on the board or worry about reverse-voltage connection. This simplifies pick-and-place verification for through-hole assembly and reduces BOM line count compared to using two unidirectional TVS diodes back-to-back.
