Protection window and parametric limits
The 1.5KE68CA/B: The 58.1V reverse standoff means the device does not conduct below that rail voltage, making it suitable for 48V DC bus protection where the nominal rail sits well below the clamping threshold. The 64.6V minimum breakdown guarantees the avalanche trigger point, and the 92V maximum clamping voltage limits the let-through energy to downstream components during a surge event. Rated for 16.5A peak pulse current at the standard 10/1000µs test waveform, this part handles repetitive surge events within its power dissipation envelope. Bidirectional channel means a single device protects against both positive and negative transients, simplifying PCB layout for AC signal lines or bipolar DC rails. No power line protection feature — this is a dedicated transient suppressor, not a crowbar or series protection element.
DO-201 axial through-hole package
No secondary mounting hardware required; the lead spacing matches standard 0.4-inch (10.16 mm) hole patterns common in power supply and surge protection board layouts. The box packaging indicates bulk or tape-and-reel availability depending on the ordering quantity — confirm the packaging option at RFQ for automated assembly compatibility.
Active lifecycle and sourcing posture
This means it remains a valid BOM line for new designs and production runs without immediate substitution risk.
