1500 W peak pulse at 92 V clamp — the real protection envelope
The 1.5KE68CA B0G: The 58.1 V reverse standoff voltage means it stays transparent on a 48 V nominal rail — the device only starts conducting when the transient exceeds the 64.6 V minimum breakdown threshold. At the rated 17 A peak pulse current the voltage clamps at 92 V maximum, which is the figure the downstream silicon sees. For a 48 V bus protected by this part, that 92 V clamp gives a 44 V headroom above the rail — enough to keep a downstream 100 V-rated DC-DC converter or 80 V-rated MOSFET in its safe operating area during a surge.
Bidirectional, single-channel, through-hole — fit and function
There is no power-line protection feature; this part is designed for signal and DC rail transient suppression, not mains AC input clamping.
Active production — sourcing posture
Sourced through authorized and independent distribution channels; pricing and lead time are confirmed at the time of the RFQ against the BOM quantity.
