1500 W bidirectional transient suppressor
The 1.5KE130CA: It clamps a transient at 179 V maximum while conducting 8.5 A peak pulse current, protecting downstream silicon from voltage spikes on a 111 V nominal rail.
Voltage ratings and clamping behaviour
The reverse standoff voltage is 111 V typical — this is the DC or peak-AC voltage the TVS blocks without conducting. Breakdown occurs at 124 V minimum, and the clamping voltage at full rated current is 179 V maximum. The gap between standoff and clamp defines the protection margin: a 111 V rail sees the transient clamped to 179 V before the pulse energy is absorbed.
Obsolete — sourcing through independent channels
Littelfuse lists the 1.5KE130CA as obsolete. No official successor order code is recorded. The part is available through independent surplus and broker channels; quantities and pricing are confirmed at RFQ.
DO-201 axial package and board fit
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE130CA mounts with the body spanning the trace gap. No power line protection feature is built in — this is a general-purpose transient suppressor, not a mains-rated device.
