What the 1500 W peak pulse rating means for transient protection
The 1.5KE47CA-B: The 64.8 V clamp ceiling keeps the transient below the absolute maximum rating of downstream 60 V-rated semiconductors.
Bidirectional channel and through-hole package
A single bidirectional channel means the device protects both polarities in one package — useful for AC signal lines or bipolar DC rails where the transient can swing either direction. No need for two back-to-back unidirectional TVS diodes. Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE47CA-B mounts into boards that prefer hand-solder or wave-solder assembly. The DO-201 footprint is common across the 1.5KE series, so PCB layout reuse between voltage variants is straightforward.
Sourcing an obsolete part — what to expect
Available through independent surplus and broker channels. Sourcing is lot-specific — date-code spread, original packaging condition (sealed reel vs bulk bag), and quantity are confirmed at RFQ. No authorized-distributor warranty applies; parts are sourced as-is from factory excess or end-of-life inventory.
