The 1.5KE200CHE3/54: Reverse standoff voltage is 162V typical, with a minimum breakdown of 180V. The part handles 5.2A peak pulse current under the same waveform conditions. The DO-201AA axial-lead package (also known as DO-27) mounts through-hole, making it a straightforward retrofit in existing board layouts.
Sourcing runs through independent distribution channels. Availability is lot-specific; quantities and pricing are confirmed at RFQ time. The axial DO-201AA footprint is common, so a functional replacement from the same 1.5KE family may be possible — confirm the breakdown and standoff voltages against your BOM before substituting.
The through-hole mount is hand-solder or wave-solder compatible; no special moisture sensitivity level applies for this hermetic glass-passivated construction.
