Clamping performance and fit
The 1.5KE200CA-T: This bidirectional TVS clamps at 274V max with a 171V reverse standoff voltage and a minimum breakdown of 190V. The 1500W (1.5kW) peak pulse power rating at 10/1000µs waveform means it can absorb a single high-energy surge — a lightning-induced transient on a 120VAC line or a 170V DC bus — without failing short.
Package and environment
The through-hole mounting is straightforward for point-to-point or PCB assembly, but the axial leads demand a hole pattern that matches the body diameter — verify the lead spacing against your board layout before committing to a BOM position.
