What the 1500W rating means for your protection design
The 1.5KE200CAHE3_A/D: That 1500W rating means it can absorb a 5.5A surge current while clamping the transient to 274V maximum — the voltage your downstream circuitry actually sees during the event. The breakdown voltage range starts at 190V minimum, so the device stays off until the transient pushes the line above that threshold.
Automotive-grade reliability and temperature range
This part carries AEC-Q101 qualification, the automotive discrete semiconductor stress test. That means it has passed temperature cycling, high-temperature reverse bias, and ESD robustness screening required for under-hood and chassis-mounted electronics.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE200CAHE3_A/D mounts through-hole. The 1.5KE supplier device package designation is standard across the Vishay TransZorb family.
