It clamps a 7.02V reverse standoff rail at 12.1V maximum while handling a 124A peak pulse current (10/1000 µs waveform). The 12.1V clamp sits safely below the 30V abs-max rating typical of 12V automotive ECUs and sensors, giving margin on the protected bus. The 1500W peak pulse power covers load-dump and inductive kickback events common in engine-bay wiring. Housed in a DO-201AA (DO-27) axial leaded package, the part mounts through-hole. The 1.5KE body diameter is standard for this power class — the lead spacing on the PCB layout matches the existing 1.5KE footprint. The tape-and-box (TB) packaging option suits hand-insertion or low-volume auto-insertion lines. Listed as Active by Vishay. The AEC-Q101 qualification means the part is manufactured on an automotive-grade line with full PPAP traceability — suitable for new production builds. The 175°C TJ ceiling gives headroom above the 150°C ambient typical in engine-bay transient events.","metaTitle":"Vishay 1.5KE8.2CAHE3_A/D TVS Diode, 1500W, 12.1V Clamp","metaDescription":"Active Vishay 1.5KE8.2CAHE3_A/D bidirectional TVS, 1500W peak pulse, 7.02V standoff, 12.1V clamp, AEC-Q101.
