The reverse standoff voltage is 25.6V, meaning it stays out of the way during normal operation and only conducts when the line exceeds that threshold. That 41.4V ceiling is what the downstream silicon sees — it determines whether the protected IC's abs-max rating is respected. ## Automotive qualification and temperature envelope This part carries AEC-Q101 qualification, the automotive discrete semiconductor stress test covering temperature cycling, high-temperature reverse bias, and ESD robustness. The operating junction temperature range spans -55°C to 175°C, which covers under-hood and engine-bay thermal profiles without derating concerns at the high end. The TransZorb series is a mature, field-proven TVS family. The 1.5KE30AHE3_B/C is a unidirectional device — one channel, cathode band oriented — so the PCB silk-screen must match the polarity of the protected rail. The axial DO-201 package is through-hole, which simplifies hand-assembly and rework compared to surface-mount alternatives. ## Sourcing posture and lifecycle The 1.5KE30AHE3_B/C is listed as Active on the manufacturer's lifecycle record. There is no EOL notice or NRND flag on this order code. Sourced through authorized and independent distribution channels; lot traceability and date-code consistency are confirmed at the time of RFQ. For a procurement buyer vetting gray-market risk: the TransZorb series has a consistent marking scheme and the DO-201 package is not a common counterfeit target compared to smaller SMD packages. The laser etch on the body should match Vishay's standard font and include the full part number and date code — any sanded or re-marked bodies are a red flag.","metaTitle":"1.5KE30AHE3_B/C Vishay TVS, 1.5kW, 41.4V Clamp, DO-201","metaDescription":"Vishay 1.5KE30AHE3_B/C TransZorb TVS, 1500W peak pulse, 25.6V standoff, 41.4V clamp.
