Breakdown occurs at 48.5 V minimum, and the clamping voltage is capped at 70.1 V at the 22 A peak pulse current. ## Sourcing and lifecycle posture The AEC-Q101 qualification and automotive grade confirm it meets the reliability and PPAP requirements for automotive OEMs — a key consideration for BOM lines that must pass customer-specific qualification audits.","metaTitle":"1.5KE51CAHE3_B/C Vishay TVS, Bidirectional, 1500W, DO-201AA","metaDescription":"Vishay 1.5KE51CAHE3_B/C bidirectional TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101 automotive grade.
