Junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal environments where the ambient can exceed 125°C. Single bidirectional channel in a DO-201AA (DO-27) axial-lead through-hole package — the body handles the 1500 W pulse without external heatsinking for single-event surges.","metaTitle":"1.5KE220CAHE3/51 Vishay TVS, 1500W, 185V, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE220CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 185V standoff, AEC-Q101.
