Single bidirectional channel means one device clamps both polarities — useful on signal or power lines where the transient can swing either direction, saving board space versus two unidirectional diodes back-to-back. ## Obsolete — sourcing via independent channels Vishay has marked the 1.5KE33CHE3/54 as obsolete. The part is available through independent surplus and broker channels; each lot is traceable and confirmed against the BOM at quote time. For a BOM locked to this Vishay order code, the DO-201AA axial footprint and AEC-Q101 qualification are the fixed parameters. A cross-reference to a current-production equivalent would require a board-level review of the clamping voltage and peak pulse current match.","metaTitle":"1.5KE33CHE3/54 Vishay TVS, 1500W, 26.8V, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE33CHE3/54 TVS diode, 1500W peak pulse, 26.8V standoff, AEC-Q101, DO-201AA.
