A board-level functional replacement would require a parametric match on the 1500 W peak pulse, 146 V standoff, and 258 V clamping figures, in the same DO-201AA axial footprint. The through-hole DO-201AA (DO-27) package is a standard axial-lead form factor; the unidirectional single-channel layout simplifies polarity in the circuit — the cathode band marks the protected side. No pin-compatible second source is documented in the available records.","metaTitle":"1.5KE180-E3/54 Vishay TransZorb TVS, 1500W, 258V Clamp","metaDescription":"Vishay 1.5KE180-E3/54 TransZorb TVS diode, 1500W peak pulse, 258V clamping, DO-201AA axial.
