The unidirectional configuration (one channel) clamps only one polarity — positive transients above breakdown; the reverse direction behaves as a forward-biased diode. For AC-coupled lines where both polarities need protection, two back-to-back parts or a bidirectional variant is required. The 175°C upper limit allows operation in hot environments like an engine bay or a sealed enclosure near a heatsink. ## DO-201AA axial — board-fit and replacement reality The DO-201AA (DO-27) axial-lead package is a through-hole form factor with 0.052-inch diameter leads. It replaces earlier 1N6267A-series TVS footprints directly — the body diameter and lead spacing are industry-standard for 1500 W axial parts. The -/54 suffix indicates Vishay's green/RoHS-compliant plating and tape-and-reel packaging (54 = 13-inch reel, 1500-piece quantity). No lead-free reflow profile is needed — wave solder or hand-solder is standard for axial diodes. ## Sourcing — active part, quoted per BOM quantity For a BOM hedge, parametric equivalents in the 1.5KE series (same package, same 1500 W rating, different standoff voltage) exist but are not pin-compatible substitutes; the standoff voltage must match the rail.","metaTitle":"Vishay 1.5KE200A-E3/54 TVS, 1500W, 171V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE200A-E3/54 TransZorb TVS, 1500W peak pulse, 171V reverse standoff, 274V clamp, DO-201AA axial.
