No power-line protection feature is built in — this is a standard TVS for signal or DC bus clamping, not for AC mains cross-coupled protection. The Tape & Box packaging (/73 suffix) is a Vishay-specific reel-less format, not a standard tape-and-reel; factor this into pick-and-place handling if feeding from a tube or tray adapter. Availability is confirmed per RFQ; pricing and lead time are quoted against the BOM quantity through independent distribution channels. The base product number 1.5KE27 covers the full family; the -/73 suffix denotes the Vishay Green/ROHS-compliant build and the Tape & Box packaging variant.","metaTitle":"1.5KE27A-E3/73 Vishay TVS, 1.5kW, 37.5V Clamp","metaDescription":"Vishay 1.5KE27A-E3/73 TransZorb TVS diode, 1.5kW peak pulse power, 23.1V standoff, 37.5V clamp.
