The bidirectional configuration (single device, two back-to-back Zeners in one die) protects both polarities — no need to orient the part on the board. ## Obsolete — sourced through independent channels Vishay has marked the 1.5KE170C-/54 as obsolete. No pin-compatible direct replacement is documented; a parametric search on 1500 W bidirectional TVS in DO-201AA with a 138 V standoff will yield functional alternatives, but each requires board-level verification of the clamping voltage and package footprint.","metaTitle":"1.5KE170C-E3/54 TVS Diode, 1500W, 244V Clamp, Bidirectional","metaDescription":"Vishay 1.5KE170C-E3/54 TransZorb bidirectional TVS, 1500W peak pulse, 244V clamp, 138V standoff.
