The bidirectional construction (single device, one channel) handles both positive and negative transients on the same line — useful for AC-coupled signal lines or floating supplies where the polarity of the surge is unknown. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE6.8C-/54 as Obsolete. No official successor order code is recorded in the lifecycle entry. No pin-compatible direct replacement from Vishay is documented; a parametric search for a 1500W bidirectional TVS in the same DO-201AA package with a 5.5V standoff and 10.8V clamp is the practical cross-reference path. ## DO-201AA axial package — board-fit note The DO-201AA (DO-27) axial-lead package is a through-hole form factor common to high-power TVS diodes. The 1.5KE series shares the same body size and lead spacing across the voltage range — the footprint is standard and mates with existing PCB layouts for the 1.5KE family. The Tape & Reel packaging (/54 suffix) indicates 54mm tape width for automated insertion.","metaTitle":"Vishay 1.5KE6.8C-E3/54 TransZorb TVS, 1500W","metaDescription":"Vishay 1.5KE6.8C-E3/54 TransZorb bidirectional TVS diode, 1500W peak pulse power, 6.12V breakdown, 10.8V clamp.
