The 143 A peak pulse current at the 10/1000 µs waveform tells you the diode can sink a substantial surge, but the actual current the line sees depends on the source impedance of the transient. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE6.8A-/54 is a hand-solderable or wave-solderable part. The axial leads require through-hole vias on the PCB — the lead diameter and hole size must match the manufacturer's recommended footprint to avoid stress on the solder joint during thermal cycling. The supplier device package is marked as 1.5KE, consistent with the series. The part is available in Tape & Reel (TR) or Cut Tape (CT) packaging for different assembly volumes.","metaTitle":"Vishay 1.5KE6.8A-E3/54 TransZorb TVS, 1500W, 5.8V Standoff","metaDescription":"Vishay 1.5KE6.8A-E3/54 TransZorb Zener TVS diode, 1500W peak pulse, 5.8V standoff, DO-201AA axial.

This is the maximum DC voltage the TVS diode will not conduct under normal operation — it sits across the protected line without loading it. The breakdown voltage range starts at 6.45 V minimum, so a 5 V rail with 10% tolerance (5.5 V max) stays below the breakdown threshold, keeping the diode off during normal conditions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE6.8A-E3-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE6.8A-E3-54 when reusing this data.
