Clamping starts at 6.45V minimum breakdown and hard-clamps at 10.5V maximum, limiting the transient to a level most downstream ICs survive. Peak pulse current is 143A — the 1500W rating means this part absorbs substantial surge energy in a small axial package. ## Through-hole DO-201 package — board integration The DO-201AA (DO-27) axial leaded package is a through-hole form factor rated for the 1500W pulse. The axial leads carry the surge current into the PCB; the body dissipates heat through the leads and the surrounding air — no heatsink required for transient duty. This is not a power-line protection device — it is intended for DC rail and signal-line transient suppression where the 5.8V standoff fits.","metaTitle":"Vishay 1.5KE6.8A/54 TransZorb TVS, 1500W, 5.8V Standoff","metaDescription":"Vishay 1.5KE6.8A/54 TransZorb Zener TVS diode, 1500W peak pulse, 5.8V reverse standoff, 10.5V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE6.8","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.45V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"143A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5KE6.8A/54's peak pulse power and clamping voltage?","answer":"Reverse standoff is 5.8V, breakdown minimum is 6.45V."},{"question":"What package does the 1.5KE6.8A/54 come in?","answer":"DO-201AA (DO-27) axial leaded, through-hole mounting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE6.8A-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-54 when reusing this data.
