For existing BOM lines, the only supply channel is independent distribution — surplus or new-old-stock lots, confirmed at RFQ. ## 1500 W pulse clamp — the real-world margin That 1500 W rating is the non-repetitive ceiling — for repetitive surges, derate per the pulse derating curve in the datasheet. The 5.8 V reverse standoff voltage means the diode stays fully non-conductive below that DC rail, so it protects a 5 V supply bus without leakage until the transient exceeds the 6.12 V breakdown threshold. A single bidirectional Zener die handles positive and negative transients symmetrically, eliminating the need for two back-to-back unidirectional diodes. ## Sourcing reality for the BOM line With no official successor from Littelfuse, the 1.5KE6.8C is a one-off order code. The 1.5KE series includes many voltage variants, but a drop-in replacement requires matching the 5.8 V standoff, 6.12 V breakdown, and 1500 W pulse rating.","metaTitle":"Littelfuse 1.5KE6.8C TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE6.8C bidirectional TVS, 1500W peak pulse, 5.8V standoff, 144.8A Ipp. Obsolete — sourced to order against RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","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":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"6.12V","Voltage - Clamping (Max) @ Ipp":"11.03V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"144.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power rating of the 1.5KE6.8C?","answer":"1500 W (1.5 kW) for a 10/1000 µs waveform.
