The 1500 W rating at the 10/1000 µs waveform is the standard TVS power metric — it tells you the device can absorb a defined energy pulse without failing. For shorter transients (like 8/20 µs), the peak power capability is higher; for longer pulses, derate accordingly. ## Automotive-grade transient protection The unidirectional Zener structure (one channel) gives a sharp breakdown at 61.2 V minimum — the device starts conducting and clamping the transient before the voltage rises to the 98 V clamp ceiling. The 55.1 V standoff is the maximum DC voltage the diode blocks without conducting leakage current. ## Obsolete — sourced through independent channels Vishay lists the 1.5KE68HE3/54 as obsolete. No official successor order code is recorded.","metaTitle":"Vishay 1.5KE68HE3/54 TVS Diode, 1500W, 55.1V Standoff","metaDescription":"Obsolete Vishay 1.5KE68HE3/54 Zener TVS diode, 1500W peak pulse, 55.1V reverse standoff, AEC-Q101 qualified.","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":"Automotive, AEC-Q101, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","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":"1.5KE68","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"61.2V","Voltage - Clamping (Max) @ Ipp":"98V","Voltage - Reverse Standoff (Typ)":"55.1V","Current - Peak Pulse (10/1000µs)":"15.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the 1.5KE68HE3/54 or check stock?","answer":"Submit an RFQ for the 1.5KE68HE3/54.
