Unidirectional only, one channel — it clamps positive transients relative to ground and does not reverse-bias protect against negative swings; the reverse-standoff rating of 58.1 V typ sets the continuous working voltage the diode must block in normal operation. ## Clamping architecture and what the ratings mean on the board The breakdown voltage minimum is 64.6 V — above this the TVS avalanche characteristic turns on and shunts the surge current, keeping the clamped node at or below the clamping voltage spec of 92 V max at the 17 A peak pulse rating (10/1000 µs waveform). The 1.5 kW peak pulse rating is a single-event, non-repetitive figure for the 10/1000 µs surge shape; if the board sees repetitive transients (switching, relay kickback) above the rated repetition duty, derate per the power-derating curve or move up to a higher-peak-power series. With a reverse standoff of 58.1 V typ, the diode sits idle on a 48 V nominal rail with margin to spare; the 64.6 V minimum breakdown keeps the rail clean under normal conditions, and the 92 V clamping ceiling protects downstream silicon from transient spikes that would otherwise punch through gate oxides or exceed absolute-maximum ratings. ## Sourcing posture and lifecycle Supplied in Tape & Reel (TR) orientation for automated SMT pick-and-place; the DO-214AB SMC footprint is a widely supported package across the TVS diode market, which simplifies second-source qualification on automotive platforms requiring BOM hedge. No stock-holding claim — a quote clears the channel and lot-traceability requirement before committing.","metaTitle":"1.5SMC68AHM6G TVS Diode, 1.5 kW, 92 V Clamping, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC68AHM6G, unidirectional automotive TVS diode, 58.1 V standoff, 64.6 V min breakdown, 92 V clamping at 17 A peak pulse, AEC-Q101","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC68","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"64.6V","Voltage - Clamping (Max) @ Ipp":"92V","Voltage - Reverse Standoff (Typ)":"58.1V","Current - Peak Pulse (10/1000µs)":"17A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2104","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC68AHM6G/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between a Zener and a TVS diode on this part number?","answer":"The 1.5SMC68AHM6G is listed as a Zener type but configured as a unidirectional TVS (transient voltage suppressor) diode — it uses the Zener avalanche characteristic to clamp voltage transients, not to regulate.
