At 64.6V minimum breakdown it begins conducting, and the 10/1000µs surge test waveform (the standard automotive and telecom surge event) pushes it to a 92V clamping ceiling at 16.3A peak. That 1500W peak pulse rating is the 10/1000µs figure — the same test wave used in ITU-T K.44 surge immunity testing for telecom power and ISO 7637-2 for automotive conducted transients, so the 1.5SMC family slots directly into those qualification test plans. ## AEC-Q101 automotive grade and thermal margin The AEC-Q101 qualification screens this part for the stress sequence used on automotive electronics programs — temperature humidity bias, high-temperature reverse bias, and temperature cycling per AEC-Q101. The junction temperature range is -65 to 150°C — the upper bound matters for under-hood and transmission-control deployments where ambient can approach 125°C and the diode self-heats from clamping events. Confirm the PPAP package and the AEC-Q101 lot traceability requirements with your component engineer before committing to a new automotive program; the H-suffix on the order code designates the automotive grade within the 1.5SMC series. ## SMC (DO-214AB) footprint and assembly The DO-214AB (SMC) package is the medium-crown variant — larger anode and cathode pads than the DO-214AA (SMA) but the same footprint pitch, which means the land pattern and solder-mask-defined pad geometry are identical across those two grades. Supplied on tape-and-reel; the cathode band on the package body marks the unidirectional polarity, and the stripe must orient correctly on the PCB before reflow — there is no polarity reversal tolerance on a unidirectional TVS. Vishay lists this as Active. Confirm lot date code and AEC-Q101 conformance documentation requirements before placing the order, particularly for automotive or telecom infrastructure programs that require PPAP or IEC 62368-1 compliance evidence.","metaTitle":"1.5SMC68AHM3_A/I TVS Diode 1500W 92V Clamping","metaDescription":"Vishay 1.5SMC68AHM3_A/I unidirectional TVS Zener, AEC-Q101, 1500W peak pulse 10/1000µs, 58.1V standoff 92V clamping 16.3A, DO-214AB SMC, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive, Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC68","Operating Temperature":"-65°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)":"16.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3331","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC68AHM3_A%2FI/alternatives.json"},"ai":{"faq":[{"question":"Who supplies the 1.5SMC68AHM3_A/I and how is it quoted for volume orders?","answer":"Confirm the H-suffix automotive grade and the AEC-Q101 conformance documentation requirements with your distributor before committing a volume order."},{"question":"What type and series is the 1.5SMC68AHM3_A/I?","answer":"It is a unidirectional Zener-based TVS (Transient Voltage Suppressor) diode, listed as the Automotive, AEC-Q101 qualified 1.5SMC TransZorb® series from Vishay General Semiconductor — Diodes Division."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC68AHM3_A-I","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/1.5SMC68AHM3_A-I when reusing this data.
