For a BOM entering IATF 16949 or AS9100-controlled builds, an AEC-Q101 part removes the qualification-loop variable that a commercial-grade TVS would require additional screening to satisfy. The Automotive classification in the series name and the wide junction temperature range are the design-anchor signals a systems architect uses to confirm the part clears the temperature gate for under-hood deployments without derating to the point of losing the protection function. There is no official second-source order code cross-referenced in the ledger for this specific polarity and clamping voltage — the base product number 1.5SMC6.8 covers the family, but the HE3 suffix carries specific lot-traceability and automotive test-coupon requirements that may not be mirrored by a generic SMC-body alternative. Confirm the suffix-level part if dual-sourcing for safety-critical automotive designs. ## SMC package — board integration reality The DO-214AB (SMCJ) package is the standard SMC outline — it mounts in the same footprint as the SMA and SMB families but the SMC has a higher peak pulse rating than SMA and a lower capacitance than SMB in this voltage class, making it the preferred balance for CAN/LIN and 5 V power rail protection where the capacitance loading on the line must stay below the bus-spec limit. Solder joint integrity on the large cathodic tab is the primary failure mode in vibration-heavy deployments — the thermal cycling difference between the copper tab and the board laminate drives the fatigue. A board-level temperature cycle test per JEDEC JESD22-A104 Condition G or H is the standard qualification screen; for production boards using lead-free solder, the DPAK-class tab size means the reflow profile must allow time for the full solder wetting front under the tab, not just the peripheral lands. ## Sourcing posture and lifecycle No official second-source or pin-compatible alternative is cross-referenced by Vishay for the HE3 suffix at this clamping voltage — any alternate must clear AEC-Q101 lot screening independently before entering a safety-critical automotive BOM. The T&R packaging is standard reel tape-and-reel for high-volume SMT assembly; confirm the reel size and peeling force with your assembly house if changing from a cut-tape source.","metaTitle":"Vishay 1.5SMC6.8AHE3/9AT TVS Diode, 1500W Peak","metaDescription":"Vishay 1.5SMC6.8AHE3/9AT unidirectional TVS diode, AEC-Q101, 1500W peak pulse, 5.8V standoff, 10.5V clamping, DO-214AB SMC.
