The 1500 W peak pulse power rating is the defining number for this series — it tells you the diode survives a single 10/1000 µs surge event without degradation at the rated current. ## Junction temperature grade and mounting The supplier device package is SMC; the part mounts surface mount, so reflow profile and MSL sensitivity follow the standard moisture sensitivity level for this form factor.","metaTitle":"Littelfuse 1.5SMC6.8AT3G TVS Diode, 1500W Peak, DO-214AB","metaDescription":"Obsolete Zener TVS in DO-214AB SMC package — 5.8V standoff, 10.5V clamping, 1500W peak pulse.

The series covers a range of standoff and breakdown voltages, all sharing the same footprint and peak pulse rating."},{"question":"What is the difference between standoff, breakdown, and clamping voltage on this part?","answer":"The 5.8 V standoff is the continuous reverse voltage the diode blocks in normal operation. The 6.45 V minimum breakdown is where it begins conducting in the Zener region. The 10.5 V maximum clamping voltage is what appears across the diode terminals when the 143 A peak pulse current is flowing — that is the let-through spike the protected circuit sees during a transient event."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC6.8AT3G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC6.8AT3G when reusing this data.
