For a 70V rail this means roughly a 1.7× safety margin, which is tight compared to wider-margin TVS choices — check that the downstream semiconductor abs-max rating survives a 113V clamped event at the source impedance of the line. ## Junction temperature range signals where this part lives A junction derated to 125°C under a worst-case 85°C ambient leaves 25°C of headroom at nominal clamping duty — acceptable for intermittent transients but not for a TVS that clamps continuously. If the protected rail runs near its max most of the time, a higher-standby part with more headroom is worth the cost delta. The DO-214AB (SMCJ) package (/) shares the same footprint as the SMA and SMB families — board layout for a SMCJ lands the same pads as an SMB and uses more copper plane than a SMA for thermal relief on the tab.","metaTitle":"Vishay 1.5SMC82A-E3/57T TVS Diode, 70.1V standoff, DO-214AB","metaDescription":"Vishay 1.5SMC82A-E3/57T unidirectional TVS diode, 1500W peak pulse, 70.1V standoff, 113V clamping, DO-214AB SMCJ package.

A 1.5SMC part at this power level handles larger transient energy than the 500W or 600W SMC-series options, so the step-up in clamping performance and peak current (13.3A) matters when protecting bus nodes with higher source impedance or longer cable runs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC82A-E3-57T","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/1.5SMC82A-E3-57T when reusing this data.
