Rated for 600W peak pulse power (10/1000µs waveform), it handles surges up to 93A in the 8/20µs shape, which covers most industrial and telecom transient requirements. The 20.5V reverse standoff means it stays off the rail below that DC voltage, drawing negligible leakage. Clamping at 42.8V max keeps downstream silicon safe within a typical 48V bus or 24V automotive transient budget. ## Package and mounting — DO-214AA (SMB) Surface-mount in the DO-214AA (SMB) package. The SMB footprint is a common one — same as many 600W-class TVS diodes — so board layout is straightforward if you are replacing or second-sourcing. Junction temperature range covers -55°C to 150°C, which suits outdoor telecom cabinets, industrial control enclosures, and under-hood automotive modules where the ambient can climb. No power line protection rating here (unidirectional only), but for DC rail clamping the bidirectional part is often preferred because it eliminates orientation concerns during assembly. RoHS compliance is standard for the series; no separate qualification entry is needed for most BOM audits.","metaTitle":"STMicroelectronics SM6T24CA TVS Diode, 600W, Bidirectional","metaDescription":"STMicroelectronics SM6T24CA bidirectional TVS diode, 600W peak pulse power, 20.5V standoff, 42.8V clamping.

It clamps transients of both polarities with a single device, which is useful for AC-coupled signal lines or DC rails where reverse polarity protection is needed."},{"question":"What is the closest pin-compatible alternative to SM6T24CA in this component family?","answer":"Within the SM6T series, the unidirectional variant SM6T24A shares the same DO-214AA package and identical breakdown/clamping voltages, but it protects only one polarity. For a bidirectional replacement, stick with the SM6T24CA or any other 'CA' suffix part in the SM6T family — they are footprint- and rating-compatible across the series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T24CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T24CA when reusing this data.
