The 58 V standoff gives roughly 1.5× headroom above a 24 V nominal rail, which is the typical derating margin applied in industrial 24 V systems to avoid false triggering from supply noise and ringing on switched inductive loads. ## Junction temperature and mounting The junction operating range is -50°C to 150°C, driven by the internal junction temperature rating (TJ). For a TVS protecting a 24 V industrial rail, the steady-state dissipation at standoff is negligible — the junction temperature climbs only during the surge event itself, and the 150°C ceiling gives margin against repetitive transients that don't fully discharge before the next event. Surface-mount DO-214AB fits the standard reflow profile; the SMB/SMC footprint is widely supported across second-source families, so the same footprint accepts alternatives if the Diotec line is unavailable during an allocation period.","metaTitle":"1.5SMCJ58C TVS Diode, 58V Standoff, 1.5kW Peak","metaDescription":"Diotec 1.5SMCJ58C unidirectional TVS diode, 58V standoff, 1.5kW peak pulse, DO-214AB SMC package, -50°C to 150°C junction.

It clamps transient overvoltage events on a protected rail — when the bus voltage exceeds the 64.4 V minimum breakdown, the diode clamps the spike to 103 V maximum, limiting what reaches downstream circuitry. Typical use is on 24 V industrial control rails, sensor buses, and power supply inputs where inductive load switching produces transients above the rail rating."},{"question":"Is there a pin-compatible alternative to the 1.5SMCJ58C in this family?","answer":"The DO-214AB (SMC) package is the industry-standard footprint for 1.5 kW unidirectional TVS diodes — multiple manufacturers offer pin-compatible parts in the same outline and pad layout. Confirm the standoff, breakdown, and clamping ratings match before substituting, since the Diotec breakdown minimum of 64.4 V and clamping ceiling of 103 V are specific to the 58 V standoff rating of this part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ58C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ58C when reusing this data.
