The DO-214AB SMC package reflow-solders to a standard land pattern — no special tooling required. The base product number 1.5SMC62 carries the 62 V nominal working voltage in the series; the CA suffix designates the bidirectional bidirectional polarity. This series is catalogued for general-purpose protection — not a safety-certified or IEC 62368 compliant type, so for equipment requiring a listed surge protective device the system-level cert is the governing document, not this component rating alone.

The 53 V standoff makes it suited for 48 V bus protection; the 1500 W peak pulse handles the surge energy budget for most secondary protection roles without needing a bulkier component."},{"question":"What does bidirectional mean for TVS diode selection?","answer":"Bidirectional (the CA suffix) means the diode clamps both polarities — a unidirectional TVS only handles one polarity and would leave the reverse half-cycle unprotected. For rails that swing relative to ground or drive inductive loads, bidirectional polarity is the correct choice and eliminates the need for back-to-back diode pairs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC62CA-E3-9AT","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/1.5SMC62CA-E3-9AT when reusing this data.
