The 18 V reverse standoff voltage sets the working rail it protects — a 12 V or 15 V supply bus, for instance — while the 20 V minimum breakdown and 39.3 V maximum clamping define the transient window. ## Package and temperature — surface-mount, wide junction range","metaTitle":"STMicroelectronics SMCJ18CA-TR TVS Diode","metaDescription":"STMicroelectronics SMCJ18CA-TR bidirectional TVS diode, 1500W peak pulse power, 18V standoff, DO-214AB (SMC).

Both share the same 18 V standoff, 1500 W rating, and DO-214AB package — the choice depends on whether the protected line requires clamping in both polarities (bidirectional) or only one (unidirectional)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SMCJ18CA-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SMCJ18CA-TR when reusing this data.
