The clamping voltage is held to 22V at the peak pulse current of 68.2A, giving a 10V headroom above the standoff — a reasonable margin for most 12V logic and power supplies. ## Temperature Grade and Mounting for Harsh Environments ## Active Lifecycle and Sourcing Position","metaTitle":"SMCJ12E3/TR13 TVS Diode – 12V Standoff, 1500W, DO-214AB","metaDescription":"Microchip Technology SMCJ12E3/TR13 Zener TVS diode, 12V reverse standoff, 22V clamping, 1500W peak pulse, DO-214AB SMC package.

The SMCJ12E3/TR13 has a minimum breakdown of 13.3V and clamping at 22V; the SMCJ12A may differ slightly. Both share the DO-214AB footprint, so a board-level swap is possible if the electrical specs align with your protection threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ12E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ12E3-TR13 when reusing this data.
