Its minimum breakdown voltage of 86.7V and maximum clamping at 126V define the protection window for a 78V nominal rail. The 11.4A peak pulse current tells you the surge it can sink before the clamp rises above 126V. Bidirectional construction means it clamps equally on positive and negative transients — useful on AC signal lines or bipolar DC buses where polarity isn't fixed. ## Active production – no LTB scramble needed Microchip lists the SMCJ78CAE3/TR13 as Active. If you already have a layout for a 1.5kW SMCJ TVS, this part drops in without a pad revision. That covers automotive underhood, outdoor telecom cabinets, and industrial enclosures where ambient heat soaks above 85°C. The 1500W rating is derated above 25°C per the standard TVS derating curve — plan for reduced pulse energy at elevated case temperatures.","metaTitle":"SMCJ78CAE3/TR13 TVS Diode – 1500W, 78V Bidirectional","metaDescription":"Microchip Technology SMCJ78CAE3/TR13 Zener TVS: 86.7V min breakdown, 126V clamping, 1500W peak pulse, bidirectional, DO-214AB SMC.

For a bidirectional replacement, any 1.5kW SMCJ TVS with a 78V standoff voltage from Microchip or a second-source supplier (e.g., Littelfuse, Vishay) would be pin-compatible, but confirm the breakdown and clamping voltages match your protection window."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ78CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ78CAE3-TR13 when reusing this data.
