Its 8.5V reverse standoff voltage lets it sit on 8.5V nominal power rails without conducting, while the 13.6V clamping ceiling limits the voltage the downstream circuitry sees during a surge. ## Surge Current and Clamp Margin At the 10/1000µs pulse, the device handles 110.3A peak pulse current before the clamp rises to 13.6V. The 8.89V minimum breakdown voltage gives a guard band above the 8.5V standoff — the TVS stays off during normal operation but triggers before the rail exceeds the downstream IC's absolute maximum. For a 12V rail, this part is too low; for 5V or 8.5V rails, the margin is tight enough to protect sensitive logic without nuisance triggering. ## Active Production, Sourced per RFQ Microchip lists the SMCJ8.5CAE3/TR13 as Active. ## DO-214AB Footprint and Reflow The DO-214AB (SMC) package is a standard JEDEC outline with a 0.208-inch body width and gull-wing leads. The cathode band identifies the polarity for unidirectional variants; this bidirectional part has no polarity marking requirement. The solder pad footprint matches the SMCJ series land pattern — no board respin needed if you already use the SMCJ family. Reflow per the solder profile in the datasheet; the package is compatible with lead-free solder processes.","metaTitle":"SMCJ8.5CAE3/TR13 – Microchip Zener TVS, 1500W, 8.5V Standoff","metaDescription":"Active-production Zener TVS diode from Microchip Technology. 1500W peak pulse power, 8.5V reverse standoff, 13.6V clamping.

Both share the same 8.5V standoff and 1500W rating. The bidirectional variant clamps equally on positive and negative surges, which is useful for AC-coupled lines or bipolar supplies where the unidirectional part would need an external diode bridge."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ8.5CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ8.5CAE3-TR13 when reusing this data.
