This is the part to reach for when a 12V or 24V automotive bus sees load-dump or inductive kickback spikes that exceed the ECU's input-stage voltage tolerance. ## AEC-Q101 — what the automotive grade buys you AEC-Q101 qualification means this diode passed the Automotive Electronics Council's stress tests for discrete semiconductors: temperature cycling, high-temperature reverse bias, humidity bias, and ESD robustness. The production status is Active per the manufacturer — no end-of-life notice, no last-time-buy window. ## Package and board-fit — DO-214AB (SMC) The DO-214AB (SMC) package is the standard surface-mount footprint for 1500W TVS diodes. For a 1500W pulse, the junction temperature rise is proportional to the pulse duration; the 10/1000µs waveform is the test condition, but real-world transients are often shorter, so the derating curve in the datasheet is the safe guide for repetitive events. Supplied in Tape & Reel packaging, it feeds directly into a pick-and-place line. No MSL floor-life concern for a standard glass-passivated junction — the package is moisture-resistant by construction, not by a moisture-sensitive label.","metaTitle":"1.5SMC47AHR7G TVS Diode, 1500W, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC47AHR7G Zener TVS, 1500W peak pulse, 40.2V standoff, DO-214AB.

It certifies the part has passed temperature cycling, high-temperature reverse bias, humidity, and ESD stress tests per the Automotive Electronics Council standard. This makes it suitable for under-hood and cabin electronics where reliability screening is required."},{"question":"What voltage rail does 1.5SMC47AHR7G protect?","answer":"The reverse standoff voltage is 40.2V, meaning it stays off the circuit below that level. Breakdown starts at 44.7V minimum, and clamping is guaranteed at 64.8V maximum while conducting 24A peak pulse current. This suits 24V automotive systems and 36V nominal industrial buses with headroom for transients."},{"question":"How do I get pricing and availability for 1.5SMC47AHR7G?","answer":"This part is sourced through independent distribution channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC47AHR7G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5SMC47AHR7G when reusing this data.
