The 1500W peak pulse power rating (1.5kW) is tested with a 10/1000µs exponential waveform — the standard for industrial surge testing per IEC 61000-4-5. For shorter pulses (8/20µs) the part can handle significantly higher peak current, but the 42A figure at 37.5V clamp is the safe limit for the 10/1000µs condition.","metaTitle":"1.5SMC27A R7G TVS Diode, 1500W, 23.1V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC27A R7G Zener TVS, 1500W peak pulse, 23.1V standoff, 37.5V clamp, DO-214AB.

The 'Zener' type classification reflects the avalanche mechanism, but the part is designed for surge protection, not voltage regulation."},{"question":"What is the closest pin-compatible alternative to 1.5SMC27A R7G?","answer":"Within the same 1.5SMC series, the bidirectional variant 1.5SMC27CA R7G shares the same DO-214AB package, standoff voltage (23.1V), and peak pulse power (1500W), but uses two back-to-back Zener junctions for symmetrical clamping. For unidirectional protection, the 1.5SMC27A is the standard choice; the 'CA' suffix is the bidirectional counterpart."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC27A-R7G","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/1.5SMC27A-R7G when reusing this data.
