Using advanced avalanche breakdown technology, this device provides ultra-fast response time and precise clamping performance, ensuring effective suppression of transient overvoltage events and improved system reliability.\u003c\/p\u003e\n\u003cp data-start=\"612\" data-end=\"1034\"\u003eWith a working peak reverse voltage of 40V, the 1.0SMBJ40A is well-suited for low-voltage to mid-voltage applications such as DC power rails, communication interfaces, and embedded electronic systems. Its high peak pulse power dissipation of 1000W (10\/1000µs waveform) delivers significantly stronger surge absorption capability compared to standard 600W TVS diodes, enhancing protection under harsh electrical conditions.\u003c\/p\u003e\n\u003cp data-start=\"1036\" data-end=\"1396\"\u003eThe device features low leakage current, stable clamping characteristics, and excellent thermal performance, ensuring efficient operation and long-term durability. Compared to lower voltage variants, the 40V configuration provides increased voltage headroom, reducing the risk of unintended triggering while maintaining strong transient suppression capability.\u003c\/p\u003e\n\u003cp data-start=\"1398\" data-end=\"1737\"\u003eEncased in a compact SMB (DO-214AA) surface-mount package, the 1.0SMBJ40A supports space-efficient PCB design and easy integration into modern electronic systems. It is widely used in consumer electronics, power supplies, communication equipment, and industrial control systems, delivering dependable protection and consistent performance.\u003c\/p\u003e\n\u003chr data-start=\"1739\" data-end=\"1742\"\u003e\n\u003cp data-start=\"1744\" data-end=\"1763\"\u003e\u003cstrong data-start=\"1744\" data-end=\"1761\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1764\" data-end=\"1998\"\u003e\n\u003cli data-section-id=\"mvfvz4\" data-start=\"1764\" data-end=\"1814\"\u003e1000W peak pulse power dissipation (10\/1000µs)\u003c\/li\u003e\n\u003cli data-section-id=\"g1xkx2\" data-start=\"1815\" data-end=\"1851\"\u003e40V working peak reverse voltage\u003c\/li\u003e\n\u003cli data-section-id=\"1330p1p\" data-start=\"1852\" data-end=\"1880\"\u003eUltra-fast response time\u003c\/li\u003e\n\u003cli data-section-id=\"c7zaf4\" data-start=\"1881\" data-end=\"1925\"\u003eLow leakage current and high reliability\u003c\/li\u003e\n\u003cli data-section-id=\"h7s5lb\" data-start=\"1926\" data-end=\"1959\"\u003eExcellent clamping capability\u003c\/li\u003e\n\u003cli data-section-id=\"wu0wqr\" data-start=\"1960\" data-end=\"1998\"\u003eCompact SMB (DO-214AA) SMD package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"2000\" data-end=\"2003\"\u003e\n\u003cp data-start=\"2005\" data-end=\"2024\"\u003e\u003cstrong data-start=\"2005\" data-end=\"2022\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"2025\" data-end=\"2164\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"c0fnif\" data-start=\"2025\" data-end=\"2052\"\u003ePower supply protection\u003c\/li\u003e\n\u003cli data-section-id=\"16ofvcu\" data-start=\"2053\" data-end=\"2078\"\u003eCommunication systems\u003c\/li\u003e\n\u003cli data-section-id=\"146wsbr\" data-start=\"2079\" data-end=\"2103\"\u003eConsumer electronics\u003c\/li\u003e\n\u003cli data-section-id=\"1um754u\" data-start=\"2104\" data-end=\"2134\"\u003eIndustrial control systems\u003c\/li\u003e\n\u003cli data-section-id=\"xftxov\" data-start=\"2135\" data-end=\"2164\" data-is-last-node=\"\"\u003eEmbedded electronic devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"z-0 flex min-h-[46px] justify-start\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"mt-3 w-full empty:hidden\"\u003e\n\u003cdiv class=\"text-center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"RUILON","offers":[{"title":"Default Title","offer_id":43788616138817,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/4468\/5633\/files\/Diodes_Transistors_Thyristors-31-01-02_84534d99-9295-403f-85b4-06c917fa26da.png?v=1767612156","url":"https:\/\/hext.in\/products\/1-0smbj40a-40v-1000w-tvs-diode-smb-do-214aa-high-power-transient-voltage-suppressor-for-surge-esd-protection-ruilon-1","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
