Built using advanced avalanche breakdown technology, this device ensures ultra-fast response time and precise clamping performance, delivering reliable overvoltage protection in demanding environments.\u003c\/p\u003e\n\u003cp data-start=\"572\" data-end=\"988\"\u003eWith a working peak reverse voltage of 40V, the SMBJ40A is ideal for higher-voltage applications requiring stable and efficient surge suppression. It offers a high peak pulse power dissipation of 600W (10\/1000µs waveform), enabling it to safely absorb and dissipate transient energy. The diode features low leakage current and optimized clamping characteristics, improving system efficiency and long-term durability.\u003c\/p\u003e\n\u003cp data-start=\"990\" data-end=\"1336\"\u003eCompared to lower voltage TVS diodes, the 40V configuration provides greater voltage headroom, minimizing the risk of false triggering in circuits with voltage fluctuations while maintaining strong protection capability. Encapsulated in a compact SMB (DO-214AA) surface-mount package, it supports space-efficient PCB layouts and easy integration.\u003c\/p\u003e\n\u003cp data-start=\"1338\" data-end=\"1563\"\u003eThe RUILON SMBJ40A is widely used in power supplies, automotive systems, telecom equipment, industrial control units, and consumer electronics, ensuring consistent performance, enhanced reliability, and extended service life.\u003c\/p\u003e\n\u003chr data-start=\"1565\" data-end=\"1568\"\u003e\n\u003cp data-start=\"1570\" data-end=\"1589\"\u003e\u003cstrong data-start=\"1570\" data-end=\"1587\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1590\" data-end=\"1822\"\u003e\n\u003cli data-section-id=\"16qv8fr\" data-start=\"1590\" data-end=\"1639\"\u003e600W peak pulse power dissipation (10\/1000µs)\u003c\/li\u003e\n\u003cli data-section-id=\"g1xkx2\" data-start=\"1640\" data-end=\"1676\"\u003e40V working peak reverse voltage\u003c\/li\u003e\n\u003cli data-section-id=\"1330p1p\" data-start=\"1677\" data-end=\"1705\"\u003eUltra-fast response time\u003c\/li\u003e\n\u003cli data-section-id=\"1ywjjbp\" data-start=\"1706\" data-end=\"1748\"\u003eLow leakage current and high stability\u003c\/li\u003e\n\u003cli data-section-id=\"1fm55tz\" data-start=\"1749\" data-end=\"1783\"\u003eExcellent clamping performance\u003c\/li\u003e\n\u003cli data-section-id=\"wu0wqr\" data-start=\"1784\" data-end=\"1822\"\u003eCompact SMB (DO-214AA) SMD package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1824\" data-end=\"1827\"\u003e\n\u003cp data-start=\"1829\" data-end=\"1848\"\u003e\u003cstrong data-start=\"1829\" data-end=\"1846\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1849\" data-end=\"2001\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"c0fnif\" data-start=\"1849\" data-end=\"1876\"\u003ePower supply protection\u003c\/li\u003e\n\u003cli data-section-id=\"1x8ffoa\" data-start=\"1877\" data-end=\"1903\"\u003eAutomotive electronics\u003c\/li\u003e\n\u003cli data-section-id=\"1f42zxu\" data-start=\"1904\" data-end=\"1938\"\u003eTelecom and networking systems\u003c\/li\u003e\n\u003cli data-section-id=\"1tr9d36\" data-start=\"1939\" data-end=\"1971\"\u003eIndustrial control equipment\u003c\/li\u003e\n\u003cli data-section-id=\"anjcvz\" data-start=\"1972\" data-end=\"2001\" data-is-last-node=\"\"\u003eConsumer 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":43788154372161,"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\/smbj40a-40v-600w-tvs-diode-smb-do-214aa-transient-voltage-suppressor-for-surge-esd-protection-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
