With a nominal DC spark-over voltage of 300V (tested at 100V\/µs), it ensures fast and accurate triggering, effectively diverting surge energy away from sensitive components and improving overall system reliability.\u003c\/p\u003e\n\u003cp data-start=\"530\" data-end=\"1015\"\u003eBuilt using advanced ceramic gas discharge technology, the SMD3225-300N delivers stable impulse spark-over performance (1kV\/µs), high insulation resistance, and ultra-low capacitance at 1 MHz, making it ideal for high-speed communication lines and signal integrity-sensitive applications. Its strong impulse discharge current capability (8\/20µs waveform) and excellent impulse withstand voltage ensure long service life and consistent protection under repeated surge stress conditions.\u003c\/p\u003e\n\u003cp data-start=\"1017\" data-end=\"1433\"\u003eCompared to lower voltage variants, the 300V model provides a higher operating voltage margin, making it suitable for industrial, telecom, and power systems that require enhanced voltage tolerance and robust surge protection performance. The SMD3225 package offers excellent thermal dissipation, mechanical strength, and supports automated surface-mount assembly, making it ideal for modern high-density PCB designs.\u003c\/p\u003e\n\u003cp data-start=\"1435\" data-end=\"1454\"\u003e\u003cstrong data-start=\"1435\" data-end=\"1452\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1455\" data-end=\"1751\"\u003e\n\u003cli data-section-id=\"3pxp7o\" data-start=\"1455\" data-end=\"1496\"\u003eDC Spark-Over Voltage: 300V @ 100V\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"m23dwh\" data-start=\"1497\" data-end=\"1543\"\u003eStable impulse spark-over voltage @ 1kV\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"19kifff\" data-start=\"1544\" data-end=\"1586\"\u003eHigh surge current capability (8\/20µS)\u003c\/li\u003e\n\u003cli data-section-id=\"i71dbo\" data-start=\"1587\" data-end=\"1635\"\u003eLow capacitance @ 1 MHz for signal integrity\u003c\/li\u003e\n\u003cli data-section-id=\"1d9sj2t\" data-start=\"1636\" data-end=\"1666\"\u003eHigh insulation resistance\u003c\/li\u003e\n\u003cli data-section-id=\"10hmw0c\" data-start=\"1667\" data-end=\"1709\"\u003eLong service life and high reliability\u003c\/li\u003e\n\u003cli data-section-id=\"d6x16k\" data-start=\"1710\" data-end=\"1751\"\u003eCompact SMD3225 surface-mount package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1753\" data-end=\"1772\"\u003e\u003cstrong data-start=\"1753\" data-end=\"1770\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1773\" data-end=\"1990\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1whba5f\" data-start=\"1773\" data-end=\"1814\"\u003eTelecom and networking infrastructure\u003c\/li\u003e\n\u003cli data-section-id=\"1um754u\" data-start=\"1815\" data-end=\"1845\"\u003eIndustrial control systems\u003c\/li\u003e\n\u003cli data-section-id=\"ddxgl7\" data-start=\"1846\" data-end=\"1881\"\u003ePower supply and energy systems\u003c\/li\u003e\n\u003cli data-section-id=\"d5x4e3\" data-start=\"1882\" data-end=\"1914\"\u003eSmart meters and IoT devices\u003c\/li\u003e\n\u003cli data-section-id=\"146wsbr\" data-start=\"1915\" data-end=\"1939\"\u003eConsumer electronics\u003c\/li\u003e\n\u003cli data-section-id=\"4rke1o\" data-start=\"1940\" data-end=\"1990\" data-is-last-node=\"\"\u003eLightning and transient surge protection systems\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\n\u003c\/div\u003e","brand":"RUILON","offers":[{"title":"Default Title","offer_id":43759681830977,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/4468\/5633\/files\/VARISTOR-01.png?v=1756461410","url":"https:\/\/hext.in\/products\/smd3225-300n-gas-discharge-tubes-smd3225-package-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
