With a nominal DC spark-over voltage of 120V (tested at 100V\/µs), it delivers fast and reliable triggering, ensuring effective diversion of surge energy away from critical circuit components.\u003c\/p\u003e\n\u003cp data-start=\"515\" data-end=\"975\"\u003eBuilt using advanced ceramic gas discharge technology, the SMD3225-120N offers stable impulse spark-over performance (1kV\/µs), high insulation resistance, and low capacitance at 1 MHz, making it ideal for high-speed communication lines and signal-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 conditions.\u003c\/p\u003e\n\u003cp data-start=\"977\" data-end=\"1406\"\u003eCompared to lower voltage variants, the 120V model provides an improved balance between sensitivity and operating voltage margin, making it suitable for systems requiring moderate voltage tolerance with strong surge protection performance. The SMD3225 package offers enhanced thermal dissipation, robust mechanical strength, and compatibility with automated surface-mount assembly, making it ideal for modern compact PCB designs.\u003c\/p\u003e\n\u003cp data-start=\"1408\" data-end=\"1427\"\u003e\u003cstrong data-start=\"1408\" data-end=\"1425\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1428\" data-end=\"1724\"\u003e\n\u003cli data-section-id=\"1egdkpw\" data-start=\"1428\" data-end=\"1469\"\u003eDC Spark-Over Voltage: 120V @ 100V\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"m23dwh\" data-start=\"1470\" data-end=\"1516\"\u003eStable impulse spark-over voltage @ 1kV\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"19kifff\" data-start=\"1517\" data-end=\"1559\"\u003eHigh surge current capability (8\/20µS)\u003c\/li\u003e\n\u003cli data-section-id=\"i71dbo\" data-start=\"1560\" data-end=\"1608\"\u003eLow capacitance @ 1 MHz for signal integrity\u003c\/li\u003e\n\u003cli data-section-id=\"1d9sj2t\" data-start=\"1609\" data-end=\"1639\"\u003eHigh insulation resistance\u003c\/li\u003e\n\u003cli data-section-id=\"10hmw0c\" data-start=\"1640\" data-end=\"1682\"\u003eLong service life and high reliability\u003c\/li\u003e\n\u003cli data-section-id=\"d6x16k\" data-start=\"1683\" data-end=\"1724\"\u003eCompact SMD3225 surface-mount package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1726\" data-end=\"1745\"\u003e\u003cstrong data-start=\"1726\" data-end=\"1743\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1746\" data-end=\"1959\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"cnyvda\" data-start=\"1746\" data-end=\"1782\"\u003eTelecom and networking equipment\u003c\/li\u003e\n\u003cli data-section-id=\"1um754u\" data-start=\"1783\" data-end=\"1813\"\u003eIndustrial control systems\u003c\/li\u003e\n\u003cli data-section-id=\"1qk23rb\" data-start=\"1814\" data-end=\"1850\"\u003ePower supply protection circuits\u003c\/li\u003e\n\u003cli data-section-id=\"d5x4e3\" data-start=\"1851\" data-end=\"1883\"\u003eSmart meters and IoT devices\u003c\/li\u003e\n\u003cli data-section-id=\"146wsbr\" data-start=\"1884\" data-end=\"1908\"\u003eConsumer electronics\u003c\/li\u003e\n\u003cli data-section-id=\"4rke1o\" data-start=\"1909\" data-end=\"1959\" 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":43759676817473,"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\/smd3225-120n-gas-discharge-tubes-smd3225-package-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
