Packaged in the compact SMA (DO-214AC) form factor, it offers an excellent balance between high power handling capability and PCB space efficiency, making it ideal for modern compact and high-density electronic designs.\u003c\/p\u003e\n\u003cp data-start=\"609\" data-end=\"1017\"\u003eWith a 43V reverse standoff voltage, the SMA6J43A is well-suited for medium-voltage power rails and signal line protection, ensuring reliable operation under normal conditions while rapidly clamping harmful transient spikes. Its ultra-fast response time enables immediate suppression of voltage surges, effectively protecting critical components such as ICs, microcontrollers, and communication interfaces.\u003c\/p\u003e\n\u003cp data-start=\"1019\" data-end=\"1410\"\u003eThe device supports a peak pulse power dissipation of 400W (10\/1000 µs waveform), providing strong energy absorption capability and excellent surge endurance under repeated transient stress. Compared to lower-voltage TVS diodes, the SMA6J43A offers a higher breakdown threshold, making it more suitable for applications requiring enhanced voltage margin and robust system-level protection.\u003c\/p\u003e\n\u003cp data-start=\"1412\" data-end=\"1666\"\u003eBuilt using advanced silicon avalanche technology, it delivers low leakage current, precise clamping performance, and long-term operational stability. This ensures dependable protection for electronic systems operating in harsh electrical environments.\u003c\/p\u003e\n\u003chr data-start=\"1668\" data-end=\"1671\"\u003e\n\u003ch2 data-section-id=\"14at72t\" data-start=\"1673\" data-end=\"1690\"\u003eKey Features\u003c\/h2\u003e\n\u003cul data-start=\"1691\" data-end=\"2181\"\u003e\n\u003cli data-section-id=\"1pzgug6\" data-start=\"1691\" data-end=\"1750\"\u003e400W peak pulse power dissipation (10\/1000 µs waveform)\u003c\/li\u003e\n\u003cli data-section-id=\"yeox02\" data-start=\"1751\" data-end=\"1813\"\u003e43V reverse standoff voltage for medium-voltage protection\u003c\/li\u003e\n\u003cli data-section-id=\"1nnx0zf\" data-start=\"1814\" data-end=\"1880\"\u003eUltra-fast response time for instant surge and ESD suppression\u003c\/li\u003e\n\u003cli data-section-id=\"yncsbo\" data-start=\"1881\" data-end=\"1939\"\u003eLow leakage current for efficient and stable operation\u003c\/li\u003e\n\u003cli data-section-id=\"9c2p6m\" data-start=\"1940\" data-end=\"1995\"\u003eHigh surge capability for repeated transient events\u003c\/li\u003e\n\u003cli data-section-id=\"1pi4stx\" data-start=\"1996\" data-end=\"2064\"\u003eStrong clamping performance for sensitive electronics protection\u003c\/li\u003e\n\u003cli data-section-id=\"wpyu25\" data-start=\"2065\" data-end=\"2113\"\u003eCompact SMA (DO-214AC) surface-mount package\u003c\/li\u003e\n\u003cli data-section-id=\"1u4p9qs\" data-start=\"2114\" data-end=\"2181\"\u003eSilicon avalanche structure for high reliability and durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"2183\" data-end=\"2186\"\u003e\n\u003ch2 data-section-id=\"ce0tqk\" data-start=\"2188\" data-end=\"2205\"\u003eApplications\u003c\/h2\u003e\n\u003cul data-start=\"2206\" data-end=\"2590\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"16pf5pg\" data-start=\"2206\" data-end=\"2258\"\u003eAutomotive electronic systems and ECU protection\u003c\/li\u003e\n\u003cli data-section-id=\"k7606u\" data-start=\"2259\" data-end=\"2306\"\u003eIndustrial automation and control equipment\u003c\/li\u003e\n\u003cli data-section-id=\"1sr2613\" data-start=\"2307\" data-end=\"2353\"\u003ePower supply line protection (AC\/DC rails)\u003c\/li\u003e\n\u003cli data-section-id=\"16uvalg\" data-start=\"2354\" data-end=\"2409\"\u003eCommunication interfaces (RS-485, RS-232, Ethernet)\u003c\/li\u003e\n\u003cli data-section-id=\"1ornlq\" data-start=\"2410\" data-end=\"2452\"\u003eConsumer electronics and smart devices\u003c\/li\u003e\n\u003cli data-section-id=\"1hq3n0r\" data-start=\"2453\" data-end=\"2495\"\u003eLED lighting drivers and power modules\u003c\/li\u003e\n\u003cli data-section-id=\"1h4qeoq\" data-start=\"2496\" data-end=\"2547\"\u003ePortable electronic and battery-powered systems\u003c\/li\u003e\n\u003cli data-section-id=\"e0ehnl\" data-start=\"2548\" data-end=\"2590\" data-is-last-node=\"\"\u003eI\/O ports and signal line ESD protection\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":43786102538305,"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\/sma6j43a-400w-tvs-diode-sma-do-214ac-43v-transient-voltage-suppression-for-esd-surge-protection-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
