require?\u003c\/strong\u003e\u003cbr\u003eA: The SLP740C is a logic-level or standard gate drive MOSFET. Refer to the datasheet for the specific VGS(th) threshold voltage and recommended gate drive voltage for full enhancement. Typical gate drive is 10–15V for full RDS(on) performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this in a 230VAC mains-connected circuit?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The 400V VDS rating provides adequate margin above the 230VAC mains peak voltage (~325V peak). Always include appropriate snubber circuits and gate drive protection in mains-connected designs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum junction temperature?\u003c\/strong\u003e\u003cbr\u003eA: Refer to the SLP740C datasheet for TJ(max). Most TO-220 power MOSFETs are rated to 150°C junction temperature. Ensure adequate heatsinking to keep TJ well below this limit in continuous operation.\u003c\/p\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e5× SLP740C N-Channel MOSFET TO-220 (400V 10.5A)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":46985499279595,"sku":"\u003cnone\u003e","price":16.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/slp740c-n-channel-mosfet-to220-400v-10-5a.webp?v=1761284124","url":"https:\/\/keszoox.com\/products\/slp740c-n-channel-mosfet-to-220-400v-10-5a-5pcs","provider":"Keszoox","version":"1.0","type":"link"}
