{"product_id":"a42-npn-transistor","title":"A42 NPN Transistor","description":"The A42 is an NPN (negative-positive-negative) transistor, meaning it has a p-doped layer between two n-doped layers. It typically comes in a TO-126 package, which is a popular choice for medium-power transistors. As an NPN transistor, it amplifies current flowing from the collector to the emitter when a small current is applied to the base. It consists of three semiconductor regions: emitter (E), base (B), and collector (C).\n\u003cdiv class=\"product_info\"\u003e\n\u003ch1 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003e Features:\u003c\/span\u003e\u003c\/h1\u003e\n\u003cstrong\u003eLow Noise:\u003c\/strong\u003e A42 transistors are often designed for low-noise operation, making them suitable for applications where signal fidelity is crucial, such as audio amplifiers.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHigh Gain:\u003c\/strong\u003e They offer high current gain (hFE) values, enabling efficient amplification of weak signals in various electronic circuits.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMedium Power:\u003c\/strong\u003e With moderate power handling capabilities, they are used in applications that require amplification without excessive power dissipation.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eReliability:\u003c\/strong\u003e These transistors are known for their reliability and stability under normal operating conditions, contributing to their widespread use in electronic designs.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003e Applications:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cstrong\u003eAudio Amplifiers: \u003c\/strong\u003eA42 transistors are commonly employed in audio amplifiers for amplifying weak audio signals from sources like microphones or musical instruments.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSwitching Circuits:\u003c\/strong\u003e They are used in switching circuits to control higher currents or voltages based on a smaller control signal applied to the base.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eLow Collector-Emitter Saturation Voltage\u003c\/li\u003e\n\u003cli\u003eHigh Breakdown Voltage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eType: NPN\u003c\/li\u003e\n\u003cli\u003ePackage: TO-92\u003c\/li\u003e\n\u003cli\u003eIC= 200mA\u003c\/li\u003e\n\u003cli\u003eVCEO= 305Vdc\u003c\/li\u003e\n\u003cli\u003eVCBO= 310Vdc\u003c\/li\u003e\n\u003cli\u003eVEBO= 5Vdc\u003c\/li\u003e\n\u003cli\u003ePD @ TA = 25°C Derate above 25°C= 625mW\u003c\/li\u003e\n\u003cli\u003ePD @ TC = 25°C Derate above 25°C= 1.5Watts\u003c\/li\u003e\n\u003cli\u003eDC Current Gain hFE @ TA = 25°C = 250\u003c\/li\u003e\n\u003cli\u003eTJ, Tstg= -55-150°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eDocumentation\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/drive.google.com\/file\/d\/1SLzmCyOc0uuefBy5fPIn500jYLTWbSl2\/view?usp=drive_link\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x A42 NPN Transistor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":45783718789372,"sku":"TRANS037","price":5.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/A42NPNTransistor.jpg?v=1715583889","url":"https:\/\/kitsguru.com\/fr\/products\/a42-npn-transistor","provider":"KitsGuru","version":"1.0","type":"link"}
