The BC547 transistors have such a wide range in current gain that BC337 transistors can replace them and some circuits will work well and others won't, the same as if BC547 transistors were used. First of all, need to understand the application for Power MOSFET. BC546, BC547, BC548, BC549 and BC550 are NPN types, while BC556, BC557, BC558, BC559 and BC560 are PNP types and form complementary pairs with the NPN type. The difference between these two are These transistors are the direct modern equivalent replacements to the earlier BC107, BC108, and BC109.

As early as 1979, Ferranti Semiconductors were manufacturing the ZTX107, ZTX108, and ZTX109 transistors which were a direct equivalent replacement for the Philips BC series. Components101 is a resource dedicated for electronics design engineers, covering product news, analysis and articles on latest electronics components. BC546, BC547, BC548, BC549 and BC550 are NPN types, while BC556, BC557, BC558, BC559 and BC560 are PNP types and form complementary pairs with the NPN type. Some headphones are 8 ohms per ear and are 4 ohms when in parallel. You may refer to the article 100 Watt transistor amplifier to see an example of the role of complementary transistor pairs in making a particular circuit more efficient. The general-purpose range of transistors is a good substitute for basic non-critical audio applications, as these transistors are similar and equivalents to each other. Can I use a Transistor BC547 instead of BC548? On the other hand, 2N3904 is originated from the United States of America and is the most popular general-purpose transistors in the world. Half the 1.5V battery across 4 ohms results in a current in the output transistor of 188mA. BC549 has a decent gain value hfe from 420 to 800; this value determines the amplification capacity of the transistor. For a better experience, please enable JavaScript in your browser before proceeding. You are probably using MOSFET in the portable battery-operated applications which require a very low power loss. Copyright © 2020 WTWH Media, LLC. A TIP127 is a high voltage PNP power darlington transistor that is completely different from the NPN BC337 transistor. Register now to get updates on promotions and coupons. These transistors are utilised in audio frequency, and small signal directly coupled preamplifiers. BC549 SMD. Wiki 2N2907 vs 2N3906 2N2907 and 2N3906 are both... BC337 BC338 BC327 BC328 SMD Equivalent is BC817 BC818 BC807 BC808 The transistor part number nomenclature are JIS, Pro Electron, and JEDEC. Copyright 2020 © Components101. 2N2907 vs 2N2222 2N2907 is PNP complementary of 2N2222 NPN transistor in a TO-18 package. When the base current is removed the transistor will be fully off, this step is called  Cut-off Region. Features Switching and Amplifier With the proliferation,... 2N2907 vs 2N2222 and 2N2907 vs 2N3906 Whenever you search for 2N2907, Google will suggest that 2N2907 vs 2N2222 and 2N2907 vs 2N3906 are popular searches. If you are designing a PCD or Perf board with this component then the following picture from the Datasheet will be useful to know its package type and dimensions. The ZTX series came in an E-Line (TO-92) package formed by injection moulding silicone plastic to provide a rugged encapsulation. You can use BC546 to replace BC547 and BC548, but cannot replace BC549 and BC550 which are screened for low noise applications. And BC547 should be able to handle over 200mA Ic because the current rating is mainly dependent on the package (TO-92) itself. May 19, 2020 These transistors are utilised in audio frequency, and small signal directly coupled preamplifiers. collector current (output current in common emitter config): 2N2222A - 600mA. The Complement of this transistor is: BC557, BC558, BC559, Bc549 transistor substitute, alternate and equivalent are:BC548, 2N2222, 2N3904, BC550, C945, PN100, BC337, There is a list of SMD alternate of To-92. As you can see from this, the largest current gain is available from group C that is why the BC549C is more commonly used. BC547 is originated from Europe and BC547/548 are the most popular general-purpose transistors for the European consumer electronic design. When the transistor is fully biassed then it can permit a max of 100mA to flow across the collector and emitter so This step is called Saturation Region. BC549 has a reasonable gain value (HEF) from 420 to 800; this value controls the amplification capacity of the transistor. You are probably using MOSFET in the portable battery-operated applications which require a very low power loss. 2N3904 2N3906 2N4401 2N4403 2N5401 2N5551 SMD Equivalent, BC337 BC338 BC327 BC328 SMD Equivalent, BC547 with Vceo of 45V rating while 2N3904 is just 40V, 2N3904 with Ic of 200mA rating while BC547 is just 100mA. Both transistors have a maximum collector-emitter rating of 30 V, and collector-base rating of 30 V. The main difference is that BC549 is a special low-noise type and available in groups B and C only, whilst BC548 is more general-purpose type and available in all three groups A, B, and C. Due to the similarities between a BC548 and BC549, they are interchangeable within many low voltage non-critical circuits, and therefore considered equivalents. The pin configuration of BC549. The author was the global business manager of the Discrete division of National Semiconductor in Silicon Valley in the late ’80s. The general-purpose range of transistors is a good substitute for basic non-critical audio applications, as these transistors are similar and equivalents to each other. Compnents, Transistors When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter. I calculated the bias point of the preamp transistor with a good hFE of 505, a low hFE of 109 and a high hFE of 807. admin The complimentary version has identical characteristics except it is a PNP type. BC546 vs BC547/BC549 Fairchild Datasheet tells you all about BC54x family of transistors High Voltage: BC546, VCEO=65V Low Noise: BC549, BC550 VCEO Collector-Emitter Voltage : BC546 : 65V BC547/550 : 45V BC548/549: 30V BC546/547/548/549/550 is made from the same process (the same silicon die) but just different screening based on different parameters.

Both devices are used mainly as a general-purpose transistor for low voltage and low current designs. The BC548 and BC549 are almost identical NPN transistors. The author was the global business manager of the Discrete division of National Semiconductor in Silicon Valley in the late ’80s. BC549 is a low current transistor so the max amount of current that could flow through the Collector pin (Ic) is 100mA, so we cannot connect loads that use above 100mA and load voltage above 30volt using this transistor. Maximum Storage and Operating temperature Should Be. BC549 equivalent . The most noticeable difference is in the packaging and pin configuration. BC546 is unique for high voltage applications. Si nuestro circuito está alimentado por una tensión de 5V, 12V o 24V, podemos usar indistintamente cualquier modelo de la familia sin inconvenientes. A transistor is a device mostly used for switching purposes. BC559 and BC560 . BC549 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. The BC549 is an NPN transistor; however, it also has a complimentary PNP version, which is the BC559. The BC109 package was TO-18 / SOT18 metal canister, whilst the modern BC549 package is a TO-92 / SOT54 plastic material.
