A 2N3904 made. The pinout from left to right is: Emitter, Base, Collector. The 2N3904 is a common used for general-purpose low-power or switching applications. The type was registered by in the mid-1960s, together with the complementary PNP type, and represented a significant performance/cost improvement, with the plastic TO-92 case replacing metal cans.
It is designed for low and, medium, and can operate at moderately high speeds. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. When looking at the flat side with the leads pointed downward, the three wires emerging from the bottom are connected to, from left to right, the emitter, the base and the collector. Some manufacturers mark 'EBC' on the molded part, but all are required to have those connections for a part which is a '2N3904'. It is a 200, 40, 625 transistor with a of 300, with a minimal, or current gain, of 100 at a collector current of 10. It is used in a variety of analog amplification and switching applications.
The 2N3904 is used very frequently in hobby electronics projects, including home-made, code-practice oscillators and as an interfacing device for. Contents • • • • • Related parts [ ] Electrically similar devices, such as the MMBT3904, are available in a variety of small through-hole and surface-mount packages, including,, and SOT-223, with package-dependent thermal ratings from 625 to 1. The complementary is. The higher-power is a very similar NPN transistor that can safely switch three times as much current as the 2N3904. Nevertheless, in many applications such as variable-frequency oscillators, where lower currents are used to minimize thermal heating and consequent thermal drift of the fundamental frequency, the greater current capacity of the 2N2222 gives it no advantage. Whereas the 2N2222 is optimized to reach its highest gain at currents of around 150 mA, the 2N3904 is optimized for currents of around 10 mA. Part numbers [ ].
Dari diagram aliran arus pada gambar 3.5 dapat diketahui bahwa harga a adalah kurang dari satu, karena arus IE sebagian dilewatkan menjadi IB dan lainnya menuju kolektor menjadi IC. Harga tipikal dari a adalah 0,90 hingga 0,998. Umumnya harga a untuk setiap transistor dicantumkan dalam buku data.

Brattain dan John Bardeen pada akhir Desember 1947 di Bell Telephone Laboratories berhasil menciptakan suatu komponen yang mempunyai sifat menguatkan yaitu yang disebut dengan Transistor. Keuntungan komponen transistor ini dibanding dengan pendahulunya, yakni tabung hampa, adalah ukuran fisiknya yang sangat kecil dan ringan. Bahkan dengan teknologi sekarang ini ratusan ribu transistor dapat dibuat dalam satu keping silikon. Disamping itu komponen semikonduktor ini membutuhkan sumber daya yang kecil serta efesiensi yang tinggi. Pada bab ini akan dibahas struktur transistor bipolar dan karakteristiknya. Pemberian bias yang benar akan dapat menentukan daerah kerja transistor. Beberapa macam konfigurasi transistor juga dikenalkan, sebelum.
