• BC548 abstract "The BC548 is a general purpose epitaxial silicon NPN bipolar junction transistor found commonly in European electronic equipment, and part of an historically significant series of transistors that began in 1966 with Philips' introduction of the BC108 and its high-voltage BC107 and low-noise BC109 variants. The BC107/8/9 devices became the most used transistors in Australia and Europe, and subsequent members of the series in plastic packages (such as the BC547, BC548 and BC549) retained the specifications of the metal-cased BC107/8/9 essentially unchanged except for improvements - in thermal resistance and reliability for example.The part number is assigned by Pro Electron, which allows many manufacturers to offer electrically and physically interchangeable parts under one identification. The BC548 is commonly available in European Union countries. It is often the first type of bipolar transistor young hobbyists encounter, and is often featured in circuit diagrams and designs published in hobby electronics magazines.BC548 is one of a series of related transistors: BC546 to BC550. These have broadly similar ratings and the same collector current and hfe, but their breakdown voltage ratings VCEO and VCBO vary across the range. -548 has a 30V VCBO, the -547 50V and the -546 80V. The -549 and -550 variants are low-noise versions.The pinout for the TO-92 package used for the BC546 to BC560 has pin 1 (the leftmost pin in the diagram above, i.e. when the flat face of the package faces the viewer with leads at the bottom) attached to the collector, pin 2 connected to the base, and pin 3 connected to the emitter. Note that not all transistors with TO-92 cases follow this pinout arrangement.".
