The BC is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. It is notably often the first type. Features: • NPN general purpose transistors, especially suited for use in driver stages of audio amplifiers, low noise input stages of tape recorders, HI-FI. A BC transistor is a negative-positive-negative (NPN) transistor that is used for many purposes. Together with other electronic components, such as resistors, .

Devices registered to this Pro Electron number must have the following minimum performance characteristics: BC is NPN type i.

Is this an OK application for a transistor? Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Interface GPS with Arduino.

Choosing the right transistor for a switching circuit – Electrical Engineering Stack Exchange

Complete Technical Details can be found at the datasheet give at the end of this page. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.


To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Still have a question?

See for yourself how vulnerable you are. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Retrieved 17 March Submitted by admin on 30 August Arrays are commonly used in digital switching.

As mentioned the biasing current should maximum of 5mA. It is a current activated device.

So a BC might have a current gain anywhere between andbut the gain of a BCA would be within the range of to Sign up or log in Sign up using Google. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. Please help improve this article by adding citations to reliable sources.

A short vertical line, which is the base, can indicate the transistor schematic for an NPN traneistor, and the emitter, which is a diagonal line connecting to the base, is an arrowhead pointing away from the base.

How does transistor BC work? – Quora

One goal is to keep the components from burning up, while another is to make the circuit work. This group of NPN transistors share many specifications and characteristic curves, but differ in voltage ratings – the BC and BC are essentially the same as the BC transustor selected with higher breakdown voltageswhile the BC is a low noise version, and the BC is both high-voltage and low-noise.


You dismissed this ad. I have found various calculations to determine what kind of transistor I need and I’m not quite sure which is the best one.

Transistor mainly acts as a switch that may be any transistor Thus acting as switch it help in generation of logic i. I understand tfansistor the circuit changes, active high instead of active low, but are there any drawbacks to PNP over NPN?
