Ham Radio Store Choosing Transistor Replacements When repairing a circuit, or even building a new one it is often not possible to find the exact electronics component - we tell you how to choose a suitable replacement. Either the type of transistor may not be to hand, or it may not be available. Fortunately it is normally possible to use a replacement transistor type as there is often a considerable degree of overlap between the specifications of different types of transistor, and by looking at the basic specifications it is normally possible to choose the correct transistor replacements. This explanation is focussed on bipolar transistors, but it is possible to apply similar logic to other electronic components including field effect transistors to ensure that suitable replacements can be found.

BC has a gain value of to , this value determines the amplification capacity of the transistor. 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 IB should be limited to 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. As discussed a transistor will act as an Open switch during Forward Bias and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.

As mentioned the biasing current should maximum of 5mA. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. The value of this resistor RB can be calculated using below formulae. The value of IB should not exceed mA. It can amplify power, voltage and current at different configurations. Some of the configurations used in amplifier circuits are Common emitter amplifier Common base amplifier Of the above types common emitter type is the popular and mostly used configuration.

Amplifier modules like Audio amplifiers, signal Amplifier etc.. Darlington pair 2D model of the component 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. Component Datasheet.
