As mentioned the biasing current should maximum of 5mA. To participate you need to register. 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.
A Transistors acts as an Amplifier when operating in Active Region. The value of I B should not exceed mA. Submitted by admin on 26 October It can amplify power, voltage and current at different configurations.

There are markings on the back of them that either read: 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. Media New media New comments Search media. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.
BC has a gain value of tothis value determines the amplification capacity of the transistor. Of the above types common emitter type is the popular and mostly used configuration. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin.
Current Drains out through emitter. Amplifier modules like Audio amplifiers, signal Amplifier etc. TL — Programmable Reference Voltage. Replacement Transformer Started by ncag Today at 7: Click here to register now. BC Transistor as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
SP, where the P has a line above it. I have a bunch of transistors that come in two types. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.
Reading Transistor Codes
If you are designing a PCD or Perf board with this component then the following picture from the BC Datasheet will be useful to know its package type and dimensions. You must log in or register to reply here. Controls the biasing of transistor. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. The value of this resistor R B can be calculated using below formulae. Pioneer Elite vsxtx water damage no power Started by Watin Today at Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
Type C into Google.
Welcome to our site! Forums New posts Search forums. Then download the datasheet. Complete Technical Details can be found at the BC datasheet given at the end of this page.
Current flows in through collector. Thread starter inkzoid Start date Feb 15, 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.
