Identifying Pins of Power Electronic Devices 1.
Current flows from Anode to Cathode when the Gate gets a positive pulse. Once triggered, the SCR will latch and continue to conduct even if the gate voltage is removed. To switch off it, we have to break the anode current through switch off. Like Transistors, the SCR pins can be identified by keeping the front side towards you.
The Code printed side is the front side. Pin 1 is the main terminal 1, pin 2 is the main terminal 2 and pin 3 is the Gate terminal. In some cases like TRIACs by Siemens, the two terminals which can be seen are gate and cathode, with the shorter one being the gate and the longer one is the cathode. Usually, the device is held such that the flat side is facing toward the person.
The pins are numbered from 1 to 3 starting from left to right. Pin 1 is the anode, Pin 2 is the Gate and Pin 3 is the cathode.
A practical example is 2N For few UJTs like 2N, holding the device such that the pins are downwards and starting from clockwise direction, the 1st one is the Base1 terminal, the second or the middle one is the Emitter terminal and the third one is the Base2 terminal. There is a projected part in one side which is the front side. Show related SlideShares at end.

Alternatively, the transistor can be used to turn current on or off in a circuit as an electrically controlled switch , where the amount of current is determined by other circuit elements.
There are two types of transistors, which have slight differences in how they are used in a circuit. A bipolar transistor has terminals labeled base, collector, and emitter.
A small current at the base terminal that is, flowing between the base and the emitter can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor , the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.
The image represents a typical bipolar transistor in a circuit. Charge will flow between emitter and collector terminals depending on the current in the base. Because internally the base and emitter connections behave like a semiconductor diode, a voltage drop develops between base and emitter while the base current exists.
The amount of this voltage depends on the material the transistor is made from, and is referred to as VBE. Transistor as a switch[ edit ] BJT used as an electronic switch, in grounded-emitter configuration. Transistors are commonly used in digital circuits as electronic switches which can be either in an "on" or "off" state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.
Important parameters for this application include the current switched, the voltage handled, and the switching speed, characterised by the rise and fall times.
In a grounded-emitter transistor circuit, such as the light-switch circuit shown, as the base voltage rises, the emitter and collector currents rise exponentially.
The collector voltage drops because of reduced resistance from collector to emitter. If the voltage difference between the collector and emitter were zero or near zero , the collector current would be limited only by the load resistance light bulb and the supply voltage.
This is called saturation because current is flowing from collector to emitter freely. When saturated, the switch is said to be on. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal.
The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.
