![]() ![]() Normal transistor have a current gain for around 100-300 but our Darlington transistor has a gain of 20000 hence it can be easily used in amplifier applications. The 2N5306 transistor is very much similar to the commonly used NPN transistors, but it is way more powerful than those since it is a Darlington transistor. Where to use 2N5306 Darlington Transistor? This is exactly where a Darlington transistor comes in. But in some application, the base current will be limited and cannot be increase during which we have to increase the transistor gain. So for loads consuming high power it becomes mandatory to increase the base current. Load current=i/p current X transistor gain As we know a transistor is turned on by providing an input current to the base pin (current controlled device) and when it turns on it allows the load current to flow through it which can be given by the formulae It decides how much times the load current can be amplified based on the input current to the bias pin. The current gain is an important property for a Darlington transistor. What is Current Gain? Why is it important? For example the transistor here has a current gain of 20000 and a collector continuous current of 1.2A because of its Darlington properties. ![]() One very important function of a transistor is its very high current gain. Yes the transistor you see above is actually a combination of two transistors provided in a single package to make it easy to use in our circuits. Out of which one transistor will be an NPN transistor and the other will be a PNP transistor. The Darlington Transistors are made up of two transistors combined togather. Collector-Emitter voltage (VCE) is 25 V.Continuous Collector current (IC) is 1.2A.High DC Current Gain (hFE), typically 20,000 when IC=100mA.Current Drains out through emitter, normally connected to groundĬontrols the biasing of transistor, Used to turn ON or OFF the transistorĬurrent flows in through collector, normally connected to load ![]()
