Download free 2n39046/18/2023 ![]() pulse width modulation(pwm), because of its fast switching speed. It's also used in fast switching applications i.e.It's normally used as a simple switch to control heavy loads, because of its low saturation voltage and high gain.Few of 2N3904 applications are as follows: Now, let's have a look at few applications of 2N3904:ĢN3904 is one of the most commonly used NPN transistor because of its low-cost, high-speed and small-size. If current/voltage passing through a transistor exceeds its ratings, the transistor may burnt out.So, a circuit designer's task is to select an optimized transistor for its circuit, which should fullfill all its power equirements & must be cost efficient.Transistors are available in different ranges of power ratings and their selection depends on circuit's requirements.Now let's have a look at poewr ratings of 2N3904: Let's have a look at the equivalents of 2N3904 NPN Transistor:Īlthough common transistors such as 2N3904 are easily available in local/online electronics stores, but its wise to know the alternatives. Here's the link to download 2n3904 Datasheet: In order to get in-depth knowledge on any component, must read its datasheet.Let's have a look at the Datasheet of 2N3904: 2N3904 Pinouts alongwith their symbols are shown in the table given below.2N3904 Pin Diagram is shown in below figure:.used in televisions, home appliances, medium-load switches, PWM applications etc. It has a wide range of applications i.e.Small voltage at base(around 0.7V) changes its state from reverse to forward biased and starts conducting.As it's an NPN transistor, so major charge carriers are electrons caryying negative charge.2N3904 is a silicon NPN Bipolar Junction Transistor (BJT), enclosed in TO-92 package and is normally used for switching & amplification purposes.
