TRANSISTOR 2N3904 SERIES

When the switch is closed, the base of the transistor is biased, and current flows to the base of the transistor. Due to this, 2N3904 remains in the cut-off state and the LED does not glow. NPN Silicon Transistor, 2N3904 Datasheet, 2N3904 circuit, 2N3904 data sheet : KODENSHI, alldatasheet, Datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs and other semiconductors. And no current flows to the base of the transistor. When the switch is open, the base of the transistor is not biased. The required resistor value can be easily calculated using Ohm’s law. Proper biasing of the base ensures adequate base current to turn ON the transistor.Ī resistor of 220 Ohm is connected between the load(LED) and the collector terminal to protect the LED from overcurrent.

This is why a resistor is connected in series with the base pin. The current at the base pin should me 5mA maximum more than it will destroy the transistor. When we provide the required amount of current at the base pin, the transistor will be an open switch when it is forward biased and it will e a closed switch when it is reverse biased. When a transistor is working as a switch, it works on two modes saturation region and cut off the region as explained earlier.

Operating Temperature (To) -55 to 155 C.

Maximum Collector-Base Voltage (Vcb) 60V.

Maximum Collector-Emitter Voltage (Vce) 40V.

2N3904 usually used for the purpose of amplification and fast switching.When it acts as a switch, maximum current it can support is 100mA while acting as an amplifier, the maximum frequency it can support is 100Mhz.ĢN3904 NPN Specifications and Features 参数 When the current through the base is removed, the transistors are fully off at that time this mode is called as cut off region.

When the transformer is wholly biased it allows full current to pass through emitter and collector that is 200mA. When transistor is being used as a switch it operates in two modes cut off region and saturation region. Amplifier 2N3904 Description This device is designed as a generalpurpose amplifier and switch. We have to supply current to the base pin to bias the transistor and this current value should be restricted to 5mA. Thus we can not use this transistor for loads which consumes more than 200mA. The maximum amount of current which can flow through collector pin is 200mA. The amplification capacity of the transistor is determined by the gain value of NPN transistor which is 300 for 2N3904. In 2N3904, when the base pin is grounded the emitter and collector will be opened which is known as reverse-biased while the emitter and collector will be closed when the signals will be transferred to the base pin this is known as forward biased. Secondly Im not sure if I understand the Transistor correctly either. It is a type of Bipolar Junction Transistor BJT as it is a current-controlled transistor. Hi Guys, Im attempting to test a 2N3904 Transistor with an Arduino UNO R3, for starters I believe I havent coded the program correctly. It has three terminals Emitter, Base and Collector. 2N3904 is an NPN transistor which is used for general purpose including switching and amplification.
