2N3704_D74Z

2N3704_D74Z is a NPN Small silicon general purpose transistor. This small device is a versatile building block when integrated with other electronics components, and it can be used for a wide variety of applications. The 2N3704_D74Z transistor is classified as a single bipolar junction transistor, which functions as a three-terminal active semiconductor device.

In terms of its application field, the 2N3704_D74Z general purpose transistor is typically used for many kinds of small-signal, low-power applications such as small audio amplifiers, LED driver circuits, and lower voltage (0-14V) switching functions. Additionally, this transistor can be used with various other components such as resistors, capacitors, and transistors to enable more complex integrated circuits such as inverters, differential amplifiers, logic gates, and more.

The 2N3704_D74Z operates according to the conventional three-terminal bipolar junction transistor (BJT) circuit technology. This BJT type transistor is a voltage-controlled device and consists of emitter, collector, and base terminals. Positive voltage is applied across the base and emitter terminals to control the current flow between the collector and emitter.

Because the forward base-emitter and reverse base-emitter resistances are very low, the base current is much lower than the collector current, making it an ideal transistor for current amplification. The E and C are equivalent to the collector and emitter respectively. When the base is given a positive voltage, the current present in the emitter and the collector can be controlled. When the base-emitter voltage is relatively low (around 0.6 - 0.7 V), the transistor will be in the cutoff state, where the collector current is practically zero. In order to have significant output current, the voltage between the base and emitter has to be higher than 0.7 volts. If a higher voltage is applied, the transistor will be in the saturation state, i.e. the collector current is at its maximum value.

Thus, by controlling the emitter and collector currents of the 2N3704_D74Z, this transistor can be used for a wide variety of applications such as audio amplifiers, voltage regulators, switching and interface circuits. With the help of various other semiconductor devices, this transistor can also be used to develop larger and more complex integrated circuits.
