MMBT3904FA-7B

The MMBT3904FA-7B is a single general-purpose NPN transistor manufactured by On Semiconductor. It is designed to be used in audio amplifier circuits and low power applications. The MMBT3904FA-7B has a wide range of operating parameters for many different applications and is ideal for use in low-noise amplifiers, switch circuits, and low power transistor circuits. This is due to its low current requirements, low saturation voltage, and high gain and switching speed.

The MMBT3904FA-7B is a NPN transistor, which means that its base terminal is biased positively relative to its emitter. This will allow current to flow from the emitter to the collector. When a positive voltage is applied to the base, more current will flow through the transistor, allowing it to be used as an amplifying device. As the voltage at the base increases, the gain of the transistor will also increase.

The MMBT3904FA-7B has a maximum collector current of 200mA and a maximum collector-emitter voltage of 45V. It has a minimum current gain of 200 at 1mA collector current and a maximum current gain of 800 at 10mA collector current. It also has a maximum power dissipation of 625mW. The MMBT3904FA-7B has an RON of 100 Ohms and a VBE of 0.7V. The MMBT3904FA-7B has a maximum operating temperature of 175 degrees Celsius.

The MMBT3904FA-7B is designed for use in audio amplifiers and low-power applications.
