As mentioned the biasing current should maximum of 5mA.

MPSA42 is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin. Top menu About Us Advertise. So if you are looking for an NPN transistor that could switch high voltages mpssa42 a decent current flow then the MPSA42 transistor might be the right choice.

A transistor can normally be used as a switch or amplifier, but this transistor is commonly is used only for switching purpose since it has a low gain value of As discussed a transistor will act as an Open switch during Forward Bias and as a closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.

Also note that the collector current of the IC is mA 0.

The value of this resistor RB can be calculated using below formulae. To bias a transistor we have to supply current to base pin, this current IB jpsa42 be limited to 5mA.

MPSA42 NPN Transistor

The maximum amount of current that could flow through the Collector pin is mA, hence we cannot drive loads that consume more than mA using this transistor. Also note that the operating current of the motor is just 0.

When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. It has a gain value of 30; this value determines the amplification capacity of the transistor normally MPSA42 mpaa42 not be used for amplification due to its low gain value.

The MPSA42 can turn on or turn off high voltage loads upto V hence they are commonly used for heavy loads or loads that have high peak voltage. Next Article Timer IC. If you are designing a PCB or Perf board with this component then the following picture from the MPSA42 transistor Datasheet will be useful to know its package type and dimensions.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. MPSA42 transistor is normally used to switch high voltage loads or loads that have high peak voltages.

Top menu About Us Contact. It has a Base-Emitter voltage of 6V hence it can be controlled easily using microcontrollers or other digital electronics. If 0V is supplied to base pin no current flows to base and thus the transistor is reversed biased making the motor to stop. Anything more than 5mA will mpsa442 the Transistor; hence a resistor is always added in series with base pin.

Skip to main content. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.
