Other alternative options are 2N3906, MPSA55, MPSA90 MPSA42 FeaturesĪll Features of this NPN transistor are mentioned as per the datahseet. This pin is for providing the junction current to output load. This pin is for controlling the current that flow from emitter to collector. This pin is for basing the emitter-base junction The figure below Pinout configuration diagram of MPSA42 NPN Transistor Its pinout configuration is shown in figure 1

It works at dc operating voltage range 30 to 300votls. Because it is an NPN transistor, therefore, current flows from collector to emitter. MPSA42 consists of three basic segments emitter-base and collector. MPSA42 has 300volts emitter to collector voltage. These have a little bit differ specifications and characteristics form each other. The identical family members of this MPSA42 are MPSA42G, MPSA42RL1G, MPSA42RLRAG, and MPSA42RLRAG, etc. It is made of silicon material and easily available in a dip TO-92 package. It is highly adequate with a low collector current amplifier as compared to conventional type amplifiers such as LM741 OP-AMP etc. It is an advanced form of an amplifier with extra over-voltage and breaks down voltage protection property.

MPSA42 is an NPN typically used transistor that has been widely used for high voltage switching and amplification applications.
