MPSA42 Transistor Explained / Description:

MPSA42 is an NPN BJT transistor designed for high voltage applications such as high voltage switching and high voltage amplifications. The collector-emitter voltage of the transistor is 300V which makes it ideal to use in applications in which a general purpose BJT transistor can’t be used because most of the normal general purpose BJT transistor have the max collector-emitter voltage of 100V. Moreover the 300V collector-emitter voltage feature can also make it reliable to use in circuits where there is a risk of sudden voltage fluctuations.



Where We Can Use it & How to Use:

MPSA42 can be used in high voltage applications such as Telephonic applications, video applications, communications etc. Other than that this transistor can also be used for high voltage switching purposes unlike any general purpose transistor. If used as a switch it can drive load of upto 500mA which makes it capable to control relays, LEDs, high power and medium power transistors etc. Moreover it can also be used as an amplifier in variety of audio related application such as in audio amplifiers and audio amplifier stages.



Inverter Applications

UPS Circuits

High Voltage Power Supplies

Battery Charger Circuits

Audio Amplifiers

Audio Amplifier Stages

Motor Controllers

DC High Voltage Switching


How to Safely Long Run in a Circuit:

To make this transistor perform better and long term in your circuits it is suggested to not drive load of more than 500mA and load voltage cannot be increased more than 300V. Always use a suitable base resistor and do not store or operate in temperature above +150 centigrade and below -55 centigrade.
