MPSA92 Transistor Explained / Description
MPSA92 is a general purpose PNP bipolar junction transistor that is specially designed for high voltage applications. The transistor is available in many different packages by few manufacturers while few others only manufacture’s it in TO-92 package. The maximum collector to emitter voltage of the transistor is -300V this feature makes this transistor unique as compare to other general purpose BJT transistors. Moreover the maximum collector current of the transistor is -200mA and some manufacturers also manufacture it with upto -500mA collector current. The maximum collector dissipation of 625mW also makes it ideal to use for audio amplification purposes.
Where We Can Use it & How to Use
As mentioned above MPSA92 transistor is designed for high voltage applications therefore one can use it in any high voltage circuitry under -300V. When used as a switch it can drive load of upto -200mA to -500mA thus it can drive many loads in circuits such as relays, LEDs, high power transistors, ICs etc. Other than that it can also be used in as an audio amplifier separately or also in audio amplifier stages. The maximum transition frequency of 50MHz due to which it can also be used in RF applications under 50MHz.

How to Safely Long Run in a Circuit
To get long term performance with MPSA92 transistor it is suggested to always use the transistor atleast 20% below from its maximum ratings. The maximum collector to emitter voltage of the transistor is -300V therefore do not drive load of more than -240V. If your purchased device has -200mA collector current then do not drive load of more than -160mA and if the collector current is -500mA then the load should not be increased from -400mA. The storage and operating temperature of the transistor should be under -55 degree Celsius to +150 degree Celsius.
