About this product
The MPSA94 is a PNP high-voltage transistor in a TO-92 plastic package, intended for high-voltage switching and driver stages. It is used in interface and amplifier circuits where the collector must withstand voltages above the range of standard general-purpose transistors. Check the datasheet for the complete ratings.

Frequently asked questions
How does the MPSA94 compare with the MPSA92?
Both are PNP high-voltage devices in TO-92. The MPSA94 is rated for a higher collector-emitter voltage than the MPSA92. Choose based on the maximum voltage in your circuit and confirm current ratings in the datasheet.
What precautions are needed when using a high-voltage PNP transistor?
Keep the collector-emitter voltage well below the rated maximum, use appropriate base current limiting, and ensure adequate insulation and spacing on the PCB. Use fuses or current limits when experimenting.
