About this product
The MPSA56 is a PNP high-voltage transistor in a TO-92 plastic package. It is used in high-voltage driver and amplifier stages where a PNP device is needed, such as driving the NPN side of a high-voltage output. Check the datasheet for the full voltage and current limits before use.

Frequently asked questions
What is the difference between MPSA56 and MPSA92?
Both are PNP high-voltage transistors in TO-92, but the MPSA92 has a much higher collector-emitter voltage rating. Choose the MPSA56 for moderate voltages and the MPSA92 for higher-voltage stages.
How do I use the MPSA56 as a level-shifting driver?
Connect the emitter to the higher supply and use a base resistor from a control signal. When the base is pulled low, the transistor conducts and pulls the collector toward the supply. Verify the voltage limits in the datasheet against your circuit.
