About this product
A high-voltage NPN bipolar transistor in a TO-92 package, rated for collector-emitter and collector-base voltages up to 300 V and a continuous collector current of 500 mA. It suits high-voltage switching and driver stages in hobby circuits where standard low-voltage small-signal transistors are not enough.

Frequently asked questions
What is the price of MPSA42 High-Voltage NPN Transistor TO-92 in Egypt?
MPSA42 High-Voltage NPN Transistor TO-92 currently costs between 2 and 5 EGP across 2 offers in Egypt.
Where can I buy MPSA42 High-Voltage NPN Transistor TO-92 in Egypt?
MPSA42 High-Voltage NPN Transistor TO-92 is available from Makers Electronics and Microohm. Compare the offers above to find the best price.
Is MPSA42 suitable for low-voltage switching?
It works, but for low-voltage logic-level switching a small-signal NPN such as BC547 or 2N3904 is usually simpler. The MPSA42 advantage is its 300 V rating.
What is the pin order on the TO-92 package?
The listed order is pin 1 Emitter, pin 2 Base and pin 3 Collector, which is E-B-C. Check the flat side of the case and confirm the orientation against the datasheet before wiring.
