Frequently asked questions
What is the price of MPSA12 NPN Darlington Transistor TO-92 in Egypt?
MPSA12 NPN Darlington Transistor TO-92 currently costs 2.5 EGP in Egypt.
Where can I buy MPSA12 NPN Darlington Transistor TO-92 in Egypt?
MPSA12 NPN Darlington Transistor TO-92 is available from Makers Electronics. Compare the offers above to find the best price.
Can the MPSA12 drive a relay directly from a microcontroller pin?
It can switch a small relay or LED when the base is driven through a series resistor from the microcontroller pin. Keep the collector current within 500 mA, and place a flyback diode across any relay coil to protect the transistor.
How do I confirm the pinout of the TO-92 package?
TO-92 transistors do not all use the same lead order, so check the pinout (Emitter, Base, Collector) in the datasheet for the MPSA12 before wiring. Hold the flat face toward you with the leads pointing down to read the standard layout.
