Frequently asked questions
What is the price of MMBT2222A NPN General-Purpose SMD Transistor 40V 600mA SOT-23 in Egypt?
MMBT2222A NPN General-Purpose SMD Transistor 40V 600mA SOT-23 currently costs 1.25 EGP in Egypt.
Where can I buy MMBT2222A NPN General-Purpose SMD Transistor 40V 600mA SOT-23 in Egypt?
MMBT2222A NPN General-Purpose SMD Transistor 40V 600mA SOT-23 is available from UGE and Makers Electronics. Compare the offers above to find the best price.
What is the pinout of the MMBT2222A in SOT-23?
Pin 1 is the Base, pin 2 is the Emitter and pin 3 is the Collector. The top marking on the package is typically 1P.
How much base drive is needed to switch a 150 mA load fully on?
The saturation voltage in the datasheet is specified at 150 mA collector current with 15 mA base current, so about 15 mA of base drive is a good reference for that load. Use a base resistor to set this current from a microcontroller pin, and keep total power within the 250 mW limit.
