Frequently asked questions
What is the price of MMBT3904LT1G NPN Transistor 40V 200mA SOT-23 SMD in Egypt?
MMBT3904LT1G NPN Transistor 40V 200mA SOT-23 SMD currently costs 2 EGP in Egypt.
Where can I buy MMBT3904LT1G NPN Transistor 40V 200mA SOT-23 SMD in Egypt?
MMBT3904LT1G NPN Transistor 40V 200mA SOT-23 SMD is available from Makers Electronics. Compare the offers above to find the best price.
How do I use the MMBT3904LT1G as a switch for a load?
Connect the load between the supply and the collector, feed the base through a resistor from the microcontroller pin, and connect the emitter to ground. Size the base resistor so the transistor is fully saturated for the load current.
Can it switch a 12V relay or motor directly?
Only for loads within its limits. The collector current is rated at 200 mA and the collector-emitter voltage at 40 V, so check the coil or motor current first. For inductive loads such as relays, add a flyback diode across the load.
