Where can I buy ULN2803 SMD 8-Channel Darlington Transistor Array IC in Egypt?
ULN2803 SMD 8-Channel Darlington Transistor Array IC is available from RAM Electronics. Compare the offers above to find the best price.
Can I drive a relay directly from an Arduino pin with it?
Yes. Connect the Arduino pin to one input, and connect the relay coil between the supply and the matching output. Keep the load current under 500 mA per channel and share a common ground between the Arduino and the load supply.
Do I need external flyback diodes for inductive loads?
Not usually. The ULN2803 has built-in clamp diodes on each channel for inductive loads such as relays and motor coils. Confirm the voltage and current ratings in the datasheet for your specific load.
