Frequently Asked Questions
Q: What is the difference between ULN2803AFWG (SOP-18) and ULN2803AP (DIP-18)?
A: The ULN2803AFWG comes in a SOP-18 surface-mount (SMD) package, making it ideal for compact PCB designs and automated assembly. The ULN2803AP/ULN2803APG is a DIP-18 through-hole package, which is easier to use for hand soldering, breadboarding, and prototyping. Both share the same 8-channel Darlington array electrical characteristics.
Q: Can I use these ULN2803 ICs with an Arduino or Raspberry Pi?
A: Yes! The ULN2803 is fully compatible with 3.3V and 5V logic outputs from Arduino, Raspberry Pi, and other microcontrollers. It is commonly used to drive relays, stepper motors, and other higher-current loads that a microcontroller GPIO pin cannot drive directly.
Q: Do these ICs include built-in protection for inductive loads?
A: Yes. Each channel includes an integrated flyback (suppression) diode, which protects your circuit from voltage spikes when switching inductive loads such as relays, solenoids, and DC motors — no external diode needed.
Q: How many pieces are included in this listing?
A: This listing includes 10 pieces of the ULN2803 IC chipset. The pack may include a mix of SOP-18 SMD and DIP-18 through-hole variants as described, giving you flexibility for different PCB designs.
