ULN2003 7 Darlington Transistor Arrays SMD IC

The ULN2003 is a versatile 7-channel Darlington transistor array IC available in a Surface-Mount Device (SMD) package, designed to drive high-current and high-voltage loads using low-level logic signals. It contains seven independent Darlington transistor pairs, which offer a high current gain, typically around 1000, enabling each channel to handle a maximum output current of 500mA. The IC can operate at voltages up to 50V, making it suitable for controlling various high-power devices such as relays, stepper motors, solenoids, and other inductive loads. One of the key features of the ULN2003 is its integration of flyback diodes across each output, providing essential protection against voltage spikes when switching inductive loads. This ensures safe operation and prevents damage to the IC. The device is also compatible with TTL and CMOS logic levels, making it easy to interface with microcontrollers, microprocessors, and other digital control systems.
