ULN2003 : SMD/SMT Darlington Transistor Arrays

ULN2003 SMD/SMT Darlington Transistor Array IC

The ULN2003 SMD/SMT Darlington Transistor Array is a high-voltage, high-current integrated circuit designed for robust interfacing. It seamlessly connects low-level logic circuitry with multiple peripheral power loads. Each of its seven drivers offers a continuous load current rating of up to 500 mA. This array can manage significant power loads, typically exceeding 230 W, depending on the duty cycle and ambient conditions. It's perfectly suited for controlling various inductive and resistive loads. All devices feature open-collector outputs complemented by integral clamp diodes for enhanced protection. The ULN2003A/L variant includes series input resistors, making it directly compatible with 5V TTL or CMOS logic. This makes it an ideal solution for complex interface needs that surpass standard logic buffer capabilities.
