ULN2003 : SMD/SMT Darlington Transistor Arrays

ULN2003 SMD/SMT Darlington Transistor Array IC - 7-Channel High-Current Driver

The ULN2003 SMD/SMT Darlington Transistor Array IC is a versatile, high-voltage, high-current integrated circuit. It's engineered for robust interfacing between low-level logic and various power loads. Each of its seven drivers can handle a continuous load current of up to 500 mA. This array efficiently manages significant power loads, making it ideal for inductive and resistive applications. Integrated clamp diodes provide enhanced protection for transient-sensitive outputs. The ULN2003A/L variant features series input resistors, ensuring direct compatibility with 5V TTL or CMOS logic. It's a perfect solution for complex interface needs beyond standard logic buffers. Available in compact SMD/SMT packages, it's designed for modern electronic designs.
