The STMicroelectronics ULN2003D1 is a high-voltage, high-current Darlington transistor array designed specifically for driving inductive loads. It comprises seven NPN Darlington pairs, each capable of sourcing up to 500mA from a 50V supply. The integrated suppression diodes across each output are crucial for protecting the driving circuitry from back EMF generated when switching inductive loads such as relays, solenoids, and stepper motors. Its SO-16 (Small Outline) SMD package allows for dense PCB layouts, making it ideal for space-constrained applications. The ULN2003D1 operates reliably across a temperature range of –20°C to 85°C. Utilizing this IC significantly simplifies circuit design by reducing component count and improving reliability in applications requiring high-current switching.
