The STMicroelectronics ULQ2003A is a versatile 7-channel NPN Darlington transistor array. This component is designed for applications requiring high voltage and current switching capabilities, with a maximum operating voltage of 50V and a continuous current rating of 500mA per channel.
Key electrical characteristics include a high DC current gain (hFE) of 1000 at 350mA and 2V, and a Vce saturation voltage of 1.6V maximum at 500µA and 350mA. The device operates at junction temperatures up to 150°C.
Packaged in a standard 16-DIP format, the ULQ2003A is designed for through-hole mounting, making it suitable for various prototyping and production environments. Its Darlington configuration provides high gain, simplifying drive requirements for loads such as relays, solenoids, and incandescent lamps.
This transistor array is a reliable choice for applications needing to interface low-logic-level signals with higher power loads, offering robust performance and ease of integration into electronic circuits.
