Product Description
STMicroelectronics ULN2003A is a robust 7-element NPN Darlington Transistor array built for high voltage and current switching capabilities. Rated with a maximum continuous collector current of 500 mA and a maximum collector-emitter voltage of 50 V, this component ensures reliable operation in demanding electronic circuits and industrial control systems. Packaged in a 16-pin PDIP for through-hole mounting, it offers ease of assembly and stable performance across a broad temperature range from -20°C to 85°C.
The transistor array features a high current gain (hFE) of 1000, essential for amplifying weak input signals in driver circuits. It integrates built-in suppression diodes protecting against inductive load back-emf, improving longevity and durability when driving relays, solenoids, and motors. The collector-emitter saturation voltage of 1.1 V further enhances switching efficiency, reducing power dissipation.
The physical dimensions of length 20 mm and height 5.1 mm make the ULN2003A suitable for compact, space-conscious PCB layouts. The inputs are arranged opposite to the outputs within the IC package to facilitate clean and optimized PCB routing. Compatible with standard TTL and CMOS logic levels, it is commonly used in automation, power management, and other electronic applications.
This product is new, directly sourced from STMicroelectronics, and does not currently bear specific industry standards or automotive certifications. It serves well in industrial, laboratory, manufacturing, and electronics prototyping environments requiring reliable transistor switching arrays.
The transistor array supports interfacing and driving multiple relays or loads with a single IC. Integral clamp diodes enhance safety for inductive load switching. High gain and saturation parameters provide efficient signal amplification and power control.
Operating temperature range covers standard industrial conditions. Through-hole PDIP packaging aids prototyping and through-hole PCB assembly. Explore the full range of semiconductor components from STMicroelectronics available at EnvMart for your electronic design and manufacturing needs.
