Product Description
Texas Instruments ULN2003AID 7-Darlington NPN Transistor Array comes in a 16-pin SOIC package designed for surface mounting on printed circuit boards. It is engineered to deliver a maximum continuous collector current of 500 mA and withstand a maximum collector emitter voltage of 50 V, making it ideal for medium to high current driver applications in various industrial and electronic systems.
This Darlington array integrates 7 transistor pairs into a single compact package, which simplifies circuit design and reduces board space. The device exhibits a maximum collector emitter saturation voltage of 1.1 V, ensuring efficient switching with low power loss. The NPN transistor polarity is standard for most control and driver applications.
It operates reliably over a temperature range from -40°C to 105°C, suitable for demanding environmental conditions. The low maximum collector cut-off current of 100 μA minimizes leakage current, enhancing overall circuit efficiency.
This transistor array is widely used in industrial automation, embedded systems, stepper motor drivers, relay drivers, and lamp drivers. Its surface-mount SOIC package allows easy integration in high-volume manufacturing processes with automated pick-and-place assembly.
The 7 transistor pairs provide multiple channels for driving various loads in a compact form factor. Robust switching supports load driving in automotive, industrial, and instrumentation applications. Low saturation voltage reduces heat dissipation and power consumption.
Complies with standard electronic component packaging for efficient PCB layout.
Texas Instruments provides this ULN2003AID device as a new product, designed and made to meet demanding specifications for reliability and performance. Suitable for engineers and manufacturers involved in product development, prototyping, and production to improve system efficiency and control.
