The ULN2803A is a high-voltage, high-current Darlington transistor array from Texas Instruments. This device features eight NPN Darlington pairs, each rated for 500 mA collector current and 50 V output voltage. Integrated common-cathode clamp diodes are included for switching inductive loads.
The ULN2803A is designed for applications such as relay drivers, hammer drivers, lamp drivers, and display drivers. Each Darlington pair includes a 2.7 kΩ series base resistor, allowing direct operation with TTL or 5V CMOS logic devices. The array is housed in an 18-SOIC package suitable for surface mounting.
Key electrical characteristics include a 50V output voltage and a 500mA collector current per output. The Vce saturation is a maximum of 1.6V at 500µA input current and 350mA collector current. The operating temperature range is -40°C to 85°C.
This component is well-suited for applications requiring the driving of higher current loads from low-current logic signals. Its integrated protection diodes and base resistors simplify circuit design.
