ULN2003D1013TR – STMicroelectronics

The STMicroelectronics ULN2003D1013TR is a high-voltage, high-current Darlington transistor array specifically configured as a sink driver. This SMD device, housed in a compact SO-16 package, features seven NPN Darlington pairs, each capable of sinking up to 500mA of current from a load, with a maximum output voltage rating of 50V. Integrated suppression diodes are included for driving inductive loads like relays, solenoids, and stepper motors, simplifying board layout and improving noise immunity. Its wide operating temperature range of –40°C to 125°C makes it suitable for demanding industrial environments. The ULN2003D1013TR offers a cost-effective and space-saving solution for interfacing low-power logic circuits to higher-power loads, reducing the need for discrete components and simplifying design.
