E-ULN2001A Description

Short technical summary and product information.

The E-ULN2001A is a high-current Darlington transistor array containing seven NPN Darlington pairs in a single 16-DIP package. Each pair provides a minimum DC current gain (hFE) of 1000 at 350mA collector current and 2V collector-emitter voltage, enabling efficient switching of inductive loads such as relays, solenoids, and motors.

 

The array is rated for a maximum collector-emitter voltage of 50V and a continuous collector current of 500mA per channel. The collector-emitter saturation voltage is limited to 1.6V at 500µA base current and 350mA collector current, ensuring low power dissipation in saturated switching applications.

 

The device is mounted via through-hole technology into a standard 16-lead DIP (0.300" width, 7.62mm lead spacing) and is capable of operating at junction temperatures up to 150°C. This makes it suitable for industrial and automotive environments requiring robust thermal performance.
