ULN2003APWR Description

Short technical summary and product information.

The ULN2003APWR from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises seven NPN Darlington pairs, each equipped with common-cathode clamp diodes suitable for switching inductive loads. The device offers a collector-current rating of 500mA per single Darlington pair, with the capability to parallel pairs for increased current handling.

 

Key electrical specifications include a maximum switching voltage of 50V and a peak output current of 0.5A. The input is compatible with CMOS and TTL logic levels, and it features a typical delay time of 250ns. The operating temperature range is from -40°C to 70°C.

 

This transistor array is commonly used in applications such as relay drivers, hammer drivers, lamp drivers, and display drivers (LED and gas discharge). Its output configuration is low-side, and the input type is inverting. The ULN2003APWR is supplied in a 16-TSSOP surface-mount package.

 

Environmental compliance includes RoHS3 compliance and an MSL of 1. The device is designed for reliable operation in various industrial and electronic applications requiring robust output driving capabilities.
