ULN2003AD
Detailed Description
High-performance NPN Darlington transistor array featuring seven independent drivers. This surface-mount component offers a 50V collector-emitter breakdown voltage and a maximum collector current of 500mA per channel. Designed for automotive applications with AEC-Q100 qualification, it operates within a -20°C to 70°C temperature range and is housed in a 16-pin SOIC package. Key specifications include a 1.1V collector-emitter saturation voltage and 25W maximum power dissipation.
