ULN2803A Darlington Transistor Arrays
1 Features
3 Description
•
The ULN2803A device is a 50 V, 500 mA Darlington
transistor array. The device consists of eight NPN
Darlington pairs that feature high-voltage outputs with
common-cathode clamp diodes for switching
inductive loads. The collector-current rating of each
Darlington pair is 500 mA. The Darlington pairs may
be connected in parallel for higher current capability.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, unless otherwise noted, are with respect to the emitter/substrate terminal GND.
