ULN2003ADR2G

Overview

The ULN2003ADR2G is a high-voltage, high-current Darlington transistor array manufactured by onsemi. It integrates seven NPN Darlington-connected transistors with internal suppression diodes and 2.7 kΩ series input resistors in a single SOIC-16 package. The device supports continuous collector currents up to 500 mA and withstands output voltages of 50 V. Operating ambient temperature ranges from -20°C to +85°C. Electrical characteristics include a DC current gain (hFE) of at least 1000 at 350 mA and 2 V, and a collector-emitter saturation voltage of 1.6 V maximum at 350 mA.

Feature Summary

Integrates seven independent NPN Darlington pairs with built-in 2.7 kΩ base resistors for direct TTL/CMOS logic interfacing.
Includes internal clamp diodes across each output to suppress inductive load voltage spikes.
Provides high breakdown voltage capability suitable for driving heavy inductive loads.

Applications

Driving relays and solenoids
Stepper motor control circuits
Incandescent lamp drivers

Procurement Notes

Verify the component marking code 'AWLYWW' against the datasheet to confirm authenticity. Ensure the package suffix 'R2G' corresponds to the specified tape and reel quantity of 2500 units. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this part when seven isolated high-side switching channels are required within a compact surface-mount footprint. The integrated input resistors simplify driver circuit design by eliminating external components. Verify that the 500 mA per-channel limit meets the specific load requirements of the application.

Part Context

This component belongs to the ULx2003A family of Darlington arrays. It shares functional similarities with the ULQ2003A variant but differs in pin configuration and internal topology. The 'ADR2G' designation specifically identifies the SOIC-16 Pb-free package with tape and reel shipping format.
