ULQ2003D1013TR

Overview

The ULQ2003D1013TR is a high-voltage, high-current Darlington array manufactured by STMicroelectronics. It integrates seven open-collector Darlington pairs with common emitters within a single package. Each channel supports a maximum continuous collector current of 500 mA and can withstand peak currents up to 600 mA. The device features an output voltage rating of 50 V and includes integrated suppression diodes for driving inductive loads. Inputs are pinned opposite outputs to simplify printed circuit board layout. The component operates within a temperature range of -40 °C to 125 °C and is supplied in a 16-pin SOIC surface-mount package.

Feature Summary

• Integrates seven independent Darlington pairs with common emitters for versatile load driving
• Includes built-in suppression diodes specifically designed for inductive load protection
• Features input-output pin opposition to facilitate simplified printed circuit board layout
• Compatible with TTL, CMOS, PMOS, and DTL logic families for broad interface support

Applications

• Driving solenoids and relays
• Controlling DC motors
• Powering LED displays
• Operating filament lamps
• Driving thermal print-heads

Procurement Notes

Verify the specific suffix 'D1013TR' against official STMicroelectronics documentation to confirm the SOIC-16 surface mount package and automotive grade qualification status. Ensure the ordering code matches the required temperature range and packaging format before procurement.

Selection Notes

Select this component when multiple high-current switching channels are required from a single logic source. The integrated diodes eliminate external flyback components for inductive loads. Verify that the 500 mA per channel limit meets the specific load requirements and that the 50 V breakdown voltage is sufficient for the application supply voltage.

Part Context

This part belongs to the ULQ200x series of Darlington arrays, which also includes variants like ULQ2001 and ULQ2004. These devices share similar internal architectures but may differ in specific electrical characteristics or pin configurations. The ULQ2003 variant is specifically noted for its automotive grade availability in the SO16 package.

Replacement Considerations

Direct substitutes include ULN2003A and ULQ2003D1. Verify pin compatibility and electrical ratings such as Vceo and Icmax before substitution. Other family members like ULQ2001D1013TR may require schematic adjustments due to different internal transistor configurations.
