ULQ2003D1013TRY

Overview

The ULQ2003D1013TRY is a high-voltage, high-current Darlington array manufactured by STMicroelectronics. It contains seven open-collector Darlington pairs with common emitters, each channel rated for 500 mA continuous current and capable of withstanding 600 mA peak currents. The device operates with an output voltage of 50 V and includes integrated suppression diodes for inductive load driving. Inputs are pinned opposite outputs to simplify board layout and interface with TTL, CMOS, PMOS, and DTL logic families. This specific variant is supplied in a small outline package (SO16) as indicated by the 'D' suffix.

Feature Summary

• Seven Darlington pairs per package with common emitters
• Integrated suppression diodes for inductive loads
• Automotive Grade qualification in SO16 package
• Extended temperature range from -40 to 105 °C

Applications

• Driving solenoids and relays
• Controlling DC motors
• Powering LED displays and filament lamps
• Thermal print-head actuation
• High power buffering

Procurement Notes

Verify the ordering code matches the required package type and automotive grade specification. Confirm the presence of the 'D' suffix indicates the SO16 small outline package variant rather than the standard DIP-16. Ensure the supplier provides documentation confirming AEC-Q100 qualification if automotive application is intended. Check that the reel quantity aligns with production requirements without assuming standard packaging metrics.

Selection Notes

Select this component when driving multiple inductive loads such as relays or solenoids from low-current logic inputs. The integrated flyback diodes eliminate the need for external protection components. Choose the SO16 package version for surface-mount assembly constraints. Verify input compatibility with the system's logic family, as the device supports TTL, CMOS, PMOS, and DTL standards.

Part Context

The ULQ2003 belongs to a family of high-voltage Darlington arrays including the ULQ2001 and ULQ2004. These devices share similar internal architectures but may differ in pinout configurations or specific electrical characteristics. The ULQ2003D1013TRY represents the surface-mount SO16 variant of the commercial ULQ2003, offering thermal resistance reduction through a copper lead-frame construction compared to traditional plastic DIP packages.

Replacement Considerations

Direct substitutes include the ULQ2003D1 and ULQ2004D1 variants within the same STMicroelectronics portfolio. Other manufacturers offer compatible Darlington arrays, but pinout and electrical parameter verification is required. Ensure any replacement maintains the 500 mA per channel rating and integrated suppression diode functionality.
