ULQ2004D1013TR

Overview

The ULQ2004D1013TR is a high-voltage Darlington transistor array manufactured by STMicroelectronics. It integrates seven NPN Darlington pairs within a single SOIC-16 surface-mount package, providing a continuous collector current of 500 mA per channel and a collector-emitter voltage rating of 50 V. The device features a minimum DC current gain (hFE) of 1000 and a maximum collector-emitter saturation voltage of 1.6 V. Designed for industrial applications, it operates across a temperature range from -20°C to +85°C.

Feature Summary

• Integrates seven independent high-voltage NPN Darlington pairs in a compact surface-mount package
• Provides high current drive capability suitable for direct interfacing with logic circuits
• Includes internal clamping diodes to suppress inductive kickback from load switching

Applications

• Relay driver circuits
• Solenoid control systems
• Lamp driving interfaces

Procurement Notes

Verify the specific manufacturer part number against official STMicroelectronics documentation to confirm pinout compatibility and electrical ratings. Ensure the component meets the required operating temperature range and packaging specifications for the target design.

Selection Notes

Select this component when a multi-channel high-current switching solution is required. The integrated Darlington structure simplifies interface design by eliminating external base resistors. Verify that the thermal dissipation requirements are met within the SOIC-16 package constraints.

Part Context

This component belongs to the ULQ2004 series of high-voltage Darlington arrays. It shares functional similarities with other members of the family but offers specific integration levels tailored for general-purpose high-current switching tasks in industrial environments.

Replacement Considerations

Compatible substitutes include the ULN2003A and ULN2004A series. Verify pinout alignment and ensure the replacement matches the 50 V voltage rating and 500 mA current capacity.
