ULQ2001D1013TR

Overview

The ULQ2001D1013TR is a high-voltage, high-current Darlington array manufactured by STMicroelectronics. It integrates seven open-collector Darlington pairs with common emitters within a single SOIC-16 surface-mount package. Each channel supports a maximum continuous collector current of 500 mA and can withstand peak currents up to 600 mA. The device operates with a maximum collector-emitter voltage (Vceo) of 50 V and features integrated suppression diodes for inductive load driving. It exhibits a minimum DC current gain (hFE) of 1000 and a maximum collector-emitter saturation voltage (VceSAT) of 1.6 V. The component functions within an operating temperature range of -20°C to +85°C.

Feature Summary

• Integrates seven independent Darlington pairs with common emitters for multi-channel switching
• Includes built-in suppression diodes to protect against inductive load back-EMF
• Features input-output pin opposition to simplify printed circuit board layout
• Compatible with TTL, CMOS, PMOS, and DTL logic families

Applications

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

Procurement Notes

Verify the specific suffix 'D1013TR' confirms the SOIC-16 surface-mount packaging and tape-and-reel delivery format. Ensure the procurement specification matches the commercial grade (-20°C to +85°C) rather than automotive or extended industrial variants. Confirm that the supplier provides original manufacturer documentation to validate authenticity and traceability.

Selection Notes

Select this component when multiple low-to-medium power loads require control from a microcontroller or logic gate. The internal suppression diodes eliminate the need for external flyback diodes, reducing bill of materials. Verify that the 500 mA per channel rating meets the peak current requirements of the connected loads. Consider the SOIC-16 package dimensions if space constraints are critical compared to DIP alternatives.

Part Context

This part belongs to the ULQ200x series of Darlington arrays, which includes variants like ULQ2003 and ULQ2004. These devices share similar electrical characteristics but may differ in pinout configurations or specific logic compatibility. The ULQ2001D1013TR represents the commercial-grade surface-mount version, distinct from the through-hole DIP packages or automotive-qualified versions available in the same family.

Replacement Considerations

Direct substitutes include ULN2001D1013TR and ULQ2001DR. Verify pinout compatibility and thermal performance before substitution.
