ULN2002D1013TR

Overview

The ULN2002D1013TR is a high-voltage, high-current Darlington array manufactured by STMicroelectronics. It contains seven open-collector Darlington pairs with common emitters within a single package. Each channel supports a continuous collector current of 500 mA and withstands peak currents up to 600 mA. The device features an output voltage rating of 50 V and includes integrated suppression diodes for inductive load driving. Inputs are pinned opposite outputs to simplify board layout. It operates within a temperature range of -20 °C to 85 °C and is housed in a 16-pin SOIC surface-mount package.

Feature Summary

• Seven Darlington pairs per package with integrated suppression diodes for inductive loads
• Inputs pinned opposite outputs 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 printheads
• High-power buffering applications

Procurement Notes

Verify the specific suffix D1013TR against official STMicroelectronics documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure compatibility with industrial operating temperatures ranging from -20 °C to 85 °C. Confirm that the NPN polarity and 50 V output voltage meet the target circuit requirements before finalizing procurement.

Selection Notes

Select this component when interfacing with PMOS logic families requiring input voltages between 14 V and 25 V, as distinguished from other ULN variants. Choose the SOIC-16 package for surface-mount assembly constraints. Verify that the 500 mA per-channel current rating suffices for the intended load, noting that outputs can be paralleled for higher current demands if necessary.

Part Context

This part belongs to the ULN200x series of high-voltage Darlington arrays from STMicroelectronics. It shares architectural similarities with the ULN2001, ULN2003, and ULN2004, differing primarily in input threshold characteristics tailored for specific logic families. The D1013TR designation indicates the surface-mount SOIC-16 variant supplied in tape-and-reel format for automated assembly processes.

Replacement Considerations

Direct functional substitutes include the ULN2003D1013TR for TTL/CMOS interfaces or the ULN2004D1013TR for broader CMOS/PMOS compatibility. Verify pin-to-pin compatibility and ensure the replacement variant matches the required input voltage thresholds for the specific logic family in use.
