Key Features
- 7-channel NPN Darlington array with 500 mA per-channel sink current and 50 V output voltage, driving relays, solenoids, and stepper motors directly from logic
- Integrated transient-suppression clamp diodes on each output eliminate external freewheeling diodes and reduce component count
- 16-pin SOIC package in tape-and-reel (TR) format optimizes automated SMT assembly for high-volume production
- Open-collector outputs allow direct wiring to different voltage rails up to 50 V, decoupling load voltage from logic supply
Applications
The ULQ2004D1013TR is used in industrial PLC output stages and motor-drive interfaces where 7 independent relay or solenoid coils must be controlled simultaneously from 3.3 V or 5 V logic lines. Its 500 mA per-channel sink capability and integrated 50 V clamp diodes make it ideal for driving stepper motor windings, lamp arrays, and LED displays in building automation and consumer appliances. The SOIC-16 tape-and-reel packaging suits high-volume PCB assembly lines in HVAC controllers and smart home devices.

Frequently Asked Questions
How many output channels does the ULQ2004D1013TR provide, and what is the maximum sink current per channel?
The ULQ2004D1013TR contains 7 independent NPN Darlington output channels, each rated for a continuous collector sink current of 500 mA and a peak of up to 600 mA. The 50 V output voltage rating allows direct drive of 12 V, 24 V, or 48 V relay coils, solenoids, and lamp loads without additional level-shifting circuitry.
Can the ULQ2004D1013TR replace a ULN2004A in an existing PCB layout without hardware changes?
Yes, the ULQ2004D1013TR is functionally and pin-compatible with the ULN2004A in a 16-pin SOIC footprint, offering identical 500 mA / 50 V ratings and the same internal Darlington pair with suppression diode topology. The main difference is STMicroelectronics' tape-and-reel (TR) suffix for reel packaging, making it a direct drop-in replacement for SMT assembly lines.
What input voltage range triggers the ULQ2004D1013TR outputs, and does it accept 3.3 V logic?
The ULQ2004D1013TR is optimized for 5 V CMOS and TTL logic inputs; input high threshold is approximately 2.4 V, so 3.3 V logic signals reliably turn on the Darlington pairs. At 5 V input the typical input current is under 1 mA per channel, imposing minimal loading on microcontroller GPIO pins driving the array.
Why are the integrated clamp diodes in the ULQ2004D1013TR important for relay and solenoid drive circuits?
Inductive loads such as relay coils and solenoids generate voltage spikes exceeding 50 V when switched off. The ULQ2004D1013TR includes a suppression clamp diode on each of its 7 output channels, rated to absorb these transients and clamp the collector voltage, protecting both the Darlington transistor and upstream logic from damage without requiring 7 external flyback diodes.
