ULN2004D1013TR

Product Overview

STMicroelectronics ULN2004D1013TR is a surface-mount bipolar transistor array with seven NPN Darlington channels in a 16-SOIC package. It is rated for 500mA collector current and 50V collector-emitter breakdown voltage, with VCE saturation specified as 1.6V at 500µA base current and 350mA collector current. The operating temperature range is -40°C to 85°C (TA).

Key Features

• Seven NPN Darlington transistor channels in a single 16-SO surface-mount array.
• Maximum collector current rating of 500mA.
• Collector-emitter breakdown voltage rating of 50V.
• VCE saturation voltage of 1.6V at 500µA base current and 350mA collector current.
• Collector cutoff current maximum of 50µA.
• Operating temperature range of -40°C to 85°C (TA).
• 16-SOIC package with 3.90mm body width.

Applications

• Switching relay coils in control and power-interface circuits.
• Driving indicator or load devices such as lamps, buzzers, or solenoids.
• Buffering control signals to transistor-switched loads.

Design & Procurement Notes

The 500mA collector current and 50V collector-emitter breakdown ratings define the switching envelope for relay coils or other loads, so load voltage and current should remain within these limits. The 1.6V VCE saturation value at 500µA base drive and 350mA collector current should be considered when estimating switch voltage drop and power dissipation. The 50µA collector cutoff current may matter in leakage-sensitive off-state circuits. Board layout, thermal management, and external connections should account for the 16-SOIC package and -40°C to 85°C ambient range.
