Show Product Description

Experience powerful and reliable performance with the ULN2003 High Voltage and High Current Transistor, featuring a robust 16-pin design and excellent heat resistance. Manufactured by ULN, model ULN2003, this transistor is an ideal solution for interfacing digital systems with high-power components, enabling seamless signal processing and efficient handling of heavy loads. The ULN2003 is engineered with each internal Darlington pair connected to a 2.7K ohm base resistor in series, allowing direct integration with TTL and CMOS circuits at a standard operating voltage of 5V. This unique feature eliminates the need for additional logic buffers or processing circuits, streamlining your design process and making the ULN2003 a top choice for electronics engineers and developers. Boasting a high working current of up to 500mA per channel and capable of withstanding voltages up to 50V when off, the ULN2003 excels in applications that require control of large loads, such as motors, relays, lamps, and automation systems. For projects that demand even greater load current, its outputs can be paralleled to deliver superior performance. Encased in a high-quality plastic package—available in DIP-16 or SOP-16 configuration—the ULN2003 is easy to mount on printed circuit boards and offers enhanced protection against thermal and mechanical stress. Produced with advanced manufacturing techniques, it guarantees stable and long-lasting operation, making it suitable for industrial environments, laboratories, home automation systems, and hobby electronics projects. Key benefits of the ULN2003 include circuit simplification, reduced component count, and improved system reliability. Its high thermal resistance ensures dependable operation under demanding conditions, reducing the risk of heat-related failures. For optimal use, install the ULN2003 in a dry location, avoid exposure to moisture or chemicals, and ensure correct pin connections according to the technical datasheet. Choose the ULN2003 High Voltage and High Current Transistor as the core component for your electronic projects and enjoy exceptional performance and reliability in controlling heavy loads, regardless of your workspace or application.
