UDN2004A High-Current Darlington Transistor Array (DIP-16)

The UDN2004A is a high-performance Darlington transistor array designed for high-current and high-voltage applications. It features seven independent NPN Darlington pairs, each equipped with an internal suppression diode, making it perfectly suited for driving inductive loads such as relays, solenoids, DC motors, and stepping motors. The device is specifically engineered to interface between standard low-level logic (6V to 15V CMOS) and power peripherals, providing a reliable bridge for electronic control systems. With its robust output current capability and integrated protection features, the UDN2004A simplifies circuit design by reducing the need for external components while ensuring long-term hardware reliability in industrial and automotive environments.

Key Features:

Capable of handling up to 500mA per channel for robust load control.

Designed with high-voltage breakdown ratings reaching 50V for safety.

Includes internal clamp diodes to protect against inductive load transients.

Optimized for low-voltage logic interfaces including 6V to 15V CMOS and PMOS.

Standard 16-pin dual in-line package (DIP) for through-hole mounting.
