XD2004 – Darlington Transistor Array – Xinluda

The Xinluda XD2004 is a seven-channel high-voltage, high-current Darlington transistor array (ULN2004-type) with integrated output clamp diodes and a 10.5 kΩ series base resistor for direct interfacing to CMOS and PMOS logic. Available for RFQ from Pacific Component Xchange.

The XD2004 from Xinluda is a monolithic high-voltage, high-current Darlington transistor array containing seven NPN Darlington pairs. It is a member of the industry-standard ULN200x family and is functionally comparable to the ULN2004A. Each of the seven outputs is rated for up to 500 mA of collector current and includes a common-cathode clamp diode, making the device ideal for driving inductive loads such as relays, solenoids, stepper motors, and lamps.

The XD2004 variant integrates a 10.5 kΩ series base resistor on each input, allowing the device to be driven directly from CMOS and PMOS logic. The CMOS supply range is 6 V to 15 V, and the device is also specified for use with 14 V to 25 V PMOS devices. High-voltage outputs rated to 50 V and an extended -40°C to +85°C operating range make it well suited to industrial control and interface applications.
