The Xinluda XD2003 is a high-voltage, high-current 7-channel Darlington transistor array functionally aligned with the industry-standard ULN2003 family. Each of its seven open-collector NPN Darlington pairs is rated for up to 500 mA of collector current and a 50 V output, making the device a workhorse interface for driving inductive and high-current loads directly from low-power logic. An integrated common-cathode clamp (free-wheeling) diode network provides built-in protection when switching relays, solenoids, and other inductive loads, while the inputs are compatible with 5 V TTL and CMOS logic levels.
The XD2003 is a Xinluda-branded part with limited authorized-distributor coverage, which can make it difficult to procure through mainstream channels. Pacific Component Xchange specializes in sourcing hard-to-find and obsolete power-management ICs and driver components like the XD2003. We help engineers and buyers secure authentic, trusted and guaranteed inventory with global shipping and responsive support. Whether you need a small quantity for a prototype run or volume quantities for production, our team can locate the XD2003 and verify authenticity before it ships. Request a quote (RFQ) today and our sourcing specialists will respond with availability and pricing.
The XD2003 is a 7-channel high-voltage, high-current Darlington transistor array from Xinluda. It is functionally in the ULN2003 class, providing seven open-collector Darlington outputs rated at 500 mA and 50 V for driving relays, solenoids, motors, and displays.
The XD2003 belongs to the same ULN2003-class family of 7-channel Darlington sink drivers, sharing the core architecture of seven 500 mA / 50 V open-collector channels with an integrated common-cathode clamp diode and TTL/CMOS-compatible inputs. Always confirm pinout and electrical parameters against the datasheet for your specific design before substituting.
The XD2003 is supplied in a DIP-16 package. Confirm the required package code when submitting your RFQ, and note that Xinluda offers an SOP-16 surface-mount version under a separate part number (XL2003).
With 500 mA per channel, 50 V outputs, and an integrated common-cathode clamp diode, the XD2003 is well suited to inductive and high-current loads such as relays, solenoids, stepper/DC motors, LED and gas-discharge displays, and thermal printheads.
Yes. Like other ULN2003-class arrays, multiple XD2003 outputs can be connected in parallel to increase the total current-handling capability beyond the 500 mA per-channel rating.
The XD2003 is a Xinluda-branded part with limited authorized-distributor availability, so pricing is provided on a quote basis. Pacific Component Xchange sources this hard-to-find component, verifies authenticity, and ships globally. Submit an RFQ for current availability and pricing.
