The XL2003 from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd) is a high-voltage, high-current 7-channel Darlington transistor array belonging to the popular ULN2003-type driver family. Each of its seven NPN Darlington pairs delivers an open-collector output rated up to 500 mA with a sustaining voltage of 50 V, making the device a versatile interface between low-power TTL/5 V CMOS logic and higher-current inductive and resistive loads. An integrated common-cathode output clamp (suppression) diode simplifies driving solenoids, relays, and motors, while on-chip 2.7 kΩ input series resistors and Zener-protected inputs allow direct connection to common logic families. The XL2003 is supplied in a compact SOP-16 surface-mount package.
The Xinluda XL2003 has little to no authorized-distributor availability outside of a handful of Asian catalog sources, which can stall production for designs that depend on this specific ULN2003-type driver. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, drivers, and optocouplers. We help engineers and buyers secure scarce parts like the XL2003 with rigorous authenticity verification, traceability, and global shipping. Whether you need a single reel for a prototype run or volume quantities for production, our team sources to your requirements. Request a quote (RFQ) today for current XL2003 availability, lead time, and pricing, and let Pacific Component Xchange keep your build on schedule.
The XL2003 is a high-voltage, high-current 7-channel Darlington transistor array from Xinluda. It is a ULN2003-type driver with open-collector outputs rated 500 mA per channel and 50 V, supplied in a SOP-16 package.
The XL2003 belongs to the same ULN2003-type 7-channel Darlington driver family and shares the typical 500 mA / 50 V ratings, 2.7 ku03a9 input resistors, and integrated clamp diode. Always confirm pinout and exact electrical limits against the XL2003 datasheet before substituting in a specific design.
The XL2003 is offered in a SOP-16 surface-mount package, typically supplied on tape and reel.
With 500 mA per channel and an integrated suppression diode, the XL2003 is suited to driving relays, solenoids, DC and stepper motors, LED and gas-discharge displays, filament lamps, and thermal print heads. Channels can be paralleled for higher current.
Yes. The Xinluda XL2003 has limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find parts like this and can provide current stock and lead-time information on request.
