XL2003 – Darlington Transistor Array – Xinluda
The XL2003 from Xinluda is a 7-channel high-voltage, high-current Darlington transistor array (ULN2003-type) rated 500 mA per channel and 50 V, in a SOP-16 package. Available for RFQ at Pacific Component Xchange.
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.
Key Features
- 7 NPN Darlington pairs (open-collector outputs)
- Rated collector current: 500 mA per channel (channels can be paralleled for higher current)
- Output sustaining voltage: 50 V (VCEO)
- Integrated common-cathode output clamp / suppression diode for inductive-load driving
- 2.7 kΩ input series resistors for direct TTL / 5 V CMOS interfacing
- Package: SOP-16
Applications
- Relay and solenoid drivers
- DC motor and stepper motor drivers
- LED, filament-lamp and gas-discharge display drivers
- Thermal print-head drivers
- General-purpose logic-to-high-current load interfacing
Why Source XL2003 from Pacific Component Xchange
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.
