XL62003 – Darlington Transistor Array – Xinluda

The Xinluda XL62003 is a 7-channel NPN Darlington transistor array in an SOP-16 package, with outputs rated to 50V and 500mA per channel and integrated common-cathode clamp diodes for driving inductive loads.

The XL62003 from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.) is a high-voltage, high-current Darlington transistor array consisting of seven NPN Darlington pairs. Each channel integrates a common-cathode clamp diode, making the device well suited for switching inductive loads such as relays, solenoids, and stepper-motor windings. Functionally, the XL62003 belongs to the widely used ULN2003-type driver family and is offered in a compact SOP-16 surface-mount package.

Designed for general-purpose interface and driver applications, the XL62003 accepts logic-level inputs and provides current-sinking outputs capable of handling load currents that standard logic gates and microcontroller pins cannot drive directly. A series base resistor on each input allows the device to be driven directly from TTL or 5 V CMOS logic.
