XD62002 – Darlington Transistor Array Driver – Xinluda

The Xinluda XD62002 is a 7-channel high-voltage, high-current NPN Darlington transistor array (sink driver) rated 500 mA per channel at up to 50 V, with integrated output clamp diodes and a 10.5 kohm + Zener input stage for 14-25 V PMOS logic.

The Xinluda XD62002 is a 7-channel high-voltage, high-current Darlington transistor array configured as an open-collector NPN sink driver. It is a function- and pin-compatible member of the industry-standard TD62002/ULN200x-class Darlington array family, offering seven independent Darlington pairs with common emitters in a compact package. The XD62002 (Xinluda XD2002-series) variant features a 10.5 kohm series resistor with an integrated Zener diode on each input, making it suited to driving from 14-25 V PMOS logic levels.

Each channel is capable of sinking up to 500 mA at output voltages up to 50 V, and every output includes a built-in clamp (free-wheeling) diode to safely switch inductive loads such as relays, solenoids, and stepper-motor windings without an external protection diode.
