ULN2803CDWR Darlington Transistor

Description

The ULN2803C is a high-voltage, 500-mA Darlington transistor array with eight NPN Darlington pairs, featuring common-cathode clamp diodes for inductive load switching. It’s suitable for various applications, including factory automation, building automation, appliances, IP network cameras, HVAC valve control, relay drivers, solenoid drivers, lamp drivers, and stepper motor control. Each Darlington pair has a 500 mA collector current rating and can be connected in parallel for higher current capacity. The device includes a 2.7-kΩ series base resistor for each Darlington pair, making it compatible with TTL or 5-V CMOS devices.
