ULN2803A, Darlington Transistor Array IC, SMD SOP-18 Package Type

The ULN2803A is an 8-channel Darlington transistor array designed for interfacing logic level circuits (like TTL and CMOS) with high-current/high-voltage loads. In the SOP-18 surface mount package, it is a compact and efficient solution for driving relays, solenoids, stepper motors, LEDs, and other loads requiring higher current than a standard logic output can handle.

Key Features:

• 8-channel Darlington transistor array
• TTL and CMOS logic compatible inputs
• 500 mA output current per channel
• Built-in clamp diodes for inductive load protection
• High-voltage outputs up to 50V
• Ideal for driving relays, lamps, or stepper motors

Additional Specifications:

• Package Type: SOP-18
• IC type: Darlington Transistor Array
• Mounting Style: SMD
