ULN2003A
Manufacturer: STMicroelectronics
The ULN2003A is a high voltage, high current Darlington transistor array consisting of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The package is a 16-pin DIP (dual inline package) or SOIC (small outline integrated circuit) package. The device is commonly used to drive stepper motors, relays, and other high-current or high-voltage loads.
Product parameters:
Maximum collector-emitter voltage: 50 V
Maximum collector current: 500 mA per channel, 1.5 A total for all channels
Maximum power dissipation: 2.25 W
Input voltage: 5-15 V
High-voltage outputs: 50 V
Common-cathode clamp diodes for inductive load transient suppression
Product introduction:
The ULN2003A is a popular and versatile integrated circuit that provides seven Darlington transistor pairs in a single package. This allows for efficient driving of high-current loads such as motors, relays, solenoids, and other inductive loads. The common-cathode clamp diodes are included in the package to protect the device from inductive load transients. The ULN2003A is commonly used in industrial automation, robotics, and other high-power applications. It is a cost-effective solution for driving high-current loads without the need for additional components.
