7 NPN Darlington Transistor Pairs: Each ULN2003A series device contains seven independent NPN Darlington pairs, allowing for multiple channels of control.High Voltage Output: These devices are rated for high-voltage outputs, typically up to 50V.High Current Capability: Each Darlington pair can handle a collector current of 500mA. The pairs can be paralleled for higher current demands.Integrated Clamp Diodes: Includes common-cathode clamp diodes for switching inductive loads, such as relays or solenoids. These are also known as flyback diodes.Logic Compatibility: Designed with 2.7k? series base resistors for direct interfacing with TTL or 5V CMOS devices. Other versions exist (ULN2002A for 14V to 25V PMOS, ULN2004A for 6V to 15V CMOS/PMOS).Package: Available in the easy-to-use 16-pin SOP (Small Outline Package), also referred to as SOIC-16. The "SMD" part of the query indicates it's a surface-mount device.Thermal Shutdown Protection: Includes thermal shutdown protection to prevent damage from overheating.
