Ocral High Voltage,High Current Darlington Transistor Arrays

Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description
The eight NPN Darlington connected transistors in this family of arrays are ideally suited for interfacing between low logic level digital circuitry (such as TTL, CMOS or PMOS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of computer, industrial, and consumer applications. All devices feature open–collector outputs and free
wheeling clamp diodes for transient suppression The ULN2803 is designed to be compatible with standard TTL families while the ULN2804
is optimized for 6 to 15 volt high level CMOS or PMOS. 

Features

● VCE (Collector-Emitter Voltage): 30V - Suitable for moderate voltage applications.

● VCE(sat) (Saturation Voltage): 1.6V (max) - Low saturation voltage ensures efficient switching.

● ICEX (Collector Leakage Current): 50μA (max) - Minimizes power loss when transistors are off.

● Ii(ON) (Input Current - ON State): 1.1mA (typ) - Low input current requirement for effective switching.

● Ii(OFF) (Input Current - OFF State): 100μA (max) - Helps conserve power during standby.

● Package: SOP-18 - Compact surface-mount package for easy PCB integration.

Applications

● Relay Drivers: Effectively drives relay coils in industrial automation and control systems.

● Lamp Drivers: Controls high-power LEDs or incandescent lamps in signage and display applications.

● Stepper Motor Drivers: Provides reliable current amplification for stepper motor control circuits.

● Sensor Interfaces: Interfaces with sensors and actuators in automotive and industrial electronics.
