Applications

• Automotive applications requiring specific change control
• General-purpose switching circuits
• Driver circuits for logic interfaces

Procurement Notes

Verify the ordering suffix '-7-F' against the manufacturer's official documentation to confirm compliance with RoHS 3 standards and tape-and-reel packaging specifications. Confirm that the component status aligns with current production requirements, as datasheet records may indicate variations in availability or obsolescence for specific suffixes.

Selection Notes

Select this component when a compact dual complementary solution with integrated base resistors is required. Ensure the 47 kΩ resistor values match the target drive current and input voltage levels. Verify that the 30 mA output current capability meets the load requirements for both the NPN and PNP channels simultaneously.

Part Context

This part belongs to the DCX (XXXX) K series of dual complementary pre-biased transistors manufactured by Diodes Incorporated. The series offers various resistor combinations in the SOT26 package to accommodate different logic families and drive requirements.

Replacement Considerations

Check for other parts within the DCX series with matching 47 kΩ resistor values. Verify pinout compatibility and electrical characteristics such as breakdown voltage and current ratings before substituting.
