Integrated biasing resistors with equal resistance values
RoHS compliant and halogen-free green device

Applications

Interface circuits
Driver applications
General-purpose switching

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size and tape width. Confirm compliance requirements including RoHS and halogen-free status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required. Ensure the 4.7 kΩ resistor value matches the circuit design needs. Verify that the SOT523 package dimensions and thermal characteristics fit the board layout constraints.

Part Context

This part belongs to the DDTC (R1 = R2) series of pre-biased transistors from Diodes Incorporated. Complementary PNP types are available within the DDTA series. The EE suffix indicates the SOT523 package configuration.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar electrical specifications and SOT523 packaging. Verify pinout compatibility and resistor values before substitution.

FAQ

What is the nominal value of the built-in biasing resistors?

The nominal resistance for both R1 and R2 is 4.7 kΩ.

Is this device suitable for automotive applications?

For automotive applications requiring AEC-Q100/101/200 qualification and PPAP capability, contact Diodes Incorporated directly as standard parts may not meet these specific requirements.
