Overview
The DDTC114EE-7 is an NPN pre-biased transistor manufactured by Diodes Incorporated in a SOT523 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 10kΩ and R2 = 10kΩ. The device supports a maximum supply voltage (VCC) of 50V and a continuous collector current (IO) of 50mA. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at 5mA, a transition frequency (fT) of 250MHz, and a power dissipation rating of 150mW. Operating temperature ranges from -55°C to +150°C.
Feature Summary

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 lead-free status directly with the manufacturer or authorized distributors before procurement.
Selection Notes
Select this component when a compact NPN digital transistor with equal internal biasing resistors is required. Ensure the 50mA output current and 50V voltage ratings align with the target application's load requirements. Verify thermal management needs given the 150mW power dissipation limit in the SOT523 package.
Part Context
This part belongs to the DDTC (R1 = R2 Series) EE family from Diodes Incorporated. It serves as an NPN counterpart to complementary PNP types within the same series. The 'EE' designation indicates the specific resistor ratio configuration and package type used across this product line.
Replacement Considerations
Check for direct equivalents within the DDTC114EE series or other manufacturers offering SOT523 NPN pre-biased transistors with identical 10kΩ/10kΩ resistor ratios. Verify pinout compatibility and electrical parameter matching before substitution.
FAQ
What are the nominal values of the built-in biasing resistors?
For the DDTC114EE, both the base resistor (R1) and emitter resistor (R2) have nominal values of 10kΩ.
Is this component suitable for automotive applications?
While standard versions may not be explicitly qualified, Diodes offers automotive-grade parts qualified to AEC-Q101/100/200 standards. Contact the manufacturer for specific automotive qualification details.
What is the maximum power dissipation?
The maximum power dissipation is 150mW at an ambient temperature of +25°C, requiring derating at higher temperatures.
