Overview
The DDTC144VE-7 is an NPN pre-biased small signal transistor manufactured by Diodes Incorporated in a SOT523 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 47 kΩ and R2 = 10 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a DC current gain (GI) of 33 at IO = 5 mA, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated biasing resistors (R1≠R2) simplify circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony-free "Green" device
Applications
- Inverter circuits
- Switching applications
- Driver circuits
Procurement Notes
Verify the complete part number against official documentation, as suffixes like '-7-F' define specific packaging configurations such as reel size and tape width. Confirm that the component meets required environmental standards, including RoHS and halogen-free specifications, before finalizing procurement orders.
Selection Notes
Select this component when an NPN digital transistor with unequal internal biasing resistors (47kΩ/10kΩ) is required. Ensure the application operates within the 50V supply limit and 100mA output current constraints. Verify thermal management requirements against the 150mW power dissipation rating.
Part Context
This component belongs to the DDTC (R1≠R2 SERIES) E family of NPN pre-biased transistors. It serves as the complementary counterpart to the DDTA series PNP types. The 'E' suffix indicates the SOT523 package format, distinguishing it from other package variants within the broader DDTC product line.
Replacement Considerations
Complementary PNP types are available in the DDTA series. Direct replacements must match the SOT523 package, 47kΩ/10kΩ resistor ratio, and 50V/100mA electrical ratings.
FAQ
What are the nominal values of the built-in biasing resistors?
For the DDTC144VE model, the nominal resistance values are R1 = 47 kΩ and R2 = 10 kΩ.
What is the maximum supply voltage rating?
The absolute maximum supply voltage (VCC) rating for this device is 50 V.
Is this component suitable for automotive applications?
Standard versions are not explicitly qualified for automotive use. For applications requiring AEC-Q100 qualification or IATF 16949 manufacturing, contact Diodes Incorporated directly.
