Overview
The DDTC144EE-7 is an NPN pre-biased transistor manufactured by Diodes Incorporated in a SOT523 surface-mount package. It features built-in biasing resistors with R1 and R2 both nominally set to 47 kΩ. The device supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA, with a maximum power dissipation of 150 mW. It exhibits a transition frequency of 250 MHz and operates within a temperature range of -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
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size and quantity per reel. Confirm compliance requirements including RoHS and halogen-free status directly with the manufacturer or authorized distributors before procurement.
Selection Notes
Select this component when an NPN digital transistor with equal base and emitter biasing resistors is required. Ensure the application voltage does not exceed 50 V and the current demand remains within the 100 mA limit. Verify thermal management capabilities given the 150 mW power dissipation rating in the SOT523 package.
Part Context
This part belongs to the DDTC (R1 = R2 Series) EE family from Diodes Incorporated. Complementary PNP types are available within the same series, designated as DDTA. The product line focuses on providing integrated biasing solutions for small signal switching applications.
Replacement Considerations
Complementary PNP versions within the same series are available. Verify pinout compatibility and electrical characteristics when considering alternative manufacturers or different resistor values within the same package type.
