Overview
The DDTD123TC-7-F is an NPN pre-biased surface-mount transistor manufactured by Diodes Incorporated. It features a built-in biasing resistor network consisting of R1 (2.2 kΩ) and an open circuit for R2, housed in an SOT-23 package. The device supports a maximum supply voltage of 50 V and a continuous collector current of 500 mA. Thermal characteristics include a power dissipation rating of 250 mW and a junction-to-ambient thermal resistance of 500 °C/W. Operating and storage temperatures range from -55 °C to +150 °C.
Feature Summary
- Integrates internal biasing resistors to simplify circuit design and reduce component count.
- Utilizes epitaxial planar die construction for reliable semiconductor performance.
- Compliant with RoHS standards and free from halogen and antimony.
Applications
- General-purpose switching applications requiring integrated base drive.
- Driver circuits for low-power loads where space efficiency is critical.
- Automotive electronics utilizing AEC-Q100 qualified variants.
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm availability status and packaging details. Confirm that the selected variant meets all required environmental compliance standards for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a single NPN transistor with a 2.2 kΩ base resistor is required. Ensure the application current does not exceed the 500 mA limit and verify that the SOT-23 package dimensions fit the target PCB layout constraints.
Part Context
