Overview
The DDTD123EC-7-F is an NPN pre-biased surface-mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrates built-in biasing resistors within a single SOT-23 package. The device supports a maximum supply voltage of 50V and a continuous collector current of 500mA, with a power dissipation rating of 250mW at 25°C ambient temperature. Nominal internal resistor values are R1 = 2.2kΩ and R2 = 2.2kΩ. It operates across a temperature range of -55°C to +150°C and complies with RoHS standards.
Feature Summary
- Integrates dual biasing resistors (R1 and R2) to simplify circuit design and reduce component count.
- Utilizes epitaxial planar die construction for reliable surface-mount performance.
- Manufactured using halogen-free and antimony-free green molding compounds.
Applications
- General-purpose switching applications requiring integrated base drive.
- Driver circuits for low-power loads in consumer electronics.
- Logic interface buffering between microcontrollers and peripheral devices.
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details and availability status. Confirm that the requested quantity aligns with standard reel sizes. Ensure compliance with relevant environmental directives such as RoHS before finalizing procurement orders.
Selection Notes
Select this component when a single NPN transistor with fixed internal biasing resistors is required. Verify that the nominal resistance values of 2.2kΩ for both R1 and R2 match the intended input drive characteristics. Ensure the application voltage does not exceed the 50V absolute maximum rating.
Part Context
This part belongs to the DDTD series of NPN pre-biased transistors from Diodes Incorporated. It is distinct from complementary PNP types (DDTB series) and other variants within the family that feature different resistor ratios or obsolete configurations. The 'EC' designation specifically identifies the 2.2kΩ/2.2kΩ resistor combination.
Replacement Considerations
Direct functional substitutes include other DDTD series parts with identical 2.2kΩ/2.2kΩ resistor values, such as DDTD123YC-7-F. Verify pinout compatibility and thermal characteristics before substitution.
