Overview
The DDTC114WE-7-F is an NPN pre-biased transistor from the DDC (R1≠R2 Series) E manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 22 kΩ. The device is housed in a surface-mount SOT523 package. Key electrical ratings include a supply voltage (VCC) of 50 V, a maximum output current (IOUT) of 100 mA, and a power dissipation (PD) of 150 mW. The transition frequency (fT) is typically 250 MHz at VCE = 10V and IE = 5mA.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated unequal biasing resistors (R1≠R2) to simplify circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- General-purpose switching applications
- Driver circuits for small signal loads
- Logic interface and level shifting
Procurement Notes
Verify the complete part number against official documentation, as ordering suffixes such as -7-F indicate specific packaging configurations like reel size and tape width. Confirm that the component meets required environmental standards, including RoHS 3 compliance and halogen-free specifications, before finalizing procurement orders.
Selection Notes
Select this component when an NPN pre-biased transistor with distinct base and emitter resistor values is required. Ensure the application operates within the specified 50 V supply voltage limit and 100 mA output current constraints. Verify that the SOT523 package dimensions align with the target PCB layout and thermal management requirements.
Part Context
This component belongs to the DDC (R1≠R2 Series) E family of NPN pre-biased transistors. Complementary PNP types are available under the DDTA series designation. The product line utilizes epitaxial planar die construction and is designed for surface-mount assembly in compact electronic systems.
Replacement Considerations
Direct substitutes within the same series include DDTC114YE-7-F and DDTC124XE-7-F, provided their specific R1 and R2 resistance values match the circuit requirements. Verify package compatibility and electrical ratings before substitution.
