Overview
The DDTC114TKA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and a built-in biasing resistor (R1) with a nominal value of 10 kOhms. The device is housed in an SC-59 package and supports a collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and power dissipation of 200 mW. It operates within a temperature range of -55°C to +150°C and includes a DC current transfer ratio (hFE) minimum of 100.
Feature Summary
- Integrates a single internal biasing resistor (R1 only) to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable performance.
- Available in a compact SC-59 surface mount case for space-constrained applications.
Applications
- General-purpose switching circuits
- Driver stages for logic interfaces
- Biasing networks for amplifier inputs
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging and compliance details. Ensure that the component meets all required environmental standards, such as RoHS compliance, before integration into final assemblies. Cross-reference datasheet revisions to confirm marking codes and electrical characteristics match the intended design specifications.
Selection Notes
Select this component when a single NPN pre-biased transistor with a 10 kOhm base resistor is required in an SC-59 package. Consider the thermal resistance and power dissipation limits relative to the expected operating ambient temperature. Verify that the 50 V breakdown voltage and 100 mA current ratings exceed the maximum circuit demands.
Part Context
This part belongs to the DDTC (R1-only series) KA family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor. Complementary PNP types are available within the same product family under the DDTA designation. The 'KA' suffix indicates the SC-59 package style used for this specific variant.
Replacement Considerations
Complementary PNP types are available within the same product family under the DDTA designation. Other variants in the DDTC114 series may offer different resistor values or package styles but maintain similar electrical characteristics.
