Overview
The DTC114YKA is an NPN digital transistor in a SOT-23-3L package, integrating bias resistors to simplify circuit design. It operates with a supply voltage up to 50V and input voltage up to 40V. Key electrical parameters include a typical DC current gain of 68, input resistance of 10 kΩ, and a resistance ratio (R2/R1) of 4.7. The device features a transition frequency of 250 MHz and supports an output current of up to 100 mA. Power dissipation is rated at 200 mW, with a junction temperature limit of 150°C.
Feature Summary
- Built-in thin-film bias resistors enable inverter circuit configuration without external input components
- Complete isolation of bias resistors allows negative input biasing and minimizes parasitic effects
- Simplified operation requiring only on/off condition settings for device design
Applications
- Inverter circuits
- Switching applications
- Logic interface circuits
Procurement Notes
Verify the specific ordering suffix 'KA' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets the required thermal and electrical ratings for the intended application environment before procurement.
Selection Notes
Select this component when a compact NPN digital transistor with integrated biasing is required. Consider the 10 kΩ input resistance and 4.7 R2/R1 ratio for appropriate base drive calculations. Verify that the 50V supply voltage rating and 100 mA output current capability align with system requirements.
Part Context
This part belongs to the DTC114 series of NPN digital transistors manufactured by Micro Commercial Components. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity. The SOT-23-3L package provides a small form factor suitable for portable electronics.
Replacement Considerations
Consult official substitution guides for equivalent NPN digital transistors with similar R1, R2, and hFE characteristics. Verify pinout compatibility and electrical ratings match the original design requirements before replacing.
