DTC114YCAT116

Overview

The DTC114YCAT116 is a single NPN digital transistor from Rohm Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes an internal base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms. Key electrical characteristics include a DC current gain (hFE) of at least 68 at 5 mA and 5 V, a saturation voltage of 300 mV maximum at 250 µA base current and 5 mA collector current, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW in the SST3 package.

Feature Summary

• Integrates NPN bipolar junction transistor with dual bias resistors for simplified switching applications
• Provides high-speed performance with a 250 MHz transition frequency suitable for digital logic interfaces
• Features low saturation voltage to minimize power loss during conduction states

Applications

• General-purpose digital switching circuits
• Interface between microcontrollers and peripheral devices
• Inverter circuits requiring minimal external components

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches SST3 or SOT-23-3 requirements. Ensure RoHS compliance aligns with project environmental standards. Validate batch codes for traceability purposes before integration into production lines.

Selection Notes

Select this component when a compact NPN switch with integrated biasing is required. Compare R1 and R2 values against load requirements to ensure adequate drive capability. Consider the 200 mW power dissipation limit relative to ambient temperature conditions. Verify that the 50 V breakdown voltage exceeds peak circuit voltages.

Part Context

This part belongs to the DTx series of digital transistors from Rohm Semiconductor. These devices combine a single transistor with pre-biased resistors to reduce board space and assembly complexity. The DTC114YCA variant specifically denotes NPN polarity with 10 kOhm base resistance and 47 kOhm emitter resistance ratios.

Replacement Considerations

DTC114YKAT146 by Rohm Semiconductor is listed as a parameter-equivalent substitute. DDTC114YCA-7-F by Diodes Incorporated is also identified as a potential replacement option.
