DTC114YUBTL

Overview

The DTC114YUBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device incorporates a base resistor (R1) of 10kΩ and an emitter-base resistor (R2) of 47kΩ. Packaged in the compact UMT3F (SOT-323FL) surface-mount format, it offers a power dissipation rating of 200mW and a DC current gain (hFE) of at least 68. The component supports a maximum operating temperature of 150°C and complies with RoHS standards.

Feature Summary

• Integrates internal biasing resistors to eliminate the need for external input components in inverter configurations.
• Provides high-density surface-mount packaging suitable for space-constrained electronic designs.
• Ensures stable switching performance through standardized NPN bipolar junction transistor characteristics.

Applications

• General-purpose logic level inversion circuits
• Driver stages for low-current loads such as LEDs or relays
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compliance with automotive restrictions if applicable, as standard grades may not be qualified for vehicle use. Confirm lead times and minimum order quantities directly with authorized distributors prior to ordering.

Selection Notes

Select this component when a compact NPN switch with integrated biasing is required. Compare R1 and R2 values against other DTC114 variants to match specific drive requirements. Consider the UMT3F package dimensions for PCB layout constraints and verify thermal dissipation capabilities within the target enclosure environment.

Part Context

This part belongs to the ROHM DTC114 series of digital transistors, which are designed to replace multiple discrete components. The series includes various resistor combinations and packages. The YUB variant specifically denotes the UMT3F package with defined resistance ratios, distinguishing it from other series members like the TE or EE variants.

Replacement Considerations

Direct substitutes include DTC114YUAT106 and DTC114YU3T106 from ROHM, which share similar electrical characteristics and package types. Cross-brand equivalents should be evaluated based on matching VCEO, IC, and resistor values to ensure functional compatibility without redesigning the surrounding circuitry.
