DTC014YUBTL

Overview

The DTC014YUBTL is an NPN digital transistor from ROHM Semiconductor, housed in a UMT3F (SOT-323FL) surface-mount package. It integrates bias resistors with R1 at 10 kΩ and R2 at 47 kΩ to simplify circuit design by eliminating external input components. Key electrical specifications include a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. The device features a transition frequency of 250 MHz and a minimum DC current gain of 68 at 5 mA and 5 V. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in bias resistors to configure inverter circuits without external input resistors
• Provides simplified operation by requiring only open/close condition settings
• Offers high-speed switching capability suitable for digital applications

Applications

• Inverter circuits
• Digital interface logic
• Signal switching applications

Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm pinout and resistor values, as variations exist within the family. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability through authorized distributors, as lead times may vary based on production schedules and regional demand.

Selection Notes

Select this component when an NPN digital transistor with a 50V rating and 100mA current capacity is required in a compact SOT-323FL package. The fixed 10kΩ/47kΩ resistor ratio is suitable for standard logic level interfacing. Consider thermal management if operating near the maximum power dissipation limit of 200mW in enclosed environments.

Part Context

This part belongs to the DTC014 series of pre-biased transistors designed for space-constrained digital circuits. The UMT3F package provides a small footprint compared to larger SOT packages, making it ideal for portable electronics and dense PCB layouts where board real estate is limited.

Replacement Considerations

Direct substitutes include other ROHM parts with identical resistor ratios and packaging, such as DTC014YEBTL, though package differences must be accounted for. Cross-manufacturer equivalents require matching NPN polarity, 50V VCEO, and similar hFE characteristics.
