DTC014EUBTL

Overview

The DTC014EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates within a collector-emitter voltage of 50 V and supports a continuous collector current of 50 mA. The device includes an internal base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 10 kOhms. Key electrical parameters include a minimum DC current gain (hFE) of 35 at 5 mA and 10 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. It is housed in the UMT3F (SOT-323FL) surface-mount package.

Feature Summary

• Integrates pre-biased resistors to eliminate external components for inverter configurations
• Provides high-speed switching capability with a 250 MHz transition frequency
• Offers compact surface-mount packaging for space-constrained designs

Applications

• General-purpose logic level shifting and signal inversion
• Driver circuits for small-signal loads and relays
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and specific tape-and-reel quantities against current production data sheets. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering processes.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-power switching applications. Compare internal resistance values against target input impedance requirements. Verify that the 50 V collector-emitter rating exceeds the maximum operating voltage of the intended circuit environment.

Part Context

This part belongs to the DTC014 series of digital transistors from ROHM Semiconductor. It serves as the NPN counterpart to PNP variants such as the DTA014EUBTL. The series is designed for standard consumer electronics applications rather than automotive-grade environments, which require specialized qualification standards.

Replacement Considerations

Direct pin-compatible substitutes within the same family include DTC014YEBTL and DTC015EUBTL. Verify internal resistor ratios and hFE specifications before substitution to ensure circuit performance remains within acceptable limits.
