DTC023EEBTL

Overview

The DTC023EEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates within a supply voltage of 50 V and supports a continuous collector current of 100 mA. The device incorporates an input resistance (R1) of 2.2 kΩ and an emitter-base resistance (R2) of 2.2 kΩ, with a typical resistor ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 20 at 5 mA and 10 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 150 mW. The component is housed in a compact SOT-416FL (EMT3F) surface-mount package, suitable for high-density applications.

Feature Summary

• Integrates NPN transistor with dual internal bias resistors to reduce external component count and PCB space.
• Provides stable switching performance with a defined resistor ratio and consistent current gain specifications.
• Designed for surface-mount assembly in small-footprint packages compatible with automated manufacturing processes.

Applications

• General-purpose switching circuits in consumer electronics
• Driver stages for low-current loads in portable devices
• Logic level translation and interface buffering

Procurement Notes

Verify the specific suffix 'EBTL' against the official ROHM datasheet to confirm the exact resistor values and packaging configuration. Ensure that the procurement source provides authentic components with traceable documentation, as counterfeit parts may exhibit incorrect electrical parameters or packaging discrepancies.

Selection Notes

Select this component when a single NPN switch with integrated biasing is required in a compact form factor. The 2.2 kΩ input resistance suits applications driven by standard logic outputs. Consider the 150 mW power dissipation limit and 50 V voltage rating during thermal and electrical stress analysis.

Part Context

This part belongs to the DTC023 series of digital transistors from ROHM Semiconductor. The series offers various resistor combinations and packages to accommodate different drive requirements. The EMT3F package variant provides a balance between size and thermal performance for general-purpose applications.

Replacement Considerations

The DTC123EUB is listed as a similar specification replacement with identical 2.2 kΩ resistors but housed in a SOT-323FL package. Verify pinout compatibility and package dimensions before substitution.
