DTC043ZEBTL

Overview

The DTC043ZEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3F) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. The device features a typical base input resistance of 4.7 kΩ and an emitter-base resistance of 47 kΩ. DC current gain (hFE) is specified at a minimum of 80 when tested at 5 mA and 10 V. Power dissipation is rated at 150 mW, with a transition frequency of 250 MHz. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Integrates dual bias resistors (R1 and R2) internally to eliminate external components for basic switching applications.
• Designed as a pre-biased transistor to facilitate direct interfacing with logic gates or microcontroller I/O pins.
• Utilizes the compact SOT-416 footprint to support high-density surface mount assembly.

Applications

• Logic level shifting between different voltage domains.
• General-purpose switching circuits controlled by digital signals.
• Inverter configurations requiring minimal external component count.

Procurement Notes

Verify the specific suffix 'EBTL' against the manufacturer's official datasheet to confirm the exact resistor values and packaging configuration. Ensure that the sourcing channel provides documentation confirming RoHS compliance and Pb-free status. Cross-reference the part number with the latest production lifecycle status to confirm availability before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-current switching tasks. Compare the 4.7 kΩ base resistance against other variants if specific drive currents differ. Verify that the 50 V collector-emitter rating exceeds the maximum load voltage in the target application to ensure reliable operation under all conditions.

Part Context

This component belongs to the DTC043 series of digital transistors produced by ROHM Semiconductor. These devices are standard-grade products designed for general electronic equipment. They are distinct from automotive-grade parts and are not recommended for use in automotive applications. The series focuses on providing cost-effective, space-saving solutions for consumer electronics and industrial control systems.

Replacement Considerations

The DTC143ZETL is a documented substitute within the same family, offering identical 50 V and 100 mA ratings but featuring a different internal resistor ratio. Verify pinout compatibility and thermal performance before substitution.
