DTC124EUBHZGTL

Overview

The DTC124EUBHZGTL is an NPN digital transistor from ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector current of 0.1 A and a supply voltage of 50 V. The device integrates two resistors: R1 at 22 kΩ and R2 at 22 kΩ, maintaining a ratio of 1. Packaged in the UMT3F (SOT-323) surface-mount format, it supports a maximum power dissipation of 200 mW. The component is RoHS compliant and supplied in tape-and-reel packaging with a unit quantity of 3000.

Feature Summary

• Integrates internal biasing resistors to eliminate external input resistor requirements for inverter circuits.
• Provides simplified on/off control logic by requiring only signal setting without complex bias networks.
• Utilizes compact SMD packaging suitable for space-constrained surface mount applications.

Applications

• Inverter circuits utilizing built-in biasing for simplified topology.
• General-purpose switching applications requiring integrated base drive.
• Digital logic interface circuits where external bias components are minimized.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure package and reel specifications match the design requirement. Confirm that the component status aligns with project lifecycle needs, as availability may vary. Ensure compliance with RoHS directives and check for any automotive qualification requirements if the application demands higher reliability standards beyond standard industrial grades.

Selection Notes

Select this component when an NPN digital transistor with equal internal resistors (R1=R2=22kΩ) is required. It is suitable for designs needing a single pre-biased transistor in a small footprint. Consider complementary PNP types like the DTA124E series if push-pull configurations are necessary. Verify that the 50V collector-emitter voltage and 100mA current ratings meet the load requirements.

Part Context

This part belongs to the ROHM DTC124 series of digital transistors, which are designed to replace discrete resistor-transistor combinations. The 'EUBH' suffix typically denotes specific packaging and environmental compliance attributes within the product line. These devices are engineered to reduce board space and assembly costs by integrating the bias network directly into the semiconductor package.

Replacement Considerations

The DTC124EU3HZGT106 is listed as a similar specification alternative within the same family. Verify pin compatibility and exact resistance values before substitution. Other NPN digital transistors with similar R1/R2 ratios may serve as functional equivalents if electrical parameters align with the original design constraints.
