DTC015EEBTL

Overview

The DTC015EEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3F (SOT-416FL) surface-mount package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical base resistor of 10 kOhms and an emitter-base resistor of 10 kOhms, yielding a resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The maximum operating temperature reaches +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with dual internal bias resistors to simplify circuit design.
• Provides high-speed switching capability with a transition frequency of 250 MHz.
• Utilizes compact SMD packaging suitable for automated surface-mount assembly processes.

Applications

• General-purpose signal switching in consumer electronics.
• Driver circuits for low-power loads in industrial control systems.
• Logic level translation between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix 'EBTL' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the EMT3F package dimensions align with your PCB footprint requirements. Ensure supply chain sources provide authentic components from authorized distributors to avoid counterfeit risks associated with standard discrete semiconductors.

Selection Notes

Select this component when a single NPN switch with integrated biasing is required for space-constrained designs. The 10 kOhm input resistance offers a balanced drive current for standard logic outputs. Consider the 150 mW power dissipation limit during thermal analysis. Compare against other DTC01x series variants if different resistance ratios or voltage ratings are needed for specific application constraints.

Part Context

This part belongs to the ROHM DTC015EEB series of pre-biased transistors. It shares the same physical package and general topology as related models like DTC015EUBTL but differs in internal resistor values. The series is designed to replace multiple discrete components, reducing board space and assembly costs while maintaining consistent electrical performance across production batches.

Replacement Considerations

Direct substitutes include DTC015EEBTLDKR and DTC015EEBTLCT, which share identical electrical specifications and pin configurations. Verify that any alternative sourcing maintains the EMT3F package form factor to ensure mechanical compatibility without redesigning the printed circuit board layout.
