DTC114EBT2L

Overview

The DTC114EBT2L is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50V and a continuous collector current of 50mA. The device includes a 10kΩ base resistor (R1) and a 10kΩ emitter-base resistor (R2), resulting in a resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 5mA and 5V, a transition frequency of 250MHz, and a power dissipation rating of 150mW. It is housed in the EMT3F (SOT-416FL) surface-mount package.

Feature Summary

• Integrates internal biasing resistors to eliminate external components for inverter configurations
• Provides high-speed switching capability with a 250MHz transition frequency
• Offers low saturation voltage for efficient signal processing

Applications

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

Procurement Notes

Verify the specific suffix BT2L against the official datasheet to confirm the EMT3F package type and tape-and-reel quantity. Ensure compatibility with RoHS3 standards if required by the target application. Cross-reference the manufacturer part number with distributor listings to confirm availability and lead times prior to ordering.

Selection Notes

Select this component when a compact NPN digital transistor with equal base and emitter-base resistors is required. The 10kΩ input impedance suits standard logic families. Consider the 150mW power dissipation limit and SOT-416FL thermal characteristics during PCB layout planning to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the ROHM DTx series of digital transistors, which combine bipolar junction transistors with integrated biasing networks. The DTC114EEBTL variant shares similar electrical characteristics but may differ in packaging or reel specifications. This series is designed to reduce board space and assembly complexity compared to discrete resistor-transistor combinations.

Replacement Considerations

Direct substitutes include other ROHM parts from the DTC114 family with matching R1/R2 values and NPN polarity. Verify pinout compatibility and thermal performance before replacing. Generic equivalents must match the 50V VCEO, 50mA Ic, and 10kΩ resistor configuration.
