DTC114YEBTL

Overview

The DTC114YEBTL 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 internal resistor configuration consists of R1 at 10 kΩ and R2 at 47 kΩ, yielding a resistance ratio of approximately 4.7. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 5 mA/5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. The device supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Integrates bias resistors (R1=10kΩ, R2=47kΩ) to simplify circuit design by eliminating external components.
• Provides high-speed switching capability with a transition frequency of 250 MHz.
• Offers robust thermal performance with a maximum junction temperature rating of 150 °C.

Applications

• General-purpose inverter circuits requiring simplified input biasing.
• Logic level translation between microcontrollers and peripheral devices.
• Switching applications in consumer electronics and industrial control systems.

Procurement Notes

Verify the specific suffix 'ETL' against the manufacturer's latest datasheet to confirm packaging details and availability status. Ensure compatibility with RoHS directives if required for the target market. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the EMT3F package dimensions match the PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a compact NPN solution with fixed bias ratios is needed. Compare hFE minimums and leakage currents against alternative models like DTC114YE or DTC114EEBTL based on specific gain requirements. Consider the SOT-416FL package size constraints relative to other available digital transistor families. Evaluate thermal management needs given the 150 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to ROHM's standard digital transistor series, designed to replace discrete resistor-transistor combinations. It simplifies layout and reduces assembly costs by integrating biasing networks. The DTC114YEBTL serves as the NPN counterpart to PNP variants such as the DTA114YEBTL, offering complementary functionality for push-pull or differential configurations.

Replacement Considerations

Direct substitutes include DTC114YE and DTC114YETL, which share similar electrical characteristics but may differ in packaging or specific parameter tolerances. Verify pinout compatibility and thermal resistance values when replacing with cross-brand equivalents. Consult manufacturer substitution guides for validated alternatives ensuring identical functional performance.
