DTA114YEBTL

Overview

The DTA114YEBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an input resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms. Key electrical parameters include a DC current gain (hFE) of at least 68 at -5 mA and -5 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. It is housed in an EMT3F (SOT-416FL) surface-mount package.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• High-speed switching capability supported by a 250 MHz transition frequency for efficient signal processing.
• Compact SMD packaging facilitates automated surface-mount assembly and space-constrained board layouts.

Applications

• General-purpose logic level shifting and interface circuits
• Driver stages for relays, solenoids, or small motors
• Switching applications in consumer electronics and industrial control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and flammability ratings required for your assembly process. Check for any end-of-life notices or recommended replacement parts if sourcing for long-term production runs.

Selection Notes

Select this component when a PNP digital transistor with a 10k/47k resistor ratio is required. Ensure the -50V voltage rating and -100mA current capacity meet the load requirements. Consider the EMT3F package dimensions for PCB footprint compatibility and verify thermal dissipation needs within the 150mW limit.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from ROHM. It serves as a standard-grade discrete solution for replacing multiple discrete components. The complementary NPN version is the DTC114Y series. This specific variant uses the EMT3F package, distinct from other automotive or high-reliability variants in the broader family.

Replacement Considerations

Direct substitutes include the DTA114YE and DTA114YETL. Verify pinout and package dimensions match before substitution. For automotive applications, consider the AEC-Q101 qualified DTA114YE3HZG instead.
