DTA114YUBTL

Overview

The DTA114YUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a supply voltage of -50V and supports a continuous collector current of -100mA. The device incorporates an input resistance (R1) of 10kΩ and an emitter-base resistance (R2) of 47kΩ, yielding a typical resistor ratio of 4.7. Key electrical parameters include a minimum DC current gain (hFE) of 68 at -5mA/-5V, a maximum operating frequency of 250MHz, and a power dissipation rating of 200mW. It is housed in the UMT3F (SOT-323FL) surface-mount package and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates internal biasing resistors to enable inverter circuit configuration without external input components.
• Provides simplified on/off control logic for digital switching applications.
• Utilizes a compact SMD package suitable for space-constrained surface mount designs.

Applications

• General-purpose digital switching circuits

• Low-voltage signal processing interfaces

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions remain within specified limits to maintain reliability. Cross-reference datasheet revisions to confirm pinout consistency. Validate thermal management requirements against calculated power dissipation limits during operation.

Selection Notes

Select this component for applications requiring a PNP digital transistor with integrated biasing. Compare R1 and R2 values against specific circuit impedance requirements. Evaluate the 200mW power dissipation limit against expected thermal loads. Consider the UMT3F package dimensions for PCB layout constraints. Verify compatibility with target voltage levels and switching frequencies.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from ROHM Semiconductor. The series offers complementary NPN options, such as the DTC114Y series. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity. The DTA114YUBTL specifically utilizes the UMT3F package variant.

Replacement Considerations

DTA114YUBHZG is listed as a similar specification alternative within the same product family. Both parts share identical electrical characteristics and polarity but may differ in packaging or ordering suffixes. Verify package compatibility before substitution.
