DTA023YEBTL

Overview

DTA023YEBTL is a PNP digital transistor with built-in resistors manufactured by Rohm Semiconductor. It features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. The device integrates an input resistor (R1) of 2.2 kΩ and an emitter-base resistor (R2) of 10 kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 35 at 5 mA and 10 V, a saturation voltage of 150 mV at 500 µA base and 5 mA collector currents, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW. The component is housed in an EMT3F (SOT-416FL) surface-mount package.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external input components.
• Provides high-speed switching capability with a transition frequency of 250 MHz.
• Offers low saturation voltage for efficient power management in digital logic applications.

Applications

• Inverter circuits requiring simplified input stages
• Digital logic interface buffers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure the selected variant matches the required tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The EMT3F package offers a compact footprint suitable for high-density PCB layouts. Consider the 2.2 kΩ input resistance value for appropriate drive current requirements and verify that the 100 mA collector current rating meets the load specifications of the target application.

Part Context

The DTA023YEBTL belongs to Rohm's standard digital transistor series, which combines bipolar junction transistors with internal bias resistors. This integration reduces component count and board space compared to discrete resistor-transistor combinations. The device is designed for general-purpose digital switching and logic interfacing tasks in various electronic systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other DTA023 variants with different resistor values. Verify that any substitute maintains the same polarity, voltage ratings, and package dimensions to ensure mechanical and electrical compatibility without redesigning the surrounding circuitry.
