DTA023EUBTL

Overview

The DTA023EUBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a supply voltage of 50 V and supports a continuous collector current of 100 mA. The device includes an internal resistor network with R1 and R2 both valued at 2.2 kOhms. Key electrical parameters include a minimum DC current gain (hFE) of 20 at 20 mA and 10 V, a maximum transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The saturation voltage is specified as a maximum of 250 mV under test conditions of 1 mA base current and 10 mA collector current.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Surface-mount construction in a compact EMT3F package facilitates automated assembly and space-constrained layouts.

Applications

• Inverter circuits requiring simplified input stages
• Switching applications in portable electronic devices
• Logic interface buffering between microcontrollers and loads

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and specific packaging configurations such as tape and reel quantities prior to procurement. Ensure storage conditions adhere to specified temperature ranges to maintain device integrity during handling and installation processes.

Selection Notes

Select this component when a PNP digital transistor with matched 2.2 kOhm biasing resistors is required. Verify that the 50 V collector-emitter voltage and 100 mA current ratings align with load requirements. Consider the 150 mW power dissipation limit and thermal management needs within the SOT-416FL footprint constraints.

Part Context

This part belongs to the DTA023 series of pre-biased transistors from ROHM Semiconductor. It serves as the PNP counterpart to NPN digital transistor variants within the same product family. The series is designed for general-purpose switching and logic interfacing applications where board space and component count reduction are prioritized.

Replacement Considerations

Direct substitutes must match the PNP polarity, 50 V rating, 100 mA current capacity, and identical 2.2 kOhm/2.2 kOhm internal resistor values. Verify pinout compatibility and package dimensions for the EMT3F/SOT-416FL form factor before implementation.
