DTA023EEBTL

Overview

The DTA023EEBTL is a pre-biased PNP digital transistor manufactured by Rohm Semiconductor. It integrates bias resistors R1 and R2, both valued at 2.2 kOhms, into a single surface-mount package to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 50 V, a continuous collector current (Ic) of 100 mA, and a power dissipation rating of 150 mW. The device features a DC current gain (hFE) of at least 20 at Ic=20mA and Vce=10V, with a saturation voltage (Vce(sat)) of 250 mV max at Ic=10mA. It operates with a transition frequency (fT) of 250 MHz and is housed in an EMT3F (SOT-416FL/SC-89) package.

Feature Summary

• Integrates built-in bias resistors (R1=R2=2.2kΩ) to eliminate external input components
• Enables simple inverter circuit configuration by requiring only on/off signal settings
• Provides high-speed switching capability with a 250 MHz transition frequency

Applications

• Inverter circuits for logic level translation
• Driver circuits for small-signal switching applications
• General-purpose digital interface buffering

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and resistor values. Ensure the selected variant matches the required EMT3F packaging format. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for low-current switching. The 2.2 kOhm internal resistor ratio suits standard logic interfaces. Consider the 150 mW power dissipation limit and SOT-416FL thermal characteristics during PCB layout. Verify that the 50 V voltage rating meets the system's maximum operating conditions.

Part Context

This part belongs to Rohm's DTA series of digital transistors, which are designed to replace discrete BJT configurations with built-in bias networks. The DTA023EEBTL specifically addresses applications needing simplified schematic designs and reduced board space. It serves as a direct replacement for discrete PNP transistors paired with external base resistors in consumer electronics and industrial control modules.

Replacement Considerations

Direct substitutes within the same family include DTA023EUBTL or DTA023EBTL, provided the package and electrical specifications remain identical. Verify equivalent resistor values and hFE ranges before substitution.
