DTA024XMT2L

Overview

The DTA024XMT2L is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal base resistor (R1) of 1 kΩ and an emitter-base resistor (R2) of 1 kΩ. Key electrical characteristics include a minimum DC current gain (hFE) of 56 at -5 mA and -10 V, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, housed in a compact SOT-723 (VMT3) surface-mount package suitable for automated assembly.

Feature Summary

• Integrates dual bias resistors (R1 and R2) directly within the package to reduce external component count and PCB space.
• Designed for high-speed switching applications with a transition frequency of 250 MHz.
• Utilizes a small-footprint SOT-723 (VMT3) surface-mount package for efficient board layout.

Applications

• General-purpose signal switching and level shifting in consumer electronics.
• Driver circuits for low-power loads in portable devices.
• Interface logic buffering between microcontrollers and peripheral components.

Procurement Notes

Verify the specific suffix MT2L against the official Rohm datasheet to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure compliance with RoHS directives as indicated in public documentation. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times prior to procurement planning.

Selection Notes

Select this component when a PNP digital transistor with equal 1 kΩ bias resistors is required. Compare hFE minimums and saturation voltages against alternative models if higher gain or lower drop is needed. Confirm that the 150 mW power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This part belongs to Rohm's standard digital transistor series, which combines NPN or PNP transistors with integrated bias resistors. The DTA024XMT2L specifically serves as a cost-effective solution for replacing discrete resistor-transistor networks in compact electronic designs.

Replacement Considerations

Publicly confirmed substitutes include the DTA024EMT2L and DTA024EUBTL from Rohm, which share similar electrical characteristics and pin configurations. Verify package compatibility and resistor values before substitution.
