Overview
The DTA044EMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within an SMD/SMT package. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes typical input resistance values of 1kΩ and 47kΩ, with a DC current gain (hFE) minimum of 35 at -5mA and -10V. It supports a maximum operating frequency of 250MHz and has a power dissipation rating of 150mW. The component is housed in a compact SOT-723-3 (VMT3) package, suitable for surface mount applications.
Feature Summary
- Integrates biasing resistors to simplify circuit design
- Compact SOT-723-3 surface mount package
- High-speed operation up to 250MHz
- PNP polarity configuration
Applications
- General-purpose switching circuits
- Inverter logic gates
- Driver circuits for low-power loads
Procurement Notes
Verify the specific suffix 'T2L' against the manufacturer's datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with standard SMT pick-and-place equipment for the VMT3 package. Confirm RoHS compliance status through official documentation before procurement.
Selection Notes
Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The 1kΩ/47kΩ resistor ratio suits general switching applications. Verify that the -50V collector-emitter voltage meets the system requirements. Consider thermal management for the 150mW power dissipation limit in enclosed environments.
Part Context
This part belongs to the DTA044 series of digital transistors from ROHM Semiconductor. These devices are designed to replace discrete transistor-resistor combinations, reducing board space and assembly costs. The DTA044EMT2L specifically utilizes the VMT3 package, offering a small footprint for high-density PCB layouts.
Replacement Considerations
Check for direct substitutes like DTA044EEBTL if different pinout or electrical characteristics are needed. Verify equivalent packages such as SOT-416 for mechanical fit. Ensure replacement parts maintain similar hFE and saturation voltage specifications.
