Overview
The DTA143EUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an internal base resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 4.7kΩ, providing a typical resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 30 at -5mA and -5V, a maximum operating frequency of 250MHz, and a power dissipation rating of 200mW. It is housed in a compact SOT-323FL-3 surface-mount package.
Feature Summary
- Integrated biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
- High-speed switching capability supports operation up to 250MHz for efficient signal processing.
- Compact SOT-323FL-3 packaging facilitates high-density surface-mount assembly.
Applications
- Inverter circuits requiring simplified input stages
- General-purpose switching applications in consumer electronics
- Driver circuits for low-power loads
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Review datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when a PNP digital transistor with equal 4.7kΩ internal resistors is required. Ensure the -50V voltage rating and -100mA current capacity align with load conditions. Consider the SOT-323FL-3 footprint constraints during PCB layout planning.
Part Context
This part belongs to the DTA143EUB series of pre-biased transistors from ROHM Semiconductor. It serves as a standard discrete semiconductor solution for replacing multiple discrete components with a single integrated device, reducing board space and assembly complexity in modern electronic designs.
Replacement Considerations
DTA143EU3T106 is listed as a similar specification replacement within the same product family, offering comparable electrical performance in a UMT3 package.
