Overview
The DTA143EUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-323 surface-mount package. It integrates thin-film bias resistors to simplify circuit design. Key electrical parameters include a maximum supply voltage of -50 V, a collector current of -100 mA, and a power dissipation of 200 mW. The typical input resistance (R1) is 4.7 kΩ with a resistance ratio (R2/R1) of 1.0. The device features a transition frequency of 250 MHz and a minimum DC current gain of 30.
Feature Summary
- Built-in bias resistors enable inverter configuration without external input resistors
- Thin-film resistors provide complete isolation for negative biasing capability
- Eliminates parasitic effects associated with discrete resistor networks
Applications
- Inverter circuits requiring simplified input stages
- Switching applications where on/off conditions are primary operational requirements
- Digital logic interface circuits utilizing pre-biased configurations
Procurement Notes
Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unauthorized sources lack traceability and quality assurance guarantees. Confirm RoHS compliance status via official documentation prior to integration into regulated assemblies.
Selection Notes
Select this component for designs requiring a compact PNP digital solution with integrated biasing. Ensure the -50 V supply voltage rating and -100 mA current capacity align with system constraints. The SOT-323 package is suitable for space-constrained surface-mount layouts.
Part Context
This part belongs to the DTA143 series of single PNP digital transistors. It is distinct from NPN variants like the DTC143 series and other packages such as SOT-23. The device marking is '13'.
Replacement Considerations
Cross-reference with other PNP digital transistors in SOT-323 packages having similar R1 values and voltage ratings. Verify pinout compatibility and electrical characteristics before substitution.
