Overview
The DTA143ZEFRATL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3 (SOT-416) surface-mount package. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes a typical input resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 47kΩ, yielding a resistance ratio of 10. Key electrical parameters include a minimum DC current gain (hFE) of 80 at -10mA and -5V, a maximum operating frequency of 250MHz, and a power dissipation rating of 150mW. It supports AEC-Q101 automotive standards and functions within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates thin-film bias resistors to simplify inverter circuit design without external components.
- Resistor isolation allows positive input biasing while minimizing parasitic effects.
- Complies with AEC-Q101 automotive grade reliability standards.
Applications
- Inverter circuits
- Interface logic drivers
- Automotive electronic control units
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the component meets AEC-Q101 requirements if deployed in automotive applications. Cross-reference the exact part number with authorized distributors to confirm current supply status and RoHS compliance details before procurement.
Selection Notes
Select this component for designs requiring a compact PNP digital transistor with integrated biasing. The SOT-416 package suits space-constrained PCB layouts. Verify that the 4.7kΩ input resistance aligns with the driving source impedance. Confirm thermal management capabilities for the 150mW power dissipation limit under expected operating conditions.
Part Context
This part belongs to the DTA143 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to the NPN DTC143Z series. The device simplifies switching applications by combining a bipolar junction transistor with internal resistive networks, reducing board space and assembly complexity compared to discrete resistor-transistor combinations.
Replacement Considerations
DTA143ZU3HZGTL offers identical pinout and package compatibility. Both parts share similar electrical characteristics and automotive qualification status. Verify specific suffix variations for packaging differences when substituting.
