- Provides complementary PNP types within the same series family.
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact packaging format and reel specifications. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a single NPN digital transistor with equal internal biasing resistors is required. Ensure the application voltage does not exceed the 50V limit and that the 100mA current capacity meets the load requirements.
Part Context
This part belongs to the DTC143E series of Bias Resistor Built-in Transistors. The series includes various packages such as SOT-723, SOT-323, and SOT-346, offering different power dissipation ratings and physical footprints while maintaining consistent electrical performance profiles.
Replacement Considerations
DTA143E series parts serve as complementary PNP replacements. Other DTC143 variants with different resistor values or packages may substitute if electrical parameters align with the design requirements.
