Overview
The PDTC143ZT,235 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a transistor with built-in bias resistors in a SOT23 surface-mounted package. Key electrical parameters include a collector-emitter voltage of 50 V and an output current capability of 100 mA. The internal input resistor R1 has a typical value of 4.7 kΩ, while the bias resistor ratio R2/R1 is typically 10. The device operates within a junction temperature range of -65 °C to 150 °C and features a total power dissipation of 250 mW at 25 °C ambient temperature.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count
- Qualified for automotive applications according to AEC-Q101 standards
- Provides high breakdown voltage and 100 mA output current capability
Applications
- Digital applications in industrial segments
- Cost-saving alternative for BC847 series in digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the component meets all relevant RoHS and REACH compliance requirements for the target market. Ensure the supplier provides valid traceability documentation consistent with Nexperia's quality standards.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The fixed resistor values eliminate external bias network components. Verify that the 50 V collector-emitter voltage rating exceeds the maximum operating voltage of the application circuit.
Part Context
This part belongs to the Nexperia Resistor-Equipped Transistor family designed for space-constrained designs. It serves as the NPN complement to the PDTA143ZT PNP variant. The device replaces discrete transistor and resistor combinations in standard SOT23 footprints.
Replacement Considerations
Direct functional substitutes include the PDTA143ZT for PNP logic inversion needs. Other RETs from the same manufacturer with identical pinouts and similar electrical ratings may serve as alternatives if resistor values align with design requirements.
