Overview
The PDTC123TU-QX is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia, housed in a SOT-323 (SC-70) surface-mount package. It integrates a single NPN transistor with a built-in bias resistor R1 of 2.2 kΩ, while R2 remains open. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a collector-base voltage (VCBO) of 50 V, and an emitter-base voltage (VEBO) of 5 V. The device supports a continuous collector current of 100 mA with a power dissipation of 200 mW. It operates within a temperature range of -65°C to +150°C and holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Integrates a 2.2 kΩ bias resistor to simplify circuit design and reduce component count
- AEC-Q101 qualified for automotive digital applications
- Compact SOT-323 package reduces pick-and-place costs
Applications
- Digital switching in automotive and industrial segments
- Controlling IC inputs
- Switching loads as a cost-saving alternative to BC847 series
Procurement Notes
Verify the specific suffix 'QX' against the official Nexperia datasheet to confirm packaging details and compliance status. Ensure the order matches the required AEC-Q101 automotive grade specifications. Confirm availability through authorized distributors, as supply may be restricted in certain regions. Cross-reference the manufacturer part number with ECAD models for accurate footprint integration.
Selection Notes
Select this component when a compact NPN switch with integrated base biasing is required. The 2.2 kΩ internal resistor eliminates external bias components. Verify that the 50 V voltage rating and 100 mA current capacity meet the load requirements. Consider the SOT-323 package size constraints and thermal dissipation limits of 200 mW for the application environment.
Part Context
This part belongs to the PDTC123TU family of NPN resistor-equipped transistors. It serves as the automotive-grade variant (indicated by the 'Q' suffix) of the standard PDTC123TU. The PNP complement is the PDTA123TU. These devices are designed to replace discrete transistor-resistor networks in space-constrained digital circuits.
Replacement Considerations
The standard non-automotive equivalent is PDTC123TU,115. For PNP functionality, consider PDTA123TU. Higher voltage variants in the same package include NHDTC123JU (80 V). Verify pinout compatibility and thermal characteristics before substitution.
