Overview
The PDTB123YU-QX is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates a single NPN transistor with built-in biasing resistors into a compact SOT-323 (SC-70) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a maximum collector-base voltage (VCBO) of 50 V, and a maximum emitter-base voltage (VEBO) of 5 V. The device supports a continuous collector current of 100 mA and handles a power dissipation of 200 mW. It operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates NPN transistor with built-in biasing resistors to simplify circuit design
- Reduces component count and pick-and-place costs in digital applications
- Suitable for controlling IC inputs and switching loads
Applications
- Digital logic interface circuits
- IC input control stages
- Load switching applications
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and compliance status. Ensure the procurement channel provides valid traceability for automotive-grade components if required by the application specifications.
Selection Notes
Select this component when space constraints require a combined transistor and resistor solution in an SOT-323 package. Confirm that the 50 V voltage rating and 100 mA current capability meet the circuit requirements. Verify compatibility with automated assembly processes due to the small surface-mount form factor.
Part Context
This part belongs to the PDTB series of NPN resistor-equipped transistors from Nexperia. It serves as a discrete alternative to complex biasing networks, offering a standardized solution for digital switching tasks where board space and assembly efficiency are critical design factors.
Replacement Considerations
Check for direct equivalents such as the PDTA123YU (PNP complement) or other RETs in the same SOT-323 package family. Verify pinout compatibility and electrical parameter alignment before substitution.
