Overview
The PDTD123YU-QX is a digital NPN transistor manufactured by Nexperia, housed in the SOT-323 (SC-70) surface-mount package. It integrates an NPN bipolar junction transistor with two built-in base resistors to simplify circuit design and reduce component count. The device features 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. It supports a continuous collector current of 100 mA with a power dissipation of 200 mW. The unit operates within a temperature range of -65°C to +150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Integrated dual base resistor network for simplified biasing
- Automotive-grade reliability compliant with AEC-Q101 standards
- Compact SOT-323 surface-mount packaging for high-density applications
Applications
- Switching applications in automotive electronic control units
- Level shifting and logic interface circuits
- General-purpose switching in consumer electronics
Procurement Notes
Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm it denotes the standard reel or cut-tape packaging format. Ensure the part number matches the exact electrical specifications required for your design, as minor suffix variations may indicate different packaging quantities or tape-and-reel configurations. Cross-reference the ordering code with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a compact NPN digital switch with integrated biasing is required for space-constrained designs. The 50 V rating suits low-voltage logic interfaces, while the AEC-Q101 qualification makes it suitable for automotive environments. Compare its 200 mW power dissipation and 100 mA current limits against load requirements to ensure adequate thermal headroom under operating conditions.
Part Context
This part belongs to Nexperia’s portfolio of pre-biased digital transistors designed to replace discrete resistor-transistor combinations. The 'PD' prefix indicates a PNP digital transistor, but the model specifies NPN polarity, requiring careful verification of the datasheet schematic. The 'TU' typically refers to the SOT-323 package, while 'Q' signifies automotive qualification.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified NPN digital transistors in SOT-323 packages with similar 50 V ratings and integrated resistors, such as the PDTC123 series from compatible manufacturers. Verify pinout compatibility and internal resistor values before substitution.
