Overview
The PDTC144EU-Q is an NPN Resistor-Equipped Transistor (RET) housed in a compact SOT323 (SC-70) surface-mounted plastic package. It integrates bias resistors to simplify circuit design and reduce component count. The device supports a collector-emitter voltage of 50 V and an output current capability of 100 mA. Key electrical parameters include a typical input bias resistor (R1) of 47 kΩ, a bias resistor ratio (R2/R1) of 1, and a DC current gain (hFE) minimum of 80 at 5 mA. It operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Built-in bias resistors that simplify circuit design and reduce component count
- Qualified according to AEC-Q101 for automotive applications
- Compact SC-70 (SOT323) surface-mounted package
Applications
- Digital applications in automotive and industrial segments
- Cost-saving alternative for BC847-Q series in digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape width. Confirm RoHS compliance status and lead times directly with authorized distributors prior to placing orders. Ensure the procurement channel provides valid traceability documents required for automotive-grade components.
Selection Notes
Select this component when a small footprint NPN transistor with integrated biasing is required for space-constrained designs. Verify that the 50 V collector-emitter voltage and 100 mA current ratings align with the target application's electrical requirements. Consider the AEC-Q101 qualification if the deployment environment demands automotive reliability standards.
Part Context
This part belongs to Nexperia's portfolio of NPN Resistor-Equipped Transistors designed to replace discrete resistor-transistor networks. It serves as a direct functional equivalent to standard small-signal transistors but offers reduced board space and assembly costs due to the integrated biasing network.
Replacement Considerations
The PDTA144EU is the PNP complement within the same family. For direct pin-compatible replacements in existing designs, verify datasheet compatibility with other RETs in the SC-70 package from various manufacturers.
