Overview
The PDTC115EU-QX is a single NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates an NPN bipolar junction transistor with two internal bias resistors within a compact SOT323 (SC-70) surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 20 mA. Internal resistor values are specified as R1 = 100 kΩ and R2 = 100 kΩ, providing a typical resistance ratio of 1. The component is qualified to AEC-Q101 standards for automotive applications and operates across a temperature range from -55°C to +150°C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 reliability standards
- Integrated dual-bias resistor network simplifies circuit design
- Compact SOT323 plastic surface-mount packaging
Applications
- Automotive electronic control units
- Switching circuits in vehicle body electronics
- General-purpose digital logic interfacing
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm AEC-Q101 automotive qualification status. Ensure the ordering part number matches the required RoHS and REACH compliance declarations. Confirm package marking codes and reel specifications prior to procurement to avoid substitution errors.
Selection Notes
Select this component when a small-footprint NPN switch with integrated base biasing is required for automotive or high-reliability environments. The 100 kΩ input resistance suits moderate drive currents. Verify that the 20 mA collector current limit meets the load requirements. Consider the PNP complement PDTA115EU-QX if complementary polarity is needed.
Part Context
This part belongs to the Nexperia PDTCx15 series of pre-biased transistors designed for space-constrained applications. The 'Q' designation indicates automotive qualification, while 'EU' specifies the SOT323 package and pinout configuration. These devices replace discrete transistor-resistor combinations to reduce board space and assembly costs.
Replacement Considerations
Direct substitutes include the standard commercial grade PDTC115EU for non-automotive use. For equivalent automotive-grade performance, verify availability of other AEC-Q101 qualified RETs with matching 50V/20mA ratings and identical pin configurations.
