PDTB143EU-QX

Overview

The PDTB143EU-QX is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Nexperia. It integrates internal base and emitter resistors within a single SOT-323 (SC-70) surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of 50 V, a continuous collector current of 100 mA, and a maximum power dissipation of 250 mW. The device operates across an extended temperature range from -65°C to +150°C. This component is designed for applications requiring simplified biasing circuits and space-efficient packaging.

Feature Summary

Integrated dual-resistor network eliminates external bias components
Automotive-grade qualification compliant with AEC-Q101 standards
Compact SOT-323 surface-mount footprint for high-density PCB layouts

Applications

Switching applications in automotive electronic control units
Driver circuits for low-power loads in industrial automation
Biasing stages in portable consumer electronics

Procurement Notes

Verify the specific suffix configuration against official Nexperia documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q101 automotive qualification aligns with target application requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. Ensure the 100 mA current rating and 50 V voltage limits accommodate the circuit load. Verify thermal management capabilities given the 250 mW power dissipation limit in the small SOT-323 package.

Part Context

This part belongs to the PDTB series of pre-biased transistors from Nexperia. It shares functional similarities with other members like PDTC143EU but differs in polarity (PNP vs NPN) and specific resistor values. The QX suffix typically denotes automotive-grade variants with enhanced reliability standards compared to standard commercial versions.

Replacement Considerations

Direct substitutes may include PDTB143E or PDTB143ET if package compatibility is maintained. Verify equivalent resistor ratios and current ratings. Cross-reference with PDTC143EU only if circuit polarity inversion is acceptable.
