BCP56-16H-QX

Overview

The BCP56-16H-QX is an NPN silicon epitaxial planar transistor manufactured by Nexperia, designed for general-purpose amplification and switching applications. It is housed in a SOT323 (SC-70) surface-mount plastic package. The device features a collector-emitter voltage of 80 V and a continuous collector current of 1 A. It includes an integrated base resistor with a resistance value of 4.7 kΩ, simplifying circuit design by reducing component count. The transistor operates within a temperature range of -55 °C to +150 °C and complies with RoHS standards.

Feature Summary

• Integrated base resistor eliminates the need for external biasing components
• High thermal stability supports operation up to 150 °C junction temperature
• Compact SOT323 surface-mount package optimizes PCB space utilization

Applications

• General-purpose signal amplification circuits
• Logic level shifting and interface buffering
• Switching applications in consumer electronics

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and reel specifications. Ensure compliance with automotive qualification requirements if the application demands AEC-Q100 certification, as standard variants may differ. Cross-reference pinout configurations with the official datasheet to prevent mounting errors during assembly.

Selection Notes

Select this component when a compact NPN transistor with built-in biasing is required for space-constrained designs. The integrated resistor reduces layout complexity compared to discrete transistors. Evaluate the 1 A current rating and 80 V breakdown voltage to ensure suitability for the target load conditions and operating voltages.

Part Context

This part belongs to Nexperia's family of biased resistor transistors (BRTs), which combine a single NPN or PNP transistor with one or two integrated resistors. These devices are engineered to simplify circuit design by minimizing the number of external components needed for biasing, thereby saving board space and reducing assembly costs.

Replacement Considerations

Compatible substitutes include other NPN BRTs with similar 4.7 kΩ base resistance and comparable voltage/current ratings from manufacturers such as Onsemi or Diodes Inc. Verify that alternative packages match the SOT323 footprint and that electrical characteristics align with the original specifications.
