Overview
The BCP54-QX is an NPN medium power bipolar junction transistor manufactured by Nexperia. It features a collector-emitter breakdown voltage of 45 V and a continuous collector current capability of 1 A. The device operates with a transition frequency of 180 MHz and supports a maximum power dissipation of 650 mW. It is housed in a surface-mount SOT-223 package, also identified as TO-261AA. The component is qualified according to AEC standards for automotive applications.
Feature Summary
- Qualified according to AEC standards for automotive reliability
- High collector current capability for medium power switching
- Three distinct current gain selections available
Applications
- Automotive electronic systems
- General-purpose amplification
- Switching circuits
Procurement Notes
Verify the specific current gain bin (e.g., -16 suffix) required for your design, as the base part number may offer multiple gain ranges. Confirm that the SOT-223 footprint matches your PCB layout constraints. Ensure the supplier provides documentation confirming AEC qualification status if the application requires strict automotive compliance standards.
Selection Notes
Select this component when a robust NPN transistor with 45 V rating and 1 A current handling is needed in a compact surface-mount form factor. Consider the three available current gain options to optimize biasing requirements without external adjustments. Verify thermal management capabilities given the 650 mW dissipation limit in the SOT-223 package.
Part Context
This part belongs to the BCP54-Q series of NPN transistors designed for high-reliability environments. It shares electrical characteristics with other variants in the family but is distinguished by its specific packaging and automotive qualification level. The series offers standardized performance for consistent manufacturing outcomes across different production batches.
Replacement Considerations
Direct substitutes include the BCP54-16-QX variant which specifies a particular current gain range. Other generic NPN transistors with matching 45 V, 1 A ratings and SOT-223 packages may serve as functional alternatives if AEC qualification is not strictly required.
