BCP56F

Overview

The BCP56F is a dual NPN bipolar junction transistor (BJT) array manufactured by Nexperia. It is housed in a SOT223 (SC-73) surface-mount package, designed for compact circuit layouts. The device features two independent NPN transistors within a single component, offering a collector current of up to 100 mA and a maximum collector-emitter voltage of 80 V. With a transition frequency of 250 MHz and a power dissipation rating of 500 mW, it supports high-speed switching applications. The 'F' suffix indicates specific tape and reel packaging for automated assembly processes.

Feature Summary

• Dual NPN configuration providing two independent switching elements in one package
• High-speed operation capability suitable for signal processing and logic interfacing
• Robust thermal performance with 500 mW power dissipation in a compact SOT223 footprint

Applications

• General-purpose switching circuits
• Logic level translation and buffering
• Driver stages for low-power loads

Procurement Notes

Verify the exact ordering code against the manufacturer's official datasheet to ensure correct packaging and electrical specifications. Confirm that the SOT223 package dimensions align with your PCB layout constraints. Check for any specific automotive or industrial qualification requirements if the application demands high reliability standards beyond standard commercial grade.

Selection Notes

Select this component when space-saving dual NPN configurations are required. The SOT223 package offers superior thermal handling compared to smaller SMD packages like SOT23. Ensure the 80 V voltage rating meets the circuit's peak operating conditions. Consider the 100 mA current limit for load driving capabilities before finalizing the design.

Part Context

This part belongs to Nexperia's extensive portfolio of discrete bipolar transistors. The BCP56 series is widely used in consumer electronics and industrial control systems where reliable switching is essential. Nexperia provides comprehensive documentation and support resources for integrating these components into various electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers such as ON Semiconductor or STMicroelectronics. Verify that substitute parts match the 80 V rating, 100 mA current capacity, and SOT223 package outline to ensure seamless integration without redesigning the PCB.
