BC856BMBYL

Overview

The BC856BMBYL is a PNP general-purpose transistor manufactured by Nexperia. It features a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device is housed in an ultra-small DFN1110D-3 (SOT8015) leadless Surface-Mounted Device plastic package with side-wettable flanks, measuring 1.1 mm x 1.0 mm x 0.5 mm. This component serves as the B-grade variant within the BC856 series, offering specific DC current gain characteristics suitable for low-voltage, low-current applications.

Feature Summary

• Ultra-small footprint design optimized for space-restricted surface-mounted applications
• Side-wettable flanks facilitate Automatic Optical Inspection of solder joints
• Low package height of 0.5 mm supports compact electronic device construction

Applications

• General-purpose switching circuits
• Signal amplification stages
• Space-constrained consumer electronics

Procurement Notes

Verify the exact suffix 'MBYL' against official Nexperia documentation to confirm it corresponds to the BC856B specification in the SOT8015 package. Ensure the ordering code matches the manufacturer's current naming conventions, as suffixes often denote tape-and-reel quantities or specific manufacturing batches rather than functional differences.

Selection Notes

Select this component when a small form factor is required alongside standard PNP switching capabilities. The BC856B offers defined hFE ranges compared to the unlettered BC856. Consider the DFN1110D package for thermal efficiency and PCB area savings compared to traditional SOT23 packages while maintaining compatible pinout functionality for many designs.

Part Context

This part belongs to the Nexperia BC856 family of PNP general-purpose transistors. The family includes variants like BC856A, BC857, and BC858, differentiated primarily by their DC current gain (hFE) bins. The BC856B specifically targets applications requiring moderate gain consistency. The NPN complement for this device is the BC846B.

Replacement Considerations

Official pin-to-pin replacements include the BC856B without the MBYL suffix if the packaging format differs. Other valid substitutes within the same electrical specifications are the BC856B in SOT23 packages (e.g., BC856B,215) or the BCM856BSH for matched double transistor requirements.
