BC846BQ-7-F

Overview

The BC846BQ-7-F is an NPN surface-mount small signal transistor manufactured by Diodes Incorporated. It is housed in the SOT-23 package and designed for general-purpose switching and amplification applications. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. Key electrical parameters include a DC current gain (hFE) range corresponding to the 'B' suffix, typically between 110 and 200 at specified test conditions. The component operates within a junction temperature range of -55°C to +150°C and offers low saturation voltage characteristics suitable for portable equipment.

Feature Summary

• NPN polarity configuration optimized for low-voltage general-purpose applications
• Ultra-small SOT-23 surface-mount encapsulation for space-constrained designs
• Low saturation voltage capability for efficient power management
• High DC current gain performance across standard operating ranges

Applications

• General purpose switching circuits
• Amplifier stages in portable consumer electronics
• Signal processing in battery-powered devices
• Logic level translation interfaces

Procurement Notes

Verify the specific hFE binning associated with the 'B' suffix against the official Diodes Incorporated datasheet prior to integration. Confirm that the SOT-23 footprint matches the target PCB layout dimensions. Ensure compliance with RoHS directives if required by the end-product specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this component when a compact NPN transistor with moderate current handling is required. The SOT-23 package provides a balance between thermal performance and board space efficiency. Consider the 'B' gain bin if specific amplification factors are necessary for the circuit design. Evaluate the 65V breakdown voltage to ensure it meets the system's peak voltage requirements without excessive derating.

Part Context

This component belongs to the BC846 series of NPN small signal transistors produced by Diodes Incorporated. The series is widely utilized in consumer electronics due to its reliability and small form factor. The 'Q' suffix often indicates automotive or qualified grade variants, though verification against the specific datasheet is recommended. The '-7-F' designation typically refers to tape and reel packaging with lead-free finish.

Replacement Considerations

Direct substitutes include other BC846B variants from different manufacturers such as BC846B-7 or BC846BW, provided the pinout and electrical ratings match. Verify package compatibility and thermal characteristics before substitution.
