BC847BFAQ-7B

Overview

The BC847BFAQ-7B is a single NPN silicon small signal bipolar junction transistor manufactured by Diodes Incorporated. It is housed in an X2-DFN0806-3 surface-mount package with dimensions of 0.8mm x 0.6mm and a height of 0.4mm. The device supports a continuous collector current (IC) of 100mA and a peak pulse collector current (ICM) of 200mA. Key electrical ratings include a collector-emitter breakdown voltage (BVCEO) of 45V, a collector-base breakdown voltage (BVCBO) of 50V, and a maximum power dissipation (PD) of 435mW at 25°C ambient temperature. The transition frequency (fT) is specified at 100MHz.

Feature Summary

• Designed to meet stringent automotive application requirements with AEC-Q101 qualification for high reliability.
• Utilizes a compact X2-DFN0806-3 package that offers a significantly reduced footprint compared to traditional SOT-23 packages.
• Features a low-profile 0.4mm height design intended to minimize off-board component profile.
• Constructed using lead-free, halogen-free, and antimony-free green molding compounds compliant with RoHS directives.

Applications

• Automotive electronic circuits requiring high reliability components
• General-purpose switching applications
• RF amplifier stages within defined frequency limits

Procurement Notes

Verify the specific ordering suffix '-7B' corresponds to the 10,000-unit reel quantity configuration as documented in the manufacturer's ordering information. Confirm compliance with PPAP capabilities if required for automotive supply chain integration. Ensure procurement channels are authorized to maintain product integrity and traceability standards mandated by the supplier.

Selection Notes

Select this component when a compact surface-mount NPN transistor is required for automotive-grade environments. The X2-DFN0806-3 package is suitable for designs prioritizing minimal board space and low profile. Consider the 435mW power dissipation capability and thermal resistance characteristics relative to the PCB copper layout and operating temperature range of -55°C to +150°C.

Part Context

This part belongs to the BC847 series of small signal transistors produced by Diodes Incorporated. While standard variants utilize SOT-23 packaging, the BFAQ variant specifically employs the X2-DFN0806-3 form factor. This series includes complementary PNP types such as the BC857BFA. The FAQ designation indicates adherence to automotive quality standards distinct from general commercial grade counterparts.

Replacement Considerations

The datasheet identifies the BC857BFA as the complementary PNP type within the same family. Direct pin-compatible replacements in alternative packages require verification of electrical parameters and thermal characteristics against the original design constraints.
