Overview
The BC846AMTF is an NPN epitaxial silicon transistor manufactured by onsemi, housed in a SOT-23 surface-mount package. It supports a maximum collector current of 100 mA and features a collector-emitter voltage rating of 65 V with a collector-base voltage of 80 V. The device offers a power dissipation capacity of 310 mW and a gain-bandwidth product of 300 MHz. Operating temperatures range from -65°C to +150°C junction temperature. The 'A' suffix indicates a DC current gain classification of 110 to 220, while the 'M' suffix denotes the SOT-23 package and 'TF' specifies tape and reel packing.

Procurement Notes
Verify the specific hFE binning requirements against the datasheet classification table before procurement. Confirm that the SOT-23 footprint matches the target PCB layout. Ensure the tape and reel packaging aligns with automated assembly equipment specifications. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and traceability.
Selection Notes
Select this component when a general-purpose NPN transistor with moderate voltage ratings and high-frequency response is required. The BC846 series provides a complement to the BC856 family. Consider the specific hFE classification needed for the application, as the 'A' variant covers a lower gain range compared to 'B' or 'C' variants. Evaluate thermal resistance constraints for the intended operating environment.
Part Context
This component belongs to the BC846/BC847/BC848/BC850 family of NPN epitaxial silicon transistors. These devices are widely used in consumer electronics and industrial control systems. The BC846 specifically targets applications requiring higher voltage tolerance than the BC847 or BC848 variants. The SOT-23 package allows for compact board designs.
Replacement Considerations
Direct substitutes include BC846ALT3G and BC846A/SNR. Verify pinout compatibility and electrical parameter overlaps, particularly regarding collector-emitter voltage and current gain ranges, before substituting.
