Overview
The BC846ALT1 is an NPN silicon general-purpose transistor from the BC846ALT1 series, manufactured by onsemi. It features a collector-emitter voltage (VCEO) of 65 V and a collector-base voltage (VCBO) of 80 V. The device supports a continuous collector current of 100 mA with a maximum power dissipation of 225 mW in an SOT-23 package. Key electrical characteristics include a DC current gain (hFE) ranging from 110 to 220 at IC = 10 µA, and a transition frequency (fT) of 100 MHz. Operating temperatures range from -55°C to +150°C.
Feature Summary
- General-purpose NPN silicon transistor designed for standard switching and amplification applications
- High ESD protection capability exceeding 4000 V under Human Body Model standards
- Moisture sensitivity level 1 classification suitable for standard surface mount assembly processes
Applications
- General purpose switching circuits
- Amplifier stages
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details such as tape and reel specifications. Confirm that the component meets Pb-Free requirements if applicable to the design constraints. Ensure the selected variant matches the required hFE binning and thermal performance parameters for the intended operating environment.
Selection Notes
Select this component when a general-purpose NPN transistor with a 65 V collector-emitter rating is required. The SOT-23 package provides a compact footprint for surface mount designs. Consider the 100 mA continuous current limit and 225 mW power dissipation capabilities during thermal management planning. Verify compatibility with the target application's voltage and current requirements.
Part Context
This part belongs to the BC846ALT1 series, which includes variants like BC847 and BC848 differentiated primarily by their breakdown voltages. The 'ALT1' designation indicates a specific hFE binning and packaging configuration within the broader BC846 family. These transistors are classified as Preferred Devices by onsemi, indicating recommended choices for future use.
Replacement Considerations
BC846BLT1G serves as a direct functional replacement within the same series, offering identical pinout and electrical ratings but potentially different hFE binning or packaging options.
