Overview
The BC846A-7-F is a single NPN small-signal bipolar junction transistor manufactured by Diodes Incorporated. It is housed in an SOT23 surface-mount package and designed for switching and audio frequency amplifier applications. The device features a collector-emitter voltage of 65V, a continuous collector current of 100mA, and a power dissipation of 310mW at 25°C. Electrical characteristics include a DC current gain (hFE) range of 110 to 220, a transition frequency of 300MHz, and an operating temperature range from -65°C to +150°C.
Feature Summary
- Designed for automatic insertion into manufacturing equipment
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green packaging
- Suitable for general-purpose switching and audio frequency amplification tasks
Applications
- General purpose switching circuits
- Audio frequency (AF) amplifier stages
- Portable electronic equipment
Procurement Notes
Verify the specific ordering suffix '-7-F' against official Diodes Incorporated documentation to confirm the 3,000-unit reel packing quantity and standard SOT23 marking code 'K1Q'. Ensure that the component meets the required environmental standards, specifically RoHS 3 compliance and the defined limits for halogen and antimony content as outlined in the manufacturer's quality definitions.
Selection Notes
Select this component when a low-voltage NPN transistor with moderate current handling is required for compact designs. The SOT23 package facilitates automated assembly processes. Consider the hFE binning (A grade: 110-220) for consistent gain performance in linear applications. Verify thermal constraints against the specified junction-to-ambient resistance values for the intended PCB copper layout.
Part Context
This part belongs to the BC846–BC848C series of NPN small-signal transistors. Complementary PNP types are available under the BC856A–BC858C designations. An automotive-compliant variant exists under the separate BC846AQ–BC848CQ datasheet. The series utilizes silicon technology and is encapsulated in a molded plastic SOT23 case with matte tin plated leads.
Replacement Considerations
Direct replacements within the same family include BC846B-7-F and BC846C-7-F, which share the identical SOT23 package but offer different DC current gain ranges. Cross-manufacturer equivalents must be verified for pinout compatibility and absolute maximum ratings.
