Overview
The BC848B-7-F is an NPN small-signal transistor manufactured by Diodes Incorporated, housed in a SOT23 surface-mount package. It features a collector-emitter voltage of 30V and a continuous collector current of 100mA. The device provides a minimum DC current gain (hFE) of 200 at IC=2.0mA and VCE=5V. Electrical characteristics include a transition frequency of 100MHz and a power dissipation rating of 310mW under standard conditions.
Feature Summary
- Designed for switching and audio frequency amplifier applications
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green packaging
- Ideally suited for automatic insertion processes
Applications
- General purpose switching circuits
- Audio frequency amplifiers
Procurement Notes
Verify the specific ordering suffix '-7-F' to confirm the 3,000-unit reel packing quantity and K1R marking code. Ensure compliance requirements match project specifications, as this part is fully RoHS compliant and free from intentionally added lead, bromine, chlorine, and antimony compounds.
Selection Notes
Select this component when a low-voltage NPN transistor with moderate current handling is required. The BC848B variant offers a higher minimum DC current gain compared to the 'A' version, making it suitable for applications requiring consistent amplification factors without excessive base drive current.
Part Context
This part belongs to the BC846A–BC848C series of NPN small-signal transistors. The series includes complementary PNP types (BC856A–BC858C). An automotive-compliant version is available separately under the BC846AQ–BC848CQ datasheet designation.
Replacement Considerations
Compatible substitutes within the same family include BC848A-7-F and BC848C-7-F. These parts share identical physical packages and maximum ratings but differ in their specified DC current gain ranges.
FAQ
What is the marking code on the BC848B-7-F package?
The top-side marking code for the BC848B-7-F is K1R.
Is there an automotive-grade version of this transistor?
Yes, an automotive-compliant part is available under the separate BC846AQ–BC848CQ datasheet.
What are the ESD protection ratings for this device?
The device supports 4,000V Human Body Model (JEDEC Class 3A) and 400V Machine Model (JEDEC Class C) electrostatic discharge.
