BC847B-C

Overview

The Diotec Semiconductor BC847B-C is a surface-mount general-purpose NPN bipolar junction transistor housed in an SOT-23 package. It features a collector-emitter voltage of 45 V, a continuous collector current of 100 mA, and a power dissipation of 200 mW for the commercial grade. The device belongs to the Group B current gain category, providing a DC current gain range of 180 to 290 at a collector current of 2 mA. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Utilizes copper bond wires specific to the commercial grade variant
• Provides three distinct current gain groups for standardized amplification applications
• Complies with RoHS directives without exemptions and adheres to REACH regulations

Applications

• Signal processing circuits
• Electronic switching applications
• General-purpose amplification stages

Procurement Notes

Verify that the component matches the exact BC847B-C designation to ensure the correct 45V rating and Group B gain characteristics. Confirm the presence of the -C suffix indicates the commercial grade with specified 200mW dissipation limits. Ensure compliance requirements such as RoHS and REACH are documented for your specific supply chain needs before finalizing orders.

Selection Notes

Select this component when a 45V NPN transistor with moderate gain is required for standard commercial environments. The -C suffix denotes the commercial grade which utilizes copper bond wires instead of gold. Consider the lower power dissipation limit compared to industrial grades when designing thermal management strategies for high-density PCB layouts.

Part Context

This part belongs to the BC846 through BC850 series of SMD universal NPN transistors manufactured by Diotec Semiconductor. The series offers various voltage ratings and gain groupings across different packages. The BC847 variant specifically provides a 45V breakdown voltage, distinguishing it from the higher-voltage BC846 or lower-voltage BC848 models within the same family.

FAQ

What distinguishes the BC847B-C from other gain groups?

The 'B' suffix designates the Group B current gain classification, which specifies a DC current gain range of 180 to 290 at IC = 2 mA.

How does the commercial grade affect power dissipation?

The commercial grade (-C) has a maximum power dissipation of 200 mW, whereas industrial and AEC-Q101 grades support up to 300 mW under similar mounting conditions.

What type of bond wires are used in this component?

The commercial grade version (indicated by the -C suffix) uses copper bond wires, while all other grades in the series utilize gold bond wires.
