Single Bipolar Transistors datasheet and documents for BC546B

BC546B

Single Bipolar Transistors Overview

The BC546B is a general-purpose NPN silicon epitaxial transistor manufactured by Diotec Semiconductor. It operates with a maximum collector current of 100 mA and a collector-emitter voltage (VCEO) of 65 V. The device features a DC current gain (hFE) group B rating, ranging from 200 to 450 at IC = 2 mA. Key electrical parameters include a transition frequency (fT) of 300 MHz, power dissipation of 500 mW, and a collector-emitter saturation voltage of 600 mV at IC = 100 mA. It supports junction temperatures up to 150°C and utilizes a TO-92 through-hole package.

Single Bipolar Transistors Feature Summary

Three distinct DC current gain groups for precise amplification control
Low noise figure suitable for sensitive signal processing applications
Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Bipolar Transistors Applications

Signal processing circuits
Electronic switching applications
General-purpose amplification stages

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the official Diotec datasheet to confirm compliance requirements. Confirm that the component matches the standard commercial/industrial grade unless an AEC-Q101 variant is explicitly required. Ensure the TO-92 package dimensions align with the target PCB layout constraints before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a 65 V breakdown voltage and 100 mA continuous current are required. The Group B hFE range (200–450) provides higher gain than Group A variants. Consider the BC547 or BC548 if lower voltage ratings are acceptable. Verify thermal resistance limits relative to ambient temperature conditions in the final assembly design.

Single Bipolar Transistors Part Context

This part belongs to the BC546...BC549 series of universal NPN transistors. It serves as a standard replacement for legacy small-signal NPN devices in consumer electronics and industrial control systems. The BC546B specifically offers higher voltage tolerance compared to the BC548 or BC549 series while maintaining similar current handling capabilities.
