BC546C B1G

Single Bipolar Transistors Overview

The BC546C B1G is an NPN silicon epitaxial planar transistor manufactured by Taiwan Semiconductor Corporation. It belongs to the BC546 series, characterized by a collector-emitter voltage (VCEO) of 65 V and a continuous collector current (IC) of 100 mA. The device features a minimum DC current gain (hFE) of 200 at IC = 2 mA and VCE = 5 V. It operates within a junction temperature range of -55°C to +150°C and dissipates up to 500 mW in a TO-92 package.

Single Bipolar Transistors Feature Summary

• High DC current gain with a minimum hFE of 200 for signal amplification
• Robust voltage handling capability with 65 V collector-emitter breakdown
• Wide thermal operating range suitable for diverse environmental conditions

Single Bipolar Transistors Applications

• General-purpose small-signal amplification circuits
• Electronic switching applications requiring moderate voltage levels
• Audio pre-amplifier stages in consumer electronics

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'B1G' against the manufacturer's official datasheet to confirm packaging details and pinout configuration. Ensure the component meets RoHS compliance requirements if applicable to your design. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-power amplification tasks. The BC546C variant offers superior current gain compared to A or B grades. Consider the TO-92 through-hole package for prototyping or applications where surface-mount options are not feasible. Evaluate thermal management needs given the 500 mW power dissipation limit.

Single Bipolar Transistors Part Context

This transistor is part of the widely used BC546/BC547/BC548 family of general-purpose NPN silicon transistors. These devices are standard components in electronic design, offering complementary PNP counterparts in the BC556-BC558 series. The BC546 specifically provides higher voltage ratings than the BC548, making it suitable for slightly more demanding voltage applications within the same gain families.
