BC548C A1G

Single Bipolar Transistors Overview

The BC548C A1G is an NPN silicon planar epitaxial bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a collector-emitter breakdown voltage of 30V and a maximum continuous collector current of 100mA. The device provides a minimum DC current gain (hFE) of 200 when tested at 2mA collector current and 5V collector-emitter voltage. It is housed in a TO-92-3 through-hole package with a maximum power dissipation of 500mW. The component operates within a junction temperature range of -65°C to 150°C.

Single Bipolar Transistors Feature Summary

• NPN silicon planar epitaxial construction for reliable small-signal amplification
• High DC current gain classification ensuring consistent performance in low-current applications
• Through-hole TO-92-3 packaging suitable for standard prototyping and PCB assembly

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Switching applications requiring low base drive currents
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A1G' against the manufacturer's official datasheet to confirm pinout orientation and marking codes, as variations exist within the BC548 family. Confirm RoHS compliance status directly from the latest production documentation. Check for end-of-life notifications or discontinuance alerts, as availability may be restricted. Ensure the supplier provides traceable origin data matching Taiwan Semiconductor Corporation specifications.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-voltage, low-current operations. The 'C' suffix indicates a tighter gain bin compared to 'A' or 'B' variants, offering higher hFE consistency. Verify that the 30V collector-emitter rating meets the circuit's maximum voltage requirements. Consider thermal management if operating near the 500mW power limit in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the BC5xx series of general-purpose NPN transistors produced by Taiwan Semiconductor. The BC548 variant specifically targets applications needing moderate voltage handling and high current gain. The 'A1G' suffix typically denotes the specific tape-and-reel or bulk packaging configuration and lead finish compliant with environmental directives, distinct from the bare device designation.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other manufacturers' BC548C devices in TO-92 packages. Verify pinout compatibility and electrical parameter equivalence before substitution.
