BC546C-AP

Single Bipolar Transistors Overview

The BC546C-AP is an NPN silicon epitaxial planar transistor manufactured by Micro Commercial Components (MCC). It features a maximum collector-emitter voltage of 65V and a continuous collector current of 100mA. The device has a maximum power dissipation of 625mW at 25°C ambient temperature. It utilizes a TO-92 plastic package with three leads. The component operates within a junction temperature range of -55°C to +150°C. The 'C' suffix indicates a high DC current gain bin, typically starting at a minimum hFE of 320 under specified test conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific datasheet revision from MCC to confirm the exact hFE binning for the C-grade variant, as gain ranges can vary between manufacturing lots. Confirm RoHS compliance status directly with the supplier, as older stock may differ. Ensure the TO-92 package dimensions match your PCB footprint requirements. Check for any recent product change notifications that might affect pinout or material composition.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for voltage amplification. The BC546C-AP offers higher current gain than A or B grade variants, making it suitable for sensitive signal paths. Consider the 65V breakdown voltage for moderate voltage swings. Compare against BC547 or BC548 if different voltage ratings are needed. Ensure the thermal management supports the 625mW dissipation limit in the intended enclosure.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN silicon transistors produced by Micro Commercial Components. The series is widely used in consumer electronics and industrial control systems. The BC546C-AP specifically denotes the high-gain version of the standard BC546 device. It is often paired with its PNP complement, the BC556 series, in complementary symmetry circuits. The AP suffix typically indicates RoHS compliance and halogen-free materials.
