BC546A-AP

Single Bipolar Transistors Overview

The BC546A-AP is a small signal NPN silicon transistor manufactured by Micro Commercial Components (MCC). It features a maximum collector current of 0.1 A and a collector-emitter breakdown voltage of 30 V. The device operates within a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 625 mW. It utilizes a TO-92 through-hole package with three leads. The minimum DC current gain (hFE) is specified as 110 at a collector current of 2 mA and a collector-emitter voltage of 5 V.

Single Bipolar Transistors Feature Summary

• NPN silicon construction for general-purpose amplification
• Lead-free finish and RoHS compliant manufacturing
• Epoxy casing meeting UL 94 V-0 flammability rating

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications in low-power electronics
• Signal processing stages requiring moderate gain

Single Bipolar Transistors Procurement Notes

Verify the specific datasheet version from MCC, as specifications may vary between revisions. Confirm that the 'AP' suffix denotes RoHS compliance and lead-free status as per manufacturer standards. Ensure the TO-92 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when a 30V NPN transistor with a minimum hFE of 110 is required. It serves as a direct replacement for standard BC548A devices. Consider the 625mW power limit and TO-92 thermal characteristics for heat dissipation needs in enclosed designs.

Single Bipolar Transistors Part Context

This part belongs to the BC546/BC547/BC548 series of NPN silicon transistors produced by MCC. These components are widely used in consumer electronics and industrial control systems. The BC546A variant specifically offers higher gain than the BC548A but lower voltage tolerance compared to the BC546B/C variants.

Single Bipolar Transistors Replacement Considerations

Verified substitutes include BC548A-AP and BC546B-AP from MCC. Cross-manufacturer equivalents such as ON Semiconductor's BC548A or Vishay's BC546A may be compatible if pinout and electrical ratings align.
