BC547CNMBU

Single Bipolar Transistors Overview

The BC547CNMBU is a single NPN epitaxial silicon transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. It features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 100 mA. The device operates within a junction temperature range up to 150°C and dissipates a maximum power of 500 mW. Key electrical characteristics include a DC current gain (hFE) ranging from 110 to 800 at specific test conditions, a transition frequency of 300 MHz, and a collector cutoff current of 15 nA. It is housed in a TO-92-3 through-hole package.

Single Bipolar Transistors Procurement Notes

Verify the exact suffix CNMBU against the manufacturer's official datasheet to confirm pinout orientation and specific hFE binning requirements. Ensure the procurement channel provides valid traceability documentation for this specific through-hole component variant. Confirm that the TO-92-3 package dimensions match the target PCB footprint constraints before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 45V breakdown and 100mA current capacity is required for low-power analog or digital switching tasks. Consider the wide hFE range (110-800) if precise biasing is not critical. Compare against complementary PNP devices like the BC557 series for push-pull configurations. Evaluate thermal management needs given the 500mW power dissipation limit in the TO-92 package.

Single Bipolar Transistors Part Context

This part belongs to the BC546-BC550 series of NPN transistors, which are widely used in consumer electronics and industrial control systems. The BC547 variant specifically offers a 45V rating, distinguishing it from lower-voltage siblings like the BC548. It serves as a fundamental discrete semiconductor component for basic circuit building blocks.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include MMBT100 and 2N5232A PBFREE. Verify compatibility regarding pinout alignment and electrical parameter margins before substitution.
