BC547BNMBU

Single Bipolar Transistors Overview

The BC547BNMBU is an NPN epitaxial silicon bipolar junction transistor manufactured by onsemi. It features a TO-92-3 (TO-226AA) through-hole package with kinked leads. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V. Key electrical characteristics include a minimum DC current gain (hFE) of 200 at 2 mA, a collector-base voltage of 50 V, and an emitter-base voltage of 6 V. Power dissipation is rated at 500 mW, with a maximum operating temperature of +150°C.

• Small-signal amplification stages
• Low-frequency signal processing

Single Bipolar Transistors Procurement Notes

Verify the specific suffix BNMBU against the official onsemi datasheet to confirm pinout orientation and lead configuration. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the supplier offers genuine onsemi products to avoid counterfeit components. Check for any specific handling requirements related to the TO-92 package during assembly.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with moderate voltage ratings and high current gain is required. The TO-92 package is ideal for prototyping and low-volume production where through-hole technology is preferred. Consider the 45V rating and 100mA limit for circuit design constraints. Compare hFE bins if precise gain matching is necessary for the application.

Single Bipolar Transistors Part Context

This part belongs to the BC547 series of NPN transistors from onsemi. The series is widely used in consumer electronics and industrial control systems. The BC547 family offers complementary PNP counterparts, such as the BC557, facilitating push-pull amplifier designs. The BC547BNMBU variant specifically denotes the TO-92-3 package configuration.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547BTA, BC547BBU, and BC547CTA from onsemi, provided they match the required hFE bin and package type. Other manufacturers' equivalents like 2N3904 may be considered if voltage and current ratings are sufficient, though pinouts and gain characteristics may differ.
