Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A' against the official onsemi datasheet to confirm binning or packaging specifications. Ensure the ordering part number matches the required hFE range and tape-and-reel configuration. Cross-reference with authorized distributors to validate authenticity and compliance with RoHS standards before procurement.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor with low noise is required for small-signal applications. Compare the 65 V VCEO rating against circuit requirements. Consider the TO-92 package constraints for thermal management and board space. Verify that the 100 mA current limit meets the load demands of the intended design.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN silicon transistors. It serves as a complement to the PNP BC556 series. The family is widely used in consumer electronics and industrial control systems for basic signal conditioning and switching tasks due to its reliability and standard pinout compatibility.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC546BTA from onsemi and equivalent parts from Fairchild Semiconductor such as BC546BTAR. Verify pinout compatibility and ensure electrical parameters like VCEO and IC meet or exceed original requirements.
