Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A1G' against official Taiwan Semiconductor documentation to confirm exact binning and packaging details. Confirm end-of-life status with the manufacturer, as discontinuation notices may affect long-term availability. Ensure the procurement channel provides valid traceability for the component origin.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 45V rating and 100mA capacity is required. The TO-92 package suits prototyping and low-volume production. Verify that the hFE binning meets circuit requirements, as gain varies across the series. Consider thermal management for the 500mW dissipation limit in enclosed designs.

Single Bipolar Transistors Part Context

This part belongs to the BC5xx series of general-purpose NPN transistors. It shares pinouts and basic electrical characteristics with other variants in the family, differing primarily in current gain bins. The TO-92 form factor is widely used in consumer electronics and industrial control boards.
