Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as listings may reference both onsemi and Sanyo Denki designations. Confirm that the SC-59-3 package matches your board layout requirements. Ensure the 15V voltage rating and 50mA current limits align with your circuit's operational parameters before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when a small-signal NPN transistor with moderate power handling and high-frequency response is required. The 3GHz fT makes it suitable for applications exceeding standard audio frequencies but below ultra-high microwave bands. Consider the 200mW dissipation limit when designing heat dissipation strategies for dense PCB layouts.
