Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm the exact gain grouping and environmental compliance status. Confirm that the TO-92-3 through-hole package matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the system's thermal constraints before finalizing component selection.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN bipolar junction transistor is required for moderate current handling up to 800 mA. The 45 V collector-emitter voltage rating suits low-voltage logic and analog interfaces. Consider the 260 MHz transition frequency for applications requiring faster signal response than basic audio frequencies. Verify pinout compatibility with existing circuit designs during the integration phase.
