Single Bipolar Transistors Procurement Notes

Verify the exact datasheet specifications directly from onsemi or authorized distributors before procurement. Confirm that the FLP through-hole package aligns with your PCB footprint requirements. Ensure that thermal management solutions are adequate for the 1.5W power dissipation limit in your specific application environment to maintain reliability.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high-frequency operation up to 180MHz combined with significant current drive capabilities. The 100V rating makes it suitable for medium-voltage applications. Consider the physical size of the FLP package during layout planning. Evaluate thermal constraints carefully, as the 1.5W dissipation limit requires appropriate heat sinking or board copper area utilization.

Single Bipolar Transistors Part Context

This part belongs to the family of single NPN bipolar transistors offered by onsemi. It is specifically engineered for radio frequency and wideband amplification tasks where stability and linearity at VHF/UHF frequencies are critical. The FLP package provides a standardized mounting solution for industrial and commercial electronic designs.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists from onsemi for verified substitutes. Ensure any replacement maintains the 100V/4A ratings and 180MHz frequency characteristic. Verify package compatibility if substituting with similar NPN BJTs.
