Single Bipolar Transistors Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official onsemi documentation. Ensure the TO-126ML package variant matches the required lead configuration. Confirm that the specific lot date code aligns with project requirements. Request test reports if high-reliability standards are mandated for the application environment.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN BJT with moderate power handling is required. The 50 V rating suits low-voltage systems, while the 2.5 A current capacity supports substantial load driving. The 140 MHz transition frequency allows for effective operation in standard audio or intermediate-frequency applications. Consider the through-hole mounting requirement of the TO-126ML package during PCB layout design.
