Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging or environmental standards. Confirm that the active status aligns with long-term supply requirements. Cross-reference the pinout configuration with the target PCB footprint to prevent installation errors during assembly.

Single Bipolar Transistors Selection Notes

Select this component when driving inductive loads requiring integrated overvoltage protection. The high current gain simplifies base drive circuitry design. Ensure the application voltage does not exceed the 50V collector-emitter rating. Consider the thermal characteristics if continuous high-current operation is anticipated.

Single Bipolar Transistors Part Context

This part belongs to the family of small signal bipolar transistors manufactured by onsemi. It is specifically engineered for general-purpose switching applications where high gain and inductive load protection are necessary. The TO-226 package provides a standard form factor for through-hole mounting in various electronic assemblies.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the NPN type, 1.2A current rating, 50V voltage rating, and integrated Zener diode feature. Verify pinout compatibility and package dimensions before substitution.
