Procurement Notes
Verify the specific suffix 'G' against the manufacturer's latest documentation to confirm lead-free compliance status. Confirm availability as the component may be subject to lifecycle changes or obsolescence notices. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement specifications.
Selection Notes
Select the 2N5061G when a low-current SCR is required for simple trigger applications. Compare the 400 V rating against the peak line voltage to ensure adequate safety margins. Evaluate the thermal management requirements based on the TO-92 package's power dissipation limits. Consider alternative packages if higher current capacity or surface-mount compatibility is necessary for the target design.
Part Context
The 2N5061G belongs to the standard NPN-style SCR family historically defined by JEDEC numbering. This specific part number represents the onsemi manufacturing variant of the classic 2N5061 device. It serves as a direct replacement for legacy designs requiring a small-signal thyristor. The component is widely recognized in educational and industrial prototyping contexts for basic phase-control experiments.
Replacement Considerations
Direct equivalents include the STMicroelectronics BCR1AM or similar generic 2N5061 variants from other manufacturers. Verify pinout compatibility and exact voltage ratings when substituting. Check for any differences in gate trigger current specifications that might affect circuit performance.
