Single Zener Diodes Procurement Notes

Verify the exact part number including the 'BK' suffix and 'PBFREE' designation to ensure correct lead-free specifications. Confirm package type and tolerance requirements against design needs. Purchase only through authorized channels to guarantee authenticity and traceability. Check datasheet for thermal derating curves if operating near maximum power limits.

Single Zener Diodes Selection Notes

Select this component when a low-power, surface-mount Zener diode with a 3.9V breakdown voltage is required. Ensure the application current does not exceed the 5.0mA test current significantly without considering self-heating effects. Verify that the 250mW power rating is sufficient for the specific circuit conditions and ambient temperature.

Single Zener Diodes Part Context

This component belongs to the CMOZ series of Zener diodes from Central Semiconductor. The series offers various voltage options ranging from low levels up to higher voltages, catering to diverse discrete semiconductor needs. Central Semiconductor specializes in standard and custom discrete devices, providing both surface-mount and through-hole options.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 3.9V Zener voltage, 250mW (or higher) power rating, and compatible surface-mount package. Verify impedance and leakage current specifications are within acceptable limits for the specific application. Cross-reference with other manufacturers offering equivalent SMD Zener diodes.
