Single Zener Diodes Procurement Notes

Verify the specific ordering suffix required for your application. The datasheet indicates that adding 'PBFREE' specifies lead-free plating, while 'TIN/LEAD' specifies tin/lead plating. Ensure the requested suffix matches the exact component variant needed for compliance or soldering requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference with minimal noise is required. Consider the 200 Ω impedance and 250 mW power rating for thermal management. Verify that the operating environment stays within the specified -65°C to +200°C junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N4099 series, which covers Zener voltages from 6.8 V to 100 V. All devices in this series share similar low-noise design characteristics and are housed in the DO-35 case. The series is intended for precision analog applications requiring stable voltage references.

Single Zener Diodes Replacement Considerations

Cross-referencing requires matching the 6.8 V nominal voltage, 250 mW power rating, and DO-35 package. Verify that substitute components meet the same low noise density and impedance specifications to ensure circuit performance remains unchanged.
