Single Zener Diodes Procurement Notes

Verify the specific plating configuration upon ordering, as the absence of a suffix indicates supply of either lead-free or tin/lead plated product depending on availability. Confirm the required packaging format, such as bulk or tape and reel, directly with the manufacturer or distributor to ensure compatibility with assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 16 V reference is required in a compact surface-mount form factor. Ensure the design accommodates the 1.0 W power dissipation limit and verify that the MELF package dimensions fit the available PCB space. Consider the ±5% tolerance inherent to the 'A' suffix for precision requirements.

Single Zener Diodes Part Context

This part belongs to the CLL4728A through CLL4764A series of 1 Watt Silicon Zener Diodes. The series covers a voltage range from 3.3 Volts to 100 Volts, offering various options for different regulation needs while maintaining consistent physical dimensions and thermal characteristics across the lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 16 V Zener diodes in MELF packages with equivalent 1 W power ratings and similar impedance specifications. Verify pinout orientation and thermal resistance parameters before substitution.
