Single Zener Diodes Procurement Notes
Verify that the component matches the exact part number 1N4685 BK PBFREE. Confirm RoHS compliance status through official datasheets or manufacturer documentation before procurement. Ensure the ordering suffix PBFREE corresponds to lead-free plating as defined by the manufacturer's standard terms.
Single Zener Diodes Selection Notes
Select this component when circuit design requires stable voltage reference at low currents. Verify that the 500 mW power dissipation rating meets thermal requirements. Check that the 3.6 V nominal voltage aligns with system specifications. Consider the DO-35 package constraints for PCB layout.
Single Zener Diodes Part Context
This device belongs to the 1N4678 through 1N4717 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V with consistent 5% tolerance and 500 mW power rating across all variants in the family.
Single Zener Diodes Replacement Considerations
Substitute parts must match the 3.6 V nominal Zener voltage, 500 mW power rating, and DO-35 package. Verify electrical characteristics such as leakage current and test current compatibility with the original specification.
