Procurement Notes
Verify that the component matches the exact part number 1N4689 BK PBFREE. Confirm the manufacturer is Central Semiconductor Corp. Ensure the datasheet specifications align with your design requirements, specifically the 500mW power rating and 5% tolerance. Check for RoHS compliance status as indicated by the PBFREE suffix.
Selection Notes
Select this component when a stable 5.1V reference is needed with minimal quiescent current draw. The DO-35 package is suitable for through-hole mounting. Consider the maximum reverse leakage current and voltage change characteristics if high precision is required under varying load conditions.
Part Context
This component belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes from Central Semiconductor. The series covers a voltage range from 1.8V to 43V, all sharing similar electrical characteristics such as 500mW power dissipation and 5% tolerance. The 1N4689 specifically provides a 5.1V nominal output.
Replacement Considerations
Other manufacturers producing standard 1N4689 Zener diodes in the DO-35 package may serve as functional replacements. Verify that any substitute meets the 500mW power rating, 5% tolerance, and operating temperature range specified by Central Semiconductor.
