1N4688 TR TIN/LEAD is listed in the Single Zener Diodes range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is 4.7V 500MW TH DIODE-ZENER SINGLE. Review the specifications below when checking this part for your BOM.
The 1N4688 TR TIN/LEAD is a single Zener diode manufactured by Central Semiconductor Corp, designed for through-hole mounting in DO-35-2 packages. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5% and a power dissipation rating of 500 mW. The device operates within a temperature range of -65°C to +200°C and exhibits a maximum reverse leakage current of 10 µA at a reverse voltage of 3 V. It is supplied in tape and reel packaging.
Verify the specific ordering suffix 'TIN/LEAD' to ensure compliance with material requirements. Confirm that the 'TR' designation indicates tape and reel packaging rather than bulk supply. Cross-reference the manufacturer part number with distributor codes to ensure accurate component identification during procurement.
Select this component when a 4.7 V Zener reference is required in high-temperature environments. The DO-35-2 form factor suits standard through-hole assembly processes. Ensure the 500 mW power rating meets the circuit's thermal dissipation needs under all operating conditions.
This part belongs to the 1N4688 series of Zener diodes from Central Semiconductor. The series offers various voltage options within the DO-35 package family. The tin/lead variant addresses specific regulatory or legacy manufacturing requirements distinct from lead-free alternatives.
Substitute parts must match the 4.7 V Zener voltage, 500 mW power rating, and DO-35 package outline. Verify compatibility with existing PCB footprints and thermal management strategies before implementation.
