Overview
The Central Semiconductor Corp 1N4689 BK TIN/LEAD is a single Zener diode designed for through-hole mounting in the DO-35 package. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA and a test current of 55 mA.
Feature Summary
- Provides stable voltage regulation at a nominal 5.1 V level
- Capable of handling high operating temperatures up to 200°C
- Low reverse leakage current ensures minimal power loss in standby states
Applications
- Voltage reference circuits requiring precise 5.1 V levels
- Overvoltage protection for low-power electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix 'BK TIN/LEAD' to confirm lead-free plating restrictions or tin-lead alloy composition as required by project specifications. Ensure the manufacturer is identified as Central Semiconductor Corp to distinguish from other vendors using similar part numbers. Cross-reference datasheet parameters against design requirements before finalizing procurement orders.
Selection Notes
Select this component when a robust, high-temperature Zener diode is needed for through-hole assembly. The 500 mW power rating suits moderate current applications. Consider the ±5% voltage tolerance for precision requirements. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical.
Part Context
This component belongs to the standard Zener diode family produced by Central Semiconductor. It utilizes the DO-35 axial leaded package, which is common for general-purpose discrete semiconductor devices. The part is distinct from surface-mount variants and higher-power series like the CZ53xx line.
Replacement Considerations
Check for direct equivalents such as the 1N4689 from other manufacturers ensuring identical 5.1 V Zener voltage and 500 mW power rating. Verify pinout compatibility and package dimensions (DO-35) for mechanical fit. Confirm that replacement parts meet the same temperature and leakage current specifications.
