Overview
The Central Semiconductor Corp 1N4694 TR TIN/LEAD is a single axial-lead Zener diode housed in a DO-35 package. It features a nominal Zener voltage of 8.2 V with a tolerance of ±5%. The device supports a maximum power dissipation 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 1 µA and a Zener impedance of 1.4 kΩ at a test current of 250 µA.
Feature Summary
- Provides stable voltage regulation through Zener breakdown mechanism
- Utilizes tin/lead plating for solderability and compatibility
- Designed for through-hole mounting in axial configurations
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection for sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific ordering suffix requirements when requesting tin/lead plated devices, as this may affect availability and compliance status. Confirm that the DO-35 axial package aligns with your PCB footprint constraints. Ensure that the 500 mW power rating meets the thermal management requirements of your specific application environment before finalizing procurement decisions.
Selection Notes
Select this component when a standard 8.2 V Zener voltage is required in an axial leaded package. The DO-35 form factor suits through-hole assembly processes. Consider the 500 mW power dissipation limit and the wide operating temperature range up to 200°C for high-temperature environments. Verify that the 1 µA leakage current specification meets the precision requirements of your circuit design.
Part Context
This part belongs to the 1N46xx series of Zener diodes manufactured by Central Semiconductor. These diodes are commonly used in general-purpose voltage regulation and protection applications. The series offers various voltage options within a standardized axial package format, facilitating easy integration into legacy and modern through-hole designs.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4694 equivalents in DO-35 packages. Ensure that substitute parts match the 8.2 V nominal voltage, 500 mW power rating, and ±5% tolerance. Verify pinout compatibility and thermal performance characteristics before implementation.
