Overview
The Central Semiconductor Corp 1N4697 TR TIN/LEAD is a silicon Zener diode housed in a DO-35 axial leaded package. It provides a nominal Zener voltage of 10V with a tolerance of 5%. The device is rated for a maximum steady-state power dissipation of 500mW at a lead temperature of 75°C, with derating required above this threshold. It operates within a junction and storage temperature range of -65°C to +200°C. The component utilizes double slug type construction with metallurgically bonded features.
Feature Summary
- Metallurgically bonded construction for enhanced reliability
- Hermetically sealed glass encapsulation
- High ESD protection capability per Human Body Model
Applications
- Voltage regulation in high-reliability circuits
- Overvoltage protection for sensitive components
- Reference voltage generation in precision instrumentation
Procurement Notes
Verify the specific suffix 'TR' against official datasheets to confirm tape-and-reel packaging status versus bulk availability. Ensure the tin/lead plating specification aligns with project requirements, noting potential restrictions in RoHS-compliant environments. Cross-reference the manufacturer's current production status and lead times directly with Central Semiconductor or authorized distributors prior to procurement planning.
Selection Notes
Select this component when a 10V Zener reference is required in a DO-35 package with hermetic sealing capabilities. The 500mW power rating suits low-current regulation tasks. Consider the wide operating temperature range up to 200°C for harsh environment applications. Verify that the 5% voltage tolerance meets circuit accuracy specifications before finalizing the design.
Part Context
This part belongs to the 1N4697 series of Zener voltage regulators licensed by ON Semiconductor. The series covers a broad voltage range from 1.8V to 43V in the DO-35 package. These diodes are designed for applications requiring stable voltage references and robust performance under extreme thermal conditions.
Replacement Considerations
Check for direct equivalents such as the 1N4697RA2 or 1N4697D-1 from other manufacturers like Tak Cheong or Microsemi. Ensure pinout compatibility and verify that alternative packages meet the same hermetic sealing and power dissipation standards.
