1N4697 TR TIN/LEAD

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.
