1N4698 TR PBFREE

Overview

The 1N4698 TR PBFREE is a silicon unidirectional Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 11V with a tolerance of ±5% and a maximum power dissipation of 0.5W. The device utilizes a DO-35 axial through-hole package with two pins. Key electrical characteristics include a maximum operating temperature of 175°C and an isolated case connection. The component is classified under discrete semiconductor products within the diodes category.

Feature Summary

• Provides stable voltage regulation at a nominal 11V level
• Constructed from silicon material for reliable performance
• Designed for low-level Zener applications

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance in some records. Confirm the specific suffix 'TR PBFREE' matches the required reel packaging format, as standard 1N4698 may differ. Ensure the DO-35 package orientation aligns with board layout requirements. Cross-reference the manufacturer's current datasheet to confirm active production status and exact electrical tolerances before finalizing procurement specifications.

Selection Notes

Select this component when a 11V Zener voltage with 0.5W power rating is required in a through-hole configuration. The DO-35 package offers robust mechanical stability for axial mounting. Consider the 175°C maximum junction temperature for high-thermal environments. Verify that the ±5% tolerance meets the circuit's precision requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the standard 1N46xx series of Zener diodes produced by Central Semiconductor. The series covers various voltage ratings within the low-power range. The 1N4698 specifically targets the 11V segment, providing a standardized solution for general-purpose voltage regulation tasks in discrete semiconductor designs.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4698 variants in DO-35 packages. Verify pinout compatibility and thermal characteristics when replacing. Alternative parts must maintain the 11V nominal voltage and 0.5W power dissipation limits to ensure circuit functionality remains unchanged.
