1N4693 TR PBFREE

Overview

The Central Semiconductor Corp 1N4693 TR PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 7.5 V with a 5% tolerance, tested at 50 μA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. Packaged in the DO-35 axial leaded format, it offers a maximum reverse leakage current of 10 μA and a maximum regulator current of 31.8 mA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Features a 5% voltage tolerance for precise regulation
• Supports high junction temperatures up to +200°C

Applications

• Low-level voltage reference circuits
• Precision voltage regulation
• Low current protection applications

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specific reel packaging configuration required by your assembly line. Confirm that the 'PBFREE' designation aligns with RoHS compliance requirements for your manufacturing process. Ensure the DO-35 package dimensions match your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when circuit designs demand minimal quiescent current consumption alongside stable voltage regulation. The 500 mW power rating allows for moderate current handling in compact axial packages. Consider the 5% tolerance band if tighter precision is not critical, as it provides cost-effective performance for general-purpose low-level stabilization tasks.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes from Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing common electrical characteristics such as 50 μA test currents and 500 mW power dissipation capabilities. These devices are standardized for use in applications prioritizing low leakage and stable performance under varying thermal conditions.

Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes with 7.5 V nominal voltage and 500 mW ratings. Verify that substitute components meet the same 5% tolerance and low leakage specifications to ensure circuit compatibility without redesign.
