1N4693 TR TIN/LEAD

Overview

The 1N4693 TR TIN/LEAD is a silicon planar Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 7.5 V with a standard tolerance of ±5%. The device is rated for 500 mW power dissipation and utilizes a DO-35 through-hole package. The suffix 'TR' indicates tape and reel packaging, while 'TIN/LEAD' specifies the terminal finish.

Feature Summary

• Silicon planar construction for reliable performance
• Standard Zener voltage tolerance of ±5%
• Through-hole DO-35 package configuration

Applications

• Voltage regulation in low-power circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and plating. The 'TR' designation confirms tape and reel supply, distinct from bulk packaging. Confirm 'TIN/LEAD' finish requirements if lead-free compliance is not mandated. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Selection Notes

Select this component when a 7.5 V reference is required in a DO-35 form factor. Ensure the 500 mW power rating meets the circuit's thermal dissipation needs. Verify that the ±5% voltage tolerance aligns with the application's precision requirements. Confirm compatibility with automated assembly processes due to the tape and reel format.

Part Context

This part belongs to the single Zener diode family from Central Semiconductor. It shares the DO-35 package style with other axial-lead devices in the series. The tin/lead plating option serves applications requiring specific solderability characteristics or legacy manufacturing standards.

Replacement Considerations

Direct substitutes must match the 7.5 V Zener voltage, 500 mW power rating, and DO-35 package. Verify pinout compatibility and electrical tolerances before swapping. Generic equivalents may differ in impedance or leakage current specifications.
