1N4699/TR

Single Zener Diodes Overview

The Microchip Technology 1N4699/TR is a Zener diode voltage regulator designed for through-hole mounting in the DO-35 axial package. It provides a nominal Zener voltage of 12 V with a power dissipation rating of 500 mW. The device features a voltage tolerance of 5% and operates within a temperature range of -65°C to +175°C junction temperature. It is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 12 V level
• Operates reliably across an extended industrial temperature range up to 175°C
• Utilizes a glass passivated junction for durability

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist between bulk and tape-and-reel formats. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates mixed compliance records for this part family. Ensure the ordering code matches the required packaging format for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a standard 12 V regulation point is required in a compact axial leaded form factor. The 500 mW power rating suits low-current applications where thermal management is straightforward. Verify that the 5% tolerance meets the circuit requirements before finalizing the design.

Single Zener Diodes Part Context

This component belongs to the standard 1N46xx series of Zener diodes manufactured by Microchip Technology. These devices are widely used in discrete semiconductor applications for basic voltage control. The 1N4699 variant specifically targets the 12 V segment of this established product line.

Single Zener Diodes Replacement Considerations

Consult official substitution guides for compatible equivalents. Generic replacements must match the 12 V Zener voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
