1N4764A

Single Zener Diodes Overview

The SMC Diode Solutions 1N4764A is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 100V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1W at 25°C. It utilizes a DO-41 glass axial leaded package, which provides hermetic sealing and high reliability. The component supports an operating junction temperature up to 200°C and a storage temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass package construction for environmental protection
• Planar die technology ensuring stable voltage regulation characteristics
• High thermal stability suitable for demanding operating environments

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement instrumentation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N4764A is a JEDEC registered part number produced by multiple vendors. Confirm that the supplier provides documentation confirming the ±5% tolerance and 1W power rating. Ensure the package matches the required DO-41 form factor for your assembly process. Check for RoHS compliance status if required by your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a precise 100V regulation point is required with moderate current capabilities. The DO-41 package is appropriate for through-hole mounting on standard PCBs. Consider the thermal derating requirements if the ambient temperature exceeds standard conditions. The glass passivation offers superior leakage current performance compared to plastic encapsulated alternatives in harsh environments.

Single Zener Diodes Part Context

This component belongs to the widely recognized 1N47xx series of 1-watt Zener diodes. These devices are standardized across the semiconductor industry, allowing for interchangeability between manufacturers like Microsemi, onsemi, and others. The 'A' suffix specifically denotes the tighter ±5% voltage tolerance band compared to the standard ±10% version.
