1N4764A

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.

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

Applications

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

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.

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.

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.

Replacement Considerations

• 1N4764A (Generic JEDEC equivalent)
• MSP1N4764AURTR (Surface mount MELF equivalent)
