1N4767

Overview

The Microchip Technology 1N4767 is a temperature-compensated Zener reference diode designed for precision voltage regulation. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The device operates in the low current range, typically tested at 0.5 mA or 1.0 mA, and has a maximum DC power dissipation of 500 mW at +50°C. It utilizes metallurgically bonded double plug construction to ensure stability. The component supports an operating temperature range from -65°C to +175°C and is available in the DO-35 axial through-hole package.

Feature Summary

• Temperature compensated design for stable voltage reference performance across wide thermal ranges
• Metallurgically bonded double plug construction for enhanced reliability
• Low current operation optimized for precision regulation applications

Applications

• Precision voltage reference circuits
• Temperature compensated regulation systems
• Low current voltage stabilization

Procurement Notes

Verify RoHS compliance status as the specific 1N4767 variant may be non-compliant depending on the manufacturer revision. Confirm the exact test current (0.5 mA vs 1.0 mA) required for your application against the datasheet specifications. Ensure the DO-35 package dimensions match your PCB layout constraints. Check for any specific military screening prefixes if high-reliability standards are required.

Selection Notes

Select this component when a stable 9.1 V reference is needed in harsh thermal environments. The temperature compensation feature makes it suitable where standard Zeners would drift significantly. Verify that the 500 mW power rating is sufficient for your circuit's thermal conditions. Consider the ±5% tolerance if tighter voltage accuracy is not critical.

Part Context

This part belongs to the 1N4765 through 1N4774A series of temperature-compensated Zener reference diodes manufactured by Microchip Technology. These components are engineered for applications requiring precise voltage references over extended temperature ranges. The series shares common packaging and construction technologies but varies in nominal voltage output.

Replacement Considerations

Direct substitutes within the same Microchip series include 1N4765A, 1N4768A, 1N4769A, and 1N4770A, which share similar construction and temperature compensation characteristics.
