1N4765A

Overview

The Microchip Technology 1N4765A is a temperature-compensated Zener reference diode with a nominal voltage of 9.1 V and a tolerance of ±5%. It features a maximum DC power dissipation of 500 mW at +50°C, with a derating factor of 4 mW/°C above this threshold. The device operates within an extended temperature range from -65°C to +175°C and utilizes a DO-35 axial through-hole package. Maximum reverse leakage current is specified as 10 µA at 25°C and 6 Vdc.

Feature Summary

• Temperature compensated design for stable reference performance
• Metallurgically bonded double plug construction
• Extended operating temperature range suitable for harsh environments

Applications

• Precision voltage reference circuits
• Temperature compensated regulation systems
• Low current range applications requiring stable biasing

Procurement Notes

Verify RoHS compliance status prior to procurement, as specific variants may not meet current environmental directives. Confirm the exact suffix designation matches project requirements, as packaging or material differences can exist between manufacturing lots. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a stable 9.1 V reference is required in low-power applications. The DO-35 package limits thermal handling compared to higher power variants. Verify that the system's ambient temperature remains within the specified operational limits to maintain accuracy without excessive derating.

Part Context

This part belongs to the 1N4765 through 1N4774A series of Zener diodes manufactured by Microchip Technology. These components are designed specifically for applications requiring precise voltage regulation and stability over varying temperatures. The series shares common construction techniques optimized for reliability in critical electronic systems.

Replacement Considerations

Direct substitutes include other 1N4765A variants from different manufacturers, provided they match the 9.1 V nominal voltage, ±5% tolerance, and DO-35 package dimensions. Verify thermal characteristics and leakage current specifications to ensure functional equivalence.
