1N4775A

Overview

The Microchip Technology 1N4775A is a temperature-compensated Zener diode housed in the DO-204AH (DO-35) axial through-hole package. It provides a standard reference voltage of 8.5 V with a tolerance of ±5%. The device features internal metallurgical bonds and is designed for applications requiring stable voltage regulation across varying thermal conditions.

Feature Summary

• Temperature compensated design for stable reference voltage performance
• Internal metallurgical bonds for enhanced reliability
• JEDEC registered series compliance

Applications

• Precision voltage reference circuits
• Temperature-stable regulator designs
• Industrial control systems requiring reliable voltage standards

Procurement Notes

Verify the specific suffix requirements, as variants such as 1N4775A-1 exist with different power ratings. Confirm RoHS status and screening options against project specifications before ordering. Ensure the DO-35 package footprint matches the PCB layout constraints.

Selection Notes

Select this component when a stable 8.5 V reference is required under fluctuating temperatures. Compare power dissipation limits against thermal management capabilities. Verify that the axial leaded format suits the assembly process and mechanical stress requirements of the target application.

Part Context

This part belongs to the JEDEC registered 1N4775 through 1N4784A series manufactured by Microchip Technology. The series is characterized by its temperature compensation features, distinguishing it from standard Zener diodes used in basic voltage clamping or regulation tasks.

Replacement Considerations

Check for compatible substitutes within the same JEDEC series. Variants like 1N4775A-1 may offer different power handling but share the same voltage specification. Ensure pinout and package dimensions are identical for direct replacement.
