1N4895

Single Zener Diodes Overview

The Microsemi Corporation 1N4895 is a silicon voltage reference diode housed in a DO-35 (DO-204AA) axial glass package. It functions as a temperature-compensated Zener diode with a nominal breakdown voltage of 6.35 V. The component features two terminals and an isolated case connection, designed for applications requiring stable voltage references across varying thermal conditions.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature-compensated power supply regulation
• Calibration standards requiring stable DC voltage

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as New Jersey Semiconductor also produces this part number. Confirm RoHS compliance status, as some listings indicate non-compliance. Ensure the package matches the required DO-35 form factor. Check for specific suffix variations that may denote tolerance or testing levels. Validate datasheet version against the supplier's documentation to ensure accurate electrical specifications.

Single Zener Diodes Selection Notes

Select this component when a fixed 6.35 V reference with low temperature drift is required. Compare its compensation curve against standard Zener diodes if high precision is needed. Consider the axial leaded package constraints for PCB layout. Verify that the power dissipation capabilities meet the circuit's thermal requirements under continuous operation.

Single Zener Diodes Part Context

This device belongs to the family of ultra-stable temperature-compensated Zener reference diodes. These components are engineered to minimize voltage variation over temperature ranges where standard Zeners exhibit significant drift. They serve as critical reference elements in analog signal processing and measurement instrumentation.

Single Zener Diodes Replacement Considerations

The 1N4895A is a documented variant within the same series. Verify pinout compatibility and exact voltage tolerance before substitution. Ensure the replacement maintains the same axial glass package dimensions.
