1N3823A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3823A-1/TR is a hermetically sealed Zener diode in the DO-13 metal case. It provides a nominal voltage of 3.9 V at a test current of 64 mA. The device features a maximum impedance of 9 Ohms and a maximum reverse leakage current of 50 µA. It supports a maximum Zener current of 238 mA and operates within a temperature range of -65°C to +175°C. The 'TR' suffix indicates tape and reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for high reliability
• Internally solder-bonded design resistant to ESD
• Inherently radiation hard characteristics

Single Zener Diodes Applications

• High-reliability military applications
• Voltage regulation over broad operating currents
• Low voltage reference circuits

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required package configuration, as the TR suffix denotes tape and reel packaging. Confirm RoHS compliance status if lead-free material is specified, noting that standard versions may use tin-lead finishes. Ensure the part number prefix aligns with the necessary screening level for the intended environment.

Single Zener Diodes Selection Notes

Select this component for low-voltage regulation needs requiring tight tolerances and low leakage. The DO-13 metal package offers superior thermal dissipation compared to glass equivalents. Consider the specific screening levels available via JAN prefixes if the application demands rigorous qualification standards beyond standard JEDEC registration.

Single Zener Diodes Part Context

This part belongs to the established 1N3821 through 1N3830A series registered with JEDEC. The series covers a low voltage selection from 3.3 V to 7.5 V in the same hermetically sealed DO-13 package. Higher voltage options are available in the 1N3016 through 1N3051 series using identical mechanical housing.

Single Zener Diodes FAQ

What is the polarity configuration of the DO-13 package?

The cathode is connected to the metal case.

How is the Zener impedance measured?

It is derived when a 60 cycle AC current having an RMS value equal to 10% of the DC Zener current is superimposed on the test current.
