1N5232A (DO-35)TR

Single Zener Diodes Overview

The Microsemi 1N5232A (DO-35)TR is a Zener diode with a nominal voltage of 5.6 V and a 10% tolerance, housed in a hermetically sealed glass DO-35 axial package. It dissipates 0.48 W at 25°C ambient or 0.5 W at 50°C lead temperature. The device operates from -65°C to +175°C, features a maximum reverse current of 11 µA at 3 V, and has a dynamic impedance of 5.0 Ω at 0.25 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-35 package for environmental protection
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics
• Flexible axial-lead mounting terminals

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Military screening applications via prefix identifiers
• General purpose voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the suffix 'TR' indicates tape and reel packaging per EIA-296 standards. Confirm the 'A' suffix denotes the standard 10% voltage tolerance. Ensure the component matches the JEDEC registered 1N5232 type specifications for electrical parameters including impedance and leakage current limits.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V Zener reference with 10% tolerance is required in a hermetically sealed glass package. Consider the -1 suffix if internal bonds are needed, or prefixes like MQ/MX for military screening levels. Verify thermal derating requirements against the 0.5 W power dissipation limit at elevated temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series provides voltages from 2.4 to 200 volts with various tolerance options identified by suffix letters. These devices are JEDEC registered and available in surface mount equivalents or DO-7 packages.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5232B for 5% tolerance or 1N5232C/D for tighter tolerances. Surface mount equivalents are available as MLL5232 in the DO-213AA MELF style package.
