1N5243A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5243A/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 (DO-204AH) package, featuring a nominal voltage of 13 V with ±10% tolerance. It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Offers minimal capacitance characteristics suitable for high-frequency circuits

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the tape-and-reel packaging format as specified in the datasheet. Confirm the 'A' suffix indicates the required ±10% voltage tolerance. Ensure compatibility with the DO-35 package dimensions for your PCB layout requirements.

Single Zener Diodes Selection Notes

Select this component when a 13 V Zener voltage with standard 10% tolerance is needed. The 500 mW power dissipation rating supports moderate current loads. Verify thermal derating requirements if operating near maximum ambient temperatures or in confined spaces.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series provides a wide selection of voltages from 2.4 V to 200 V in the DO-35 glass axial-lead package, serving as a standard solution for low-power voltage regulation needs.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5243A devices in the DO-35 package. Surface mount equivalents are available in the MLL5243 MELF style. Verify pinout and electrical parameters match before substitution.
