1N5343A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5343A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 7.5 V and a standard tolerance of ±10%, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The '/TR12' suffix denotes tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for secure installation
• Withstands high surge stresses during operation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B, requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required voltage tolerance and packaging format. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Check manufacturer documentation for any product change notifications or discontinuance alerts associated with this component series before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and a 7.5 V reference are required. Ensure adequate heat sinking is provided to maintain performance at maximum DC currents. Consider the ±10% tolerance if tighter precision is not critical for the application design.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V in a robust plastic encapsulated axial-lead package designed for high-power applications.

Single Zener Diodes Replacement Considerations

Consult official datasheets for direct equivalents within the same series. Verify mechanical dimensions and electrical characteristics match before substitution.
