1N5342CE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5342CE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 6.8 V and a tight tolerance of ±2%. It operates in the -65°C to +150°C range, features a T-18 axial lead package, and includes tape-and-reel packaging for automated assembly.

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 integration
• Withstands high surge stresses and exhibits minimal changes in voltage versus current

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 component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status and ensure the specific suffix matches required tolerance levels. Validate thermal management requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within a 2% tolerance is required at 5 watts. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during continuous operation.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'C' suffix indicates a tighter ±2% voltage tolerance compared to standard B suffix devices, while the 'e3' denotes RoHS compliance.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N5342 variants with matching tolerances (e.g., 1N5342B). Verify that replacement parts meet the same 5W power dissipation and T-18 package specifications.
