1N5342CE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5342CE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial DO-41 package with RoHS-compliant tin plating. It provides voltage regulation at a nominal Zener voltage of 6.8V with a tight ±2% tolerance. Key electrical parameters include a maximum dynamic impedance of 1.0 ohms and a maximum reverse leakage current of 10 µA. The device withstands a maximum surge current of 49A and operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole integration
• Withstands high surge stresses while maintaining minimal changes in voltage versus current
• Moisture classification Level 1 requiring no dry pack storage

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 ordering suffix 'e3' confirms RoHS compliance and 'TR13' indicates tape-and-reel packaging. Confirm the specific 'C' suffix denotes the required ±2% voltage tolerance. Ensure the component matches the original manufacturer's specifications for the 1N5342 designation before procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.8V reference with high precision (±2%) is required. The 5W power rating supports high-current applications provided adequate heat sinking is implemented. Verify thermal resistance requirements against the application's ambient temperature constraints.

Single Zener Diodes Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5342 or SMBG5342. Other manufacturers may offer direct replacements within the 1N5342 specification; verify pinout and thermal characteristics.
