1N5342E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5342E3/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 6.8 V and a standard tolerance of ±5%. The device features an axial-lead T-18 package, operates within a temperature range of -65°C to +150°C, and includes RoHS compliance indicated by the e3 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 installation
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm availability and specifications. Check for any recent product change notices or obsolescence announcements directly from Microchip Technology. Ensure that the ordering suffixes match the required packaging and environmental compliance standards for your specific application requirements.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and a 6.8 V Zener voltage are required. Consider the T-18 axial lead package for through-hole mounting needs. Evaluate thermal resistance characteristics and derating curves if operation at elevated ambient temperatures or high DC currents is anticipated.

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 3.3V to 200V with various tolerance options. The 1N5342E3 variant specifically denotes the 6.8V version with RoHS compliant plating.

Single Zener Diodes Replacement Considerations

Consult official datasheets for equivalent parts within the same series or comparable 5W Zener diodes from other manufacturers. Verify pinout compatibility and electrical parameters such as dynamic impedance and reverse leakage current before substitution.
