1N5347E3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5347E3/TR8 is a silicon Zener diode with a nominal voltage of 10 V and a maximum power dissipation of 5 W. It features a ±5% tolerance, indicated by the 'B' suffix in its base part number. The device utilizes a T-18 axial leaded plastic package and includes an 'e3' suffix denoting RoHS compliance. It 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 through-hole integration.
• Withstands high surge stresses and exhibits minimal changes in voltage versus current.
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registered series designation and confirm the presence of the e3 suffix to ensure RoHS compliance. Ensure the ordering suffix TR8 corresponds to the required tape and reel packaging format as specified in the manufacturer documentation.

Single Zener Diodes Selection Notes

Select this component when a 5 W power rating and a 10 V nominal breakdown are required. The B suffix indicates a standard ±5% tolerance suitable for general-purpose regulation. Verify thermal management requirements, as the device supports high DC currents only with adequate heat sinking due to its low thermal resistance design.

Single Zener Diodes Part Context

This component belongs to the 1N5333B thru 1N5388B series of silicon 5 Watt Zener Diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters on the part number.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the part numbers.
