1N5363B/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5363B/TR8 is a silicon unidirectional Zener diode with a nominal voltage of 30V and a maximum power dissipation of 5W. It features a ±5% tolerance, an axial T-18 plastic package, and two terminals. The device operates within a temperature range of -65°C to +150°C, has a maximum dynamic impedance of 8Ω, and a maximum reverse current of 0.5μA at 21.6V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and maintains minimal voltage changes versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• General-purpose discrete semiconductor designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR8' against official Microsemi documentation to confirm tape and reel packaging compliance. Ensure the component meets project requirements for leaded construction and standard JEDEC registration rather than military screening levels. Confirm RoHS status as the 'e3' suffix indicates compliance, whereas this part lacks that designation.

Single Zener Diodes Selection Notes

Select this component when a 30V Zener voltage with 5W power handling is required in an axial leaded format. Consider the thermal resistance characteristics and derating curves for proper heat sinking. Verify that the ±5% tolerance aligns with circuit precision needs compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0 watt Zener diodes. The series offers voltages from 3.3V to 200V. The 'B' suffix identifies the standard ±5% voltage tolerance. The 'TR' suffix denotes tape and reel packaging options available for this family.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5363B or SMBG5363B. RoHS compliant versions exist under the 1N5363BE3 designation. Military screening variants utilize MQ, MX, or MV prefixes.
