1N5383/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5383/TR8 is a silicon Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 150 V with a ±5% tolerance, indicated by the 'B' suffix. The device features a 5.0 W power dissipation rating and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 axial lead case with a TR suffix for tape and reel delivery, it utilizes a void-free transfer molded thermosetting epoxy body.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'TR' suffix to confirm tape and reel packaging rather than cut tape or bulk. Confirm the 'B' suffix indicates the required ±5% voltage tolerance. Ensure the component meets specific military screening requirements if applicable, as standard versions differ from screened prefixes.

Single Zener Diodes Selection Notes

Select this component when a 150 V regulation point is required with moderate precision. Consider the 5 W power rating and thermal resistance characteristics for heat sinking requirements. Verify compatibility with existing PCB layouts due to the T-18 axial lead package dimensions and spacing constraints.

Single Zener Diodes Part Context

This device belongs to the Microsemi 1N5333-5388B series of 5-watt silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5383 variant specifically targets the 150 V segment of this lineup, providing a robust solution for medium-to-high voltage regulation tasks in industrial and commercial electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5383 variants meeting the same electrical specifications. Surface mount equivalents such as SMBJ5383B are available for designs requiring different form factors.
