1N5363/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5363/TR12 is a silicon Zener diode with a nominal voltage of 30V and a maximum power dissipation of 5.0 watts at 25°C. It utilizes the T-18 axial lead package and features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards. The device operates within a temperature range of -65°C to +150°C, has a thermal resistance of 25°C/W junction-to-lead, and includes a tape and reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• High maximum DC current operations with adequate heat sinking

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tolerance and packaging configuration. Confirm RoHS compliance status if environmental regulations apply, as standard versions may contain lead. Ensure the supplier provides documentation confirming the JEDEC registration and specific screening levels if military equivalents are required.

Single Zener Diodes Selection Notes

Select this component when a 30V Zener voltage with 5-watt power handling is necessary. Consider the ±5% tolerance associated with the B suffix for standard applications. Evaluate thermal management requirements based on the specified junction-to-lead thermal resistance and derating curves for ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different tolerances are identified by specific suffix letters, such as A for ±10%, B for ±5%, C for ±2%, and D for ±1%. The TR suffix indicates availability in tape and reel packaging.
