1N5334A/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5334A/TR12 is a silicon unidirectional Zener diode with a nominal voltage of 3.6 V and a power dissipation rating of 5 W at 25°C. It features an axial-lead T-18 plastic package and offers a standard voltage tolerance of ±10%, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and includes a TR suffix denoting tape and reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for secure 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
• High DC current operations with adequate heat sinking

Single Zener Diodes Procurement Notes

Verify the specific part number against official Microsemi documentation to confirm the A suffix denotes ±10% tolerance and TR indicates tape and reel packaging. Ensure compatibility with required thermal management strategies, as steady-state power dissipation depends on lead length or PCB copper pad specifications. Confirm moisture classification Level 1 requirements do not necessitate dry pack storage.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V Zener reference with 5 W power handling is required. The T-18 axial package supports high maximum DC currents if properly heat sunk. Consider the ±10% tolerance suitable for general regulation tasks. Verify that the operating environment stays within the specified -65°C to +150°C range and that surge current capabilities meet circuit demands.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333 through 1N5388B series of silicon 5 Watt Zener diodes. The series provides voltage regulation from 3.3 V to 200 V. The 1N5334 variant specifically targets the 3.6 V regulation point. The series utilizes void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 ratings.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military screening options exist with MQ, MX, or MV prefixes for JAN, JANTX, and JANTXV levels respectively.
