1N5337A/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5337A/TR8 is a silicon 5.0-watt Zener diode belonging to the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 4.7 volts with a standard tolerance of plus or minus 10 percent, indicated by the 'A' suffix. The device utilizes a T-18 axial-lead plastic encapsulated package and operates within an ambient temperature range of -65°C to +150°C. The TR8 suffix designates tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• 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 per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 4.7V reference
• Power supply protection against overvoltage conditions
• Clamping applications for transient voltage suppression

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the presence of the 'TR8' designation indicates tape and reel packaging rather than bulk quantities. Ensure the 'A' suffix corresponds to the necessary plus or minus 10 percent voltage tolerance. Validate compliance requirements regarding lead content and RoHS status based on specific project constraints.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current regulation tasks. Choose the A suffix specifically for applications allowing a wider plus or minus 10 percent voltage tolerance band. Consider the T-18 package dimensions for adequate heat sinking to maintain performance under steady-state power loads.

Single Zener Diodes Part Context

This part belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 to 200 volts. Different suffix letters identify specific voltage tolerances, while prefixes can indicate military equivalent screening levels such as JAN or JANTXV.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. RoHS compliant versions are available by adding the e3 suffix to the base part number.
