1N5335B/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5335B/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 3.9V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, features a T-18 axial lead package, and includes a TR suffix for tape and reel packaging.

Single Zener Diodes Feature Summary

• JEDEC registered series providing broad voltage regulation across operating current and temperature ranges
• Flexible axial-lead mounting terminals designed for high maximum DC currents with adequate heat sinking
• Moisture classification Level 1 requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Surge stress protection applications

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the presence of the TR suffix for tape and reel packaging. Ensure compatibility with required thermal management strategies due to the 5-watt power dissipation rating. Confirm RoHS compliance status if environmental regulations apply to the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 3.9V regulation point is required at up to 5 watts of power dissipation. The T-18 package supports through-hole mounting. Consider the thermal resistance characteristics and derating curves for high-current applications to ensure reliable operation within the specified temperature limits.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners. The series offers a wide selection from 3.3 to 200 volts with various tolerances identified by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding environments.

Single Zener Diodes Replacement Considerations

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