1N5335AE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5335AE3/TR8 is a silicon unidirectional Zener diode with a nominal voltage of 3.9 V and a tolerance of ±10%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes a tape and reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses with minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for secure installation

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure compliance with RoHS requirements and packaging preferences. Confirm that the tape and reel format aligns with automated assembly equipment specifications. Cross-reference the manufacturer's latest documentation to validate current production status and availability constraints before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V reference with ±10% tolerance is required for high-power applications up to 5 watts. Ensure adequate heat sinking is provided to maintain operation within the specified thermal limits. Verify that the axial lead form factor fits the designated PCB layout and mechanical constraints of the target design.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters. The e3 suffix indicates RoHS compliance, while the TR suffix denotes tape and reel packaging.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5W Zener diodes with 3.9V nominal voltage and ±10% tolerance in T-18 packages. Verify electrical parameters and physical dimensions match before substitution.
