1N5335CE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5335CE3/TR12 is a JEDEC registered silicon 5.0-watt Zener diode in the 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 3.9 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within an ambient temperature range of -65°C to +150°C and features RoHS compliance, denoted by the 'e3' suffix. Packaged in a T-18 axial lead format, it is supplied in tape and reel configuration as specified by the 'TR12' suffix.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR12' suffix to ensure the correct tape and reel packaging. Confirm the 'C' suffix corresponds to the required ±2% voltage tolerance. Check for any prefix identifiers if military screening levels such as JAN or JANTX are required for specific applications.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V Zener voltage with ±2% tolerance is required for high-power applications up to 5 watts. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits. Consider the T-18 package dimensions for PCB layout compatibility and verify that the operating temperature range meets the environmental requirements of the target system.

Single Zener Diodes Part Context

This component belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' designation indicates lead-free construction with matte tin plating, while the 'TR12' suffix specifies the standard EIA-296 tape and reel packaging format used for automated assembly processes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series or SMBG5333B to SMBG5388B series. Verify that the replacement device matches the required voltage, power dissipation, and tolerance specifications.
