1N5388E3/TR12

Overview

The Microsemi Corporation 1N5388E3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 200V and a ±20% 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.

Feature Summary

• Provides voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Flexible axial-lead mounting terminals facilitate installation

Applications

• Voltage regulation circuits
• Surge protection applications
• High maximum DC current operations with adequate heat sinking

Procurement Notes

Verify the specific part number against official Microsemi documentation to confirm RoHS compliance status and manufacturing origin. Ensure that the tape and reel configuration matches your automated assembly requirements. Cross-reference datasheet electrical characteristics with your circuit design parameters before procurement.

Selection Notes

Select this component when a 200V Zener voltage with wide tolerance is required. Consider the 5W power dissipation capability and thermal resistance specifications for proper heat sinking. Verify if military screening prefixes are necessary for your specific application environment.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zeners. The series provides a selection from 3.3 to 200 volts with various tolerances identified by specific suffix letters on the part number.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B.
