1N5388AE3/TR12

Overview

The Microsemi Corporation 1N5388AE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 200V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, features an axial-lead T-18 package, and includes RoHS compliance indicated by the e3 suffix.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features minimal changes in voltage versus current as specified by voltage regulation

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Procurement Notes

Verify that the component matches the exact JEDEC registered part number 1N5388AE3/TR12. Confirm the presence of the 'e3' suffix for lead-free compliance and the 'TR12' suffix for tape and reel packaging. Ensure the manufacturer is identified as Microsemi Corporation or its authorized successor entity.

Selection Notes

Select this component when a 200V Zener voltage with ±10% tolerance is required. The 5W power dissipation rating necessitates adequate heat sinking for continuous operation at maximum currents. Verify that the T-18 axial-lead package fits the intended PCB layout constraints.

Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon 5-watt Zener diodes. The series provides a wide selection of voltages from 3.3V to 200V, utilizing specific suffix letters to denote different voltage tolerances such as A for ±10% and B for ±5%.

Replacement Considerations

Equivalent parts include 1N5388A without the e3/TR12 suffixes if non-RoHS or loose-packaged variants are acceptable. Surface mount equivalents like SMBJ5388A may be considered if footprint adaptation is possible.

FAQ

What does the 'A' suffix indicate for this part?

The 'A' suffix designates a standard voltage tolerance of plus or minus 10%.

Is this component RoHS compliant?

Yes, the 'e3' suffix indicates that the device is RoHS compliant and features annealed matte-tin plating.
